ALL SAINTS BOOK CLUBS 2019!

All Saints School, through the generous support of its C.S.P.C., is once again participating in the Ontario Library Association Forest of Reading Program. Junior and Intermediate students are able to join our Silver Birch reading club. Members set personal reading goals and read independently during book club and personal time. Students share their opinions and feelings about nominated literature during weekly “book talk” morning meetings with their peers. The Book Club runs from February to mid-April, once a week during AM recess. Further information about the book club will follow – so listen to morning announcements for details! Primary students will be part of the O.L.A. Blue Spruce program within their individual classrooms. All clubs aim to promote increased interest in reading and responding to books. Congratulations to the All Saints community for their enthusiasm and commitment toward fostering literacy!

March Break and Extended Vacations

This year, the break will be from March 11th to March 15th. If, however, you plan on extending your vacation, or taking a vacation at another time during the year, please notify your child’s teacher, as well as the office, as appropriate paperwork needs to be completed for an extended absence over and above regular school holiday time.

Lost and Found Articles We would ask that you encourage your child to check the lost and found articles at school if they are missing articles of clothing. The pile of lost clothing in the lost and found has been increasing. If these articles are not claimed by

March 11th, they will be donated to charity. You may also call the school and make an appointment to come and check the lost and found articles.

It will take place on Friday March 1st with the Grade 4-8 assembly beginning at 9:15 a.m. and including the Honour Roll and Grades 1-3 at 12:45 p.m. We will also continue to recognize one student per grade for the Virtue of the Month and the Ontario Catholic Graduate Expectations.

Safe Arrival and Departure

Safe & Caring Schools

Visitors to the School

Toronto Catholic District School Board policy states that all visitors to the school MUST report to the office. This is foremost to ensure

the safety of all students. In an effort to promote the independence of the students and to ensure the integrity of programs by minimizing interruptions during class time, we request that students arrive on time for the school day with all the items they require (i.e. homework, lunch, physical education clothes etc.)

Allergen Aware

Please take special note that we have children in our school who have very serious allergies to nut products. According to Sabrina’s Law, we must make every effort to maintain a nut free environment in order to help keep all children safe. We ask that you not bring in or send in any food items to be shared with other students in the class. Please note that baked goods and treats are not permitted. We apologize for the inconvenience; however, we are certain you will agree that these measures are necessary in order to ensure the safety and welfare of our children.

Personal Property

The school does not take any responsibility for the loss or theft of personal items brought onto school premises by students. The school will therefore, not reimburse or replace lost or stolen articles, under any circumstances. This will include all articles of clothing (label items with a marker); personal school supplies such as fancy or expensive pens, markers, binders and pencil cases, etc.; simple or electronic toys, calculators, laptops, iPod’s, CD’s, cell phones, etc. Please note that collector cards of any kind are not permitted, in addition to all cell phones and any other social media devices. These items will be immediately confiscated by staff and brought to the Principal’s attention. We ask both parents and students for their full co-operation in this matter. (Please note that the Board’s insurance policy does not cover property owned by staff or students).

We continue to remind you to contact the school before 8:30 a.m. if your child is going to be absent from school. If we are unable to take your call, you can leave a message on our answering machine. Please ensure that we have a current emergency number where you can be contacted. If you are picking up your child early, please send a note to your child’s teacher. Please be sure to report to the office to sign them out. If you are returning before the end of the day, please sign your child back in at the office. All students on buses must ride the buses to and from school every day.

Reporting of cancellations or closures due to inclement weather

Cancellation of school bus transportation or school closures due to inclement weather will be reported through the following vehicles: News releases to all media outlets in Toronto (Note: although the news release is provided to the media outlets, there is no guarantee that all

television and radio stations will broadcast the information in a timely fashion.) Communications will endeavour to send an email to everyone on exchange to

advise them of any cancellations or closures. Communications will also endeavour to send out the information electronically to E-News subscribers (Note: If you do not already subscribe to E-News, but wish to do so, please visit our website at www.tcdsb.org and click on the E-News icon on the top right hand side of the homepage). Updates will also be posted on the Board’s 24-hour information line, 416-222-8282, extension 2873, as well as it being posted on the Board’s website at www.tcdsb.org or www.tcdsb.org/weather.html , as well as on Twitter @TCDSB and @AllSaintsTCDSB. The Transportation Department will also post this information on its website at http://www.schoolbus.to/c_home.asp Please note that if buses are cancelled in the morning, they will not run in the afternoon.

Inclement Weather On days when the weather is inclement, the students may be permitted to enter the building at 8:15 am. On such days, the recess periods may be indoor and those students who stay for lunch will be supervised in the building. Weather conditions must be particularly severe, cold weather alone does not warrant an early entry into the building or indoor recess periods. Those decisions will be made accordingly. We believe that children profit greatly from recess breaks as they get out into the fresh air and burn off some energy in play activities. This will make them more alert and ready to continue their studies when they come in. It is important for children, particularly the younger children in the primary grades, to come to school dressed properly for the weather. A reminder to everyone that students who are well enough to be at school are well enough to go out for recess. We do not have personnel to supervise students who wish to stay in for recess due to illness. If they are too ill to go out for recess, then they should be home for the day. This will allow for quicker recovery and less teaching and learning time lost to illness. For information on the TCDSB Guidelines for weather conditions, please go to

http://www.tcdsb.org/FORSTUDENTS/HealthandSafety/Documents/GuidelinesforWeatherConditions.pdf

Safe Arrival

To report your child as late of absent, please use one of the following options: Call: 1(833) 251-3286 Online: go.schoolmessenger.ca Mobile App: SchoolMessenger Attendance referrals will be sent to the Social Worker and persistent tardiness may result in progressive discipline. Students are expected to arrive prior to the bell. All students are to arrive prepared to work and learn. Preparation includes completing daily assignments that are done to the best of the individual student’s ability and the responsibility to study in advance for tests.

Parking

A reminder that the school parking lot is for staff only. Please do not use it for parking as we do not have enough spots for staff. Our students have been instructed not to enter the

parking lot for safety reasons. Father Glaba has graciously volunteered the use of the church parking lot for our parents. Please observe and respect the “in” and “out” flow in the church parking lot. There is absolutely NO PARKING in the handicapped spaces, or in the fire route at the front of the school. The fine is substantial and we need to have those spaces clear for their appropriate use by those that need them. A reminder to all that Renault is strictly a “Drop Off Kiss and Ride”, and there is absolutely no parking permitted within the sign boundaries. Everyone is encouraged to use the Kiss and Ride in the school parking lot. Police and Parking Enforcement have assured us that Renault will be closely monitored for proper use.

Medication

Principals, teachers and support staff of the TCDSB are not permitted to administer any type of prescription medication during the school day, unless we have written authorization signed by you the parent, and the prescribing physician. The forms to dispense any medication must be updated on a regular basis and are available from the school principal. Please be advised that staff in TCDSB schools will not dispense non-prescription medications to students. Students who need “puffers” should have one at school and at home. All medications will be stored in the main office. Please notify the school if your child suffers from any type of allergy.

Lunch Time Supervisors If anyone is interested in assisting the school as a Lunchtime Supervisor, please contact the office for an application package.

Chess Club Ms. Buongiorno heads up the chess club and it continues to provide great training from professional coaches. We will participate in the Chess Tournaments sponsored by the Board. Dates: TBD

“I have decided to stick with love, for I know that love is ultimately the only

answer to mankind’s problems.” Martin Luther King Jr.

A Matter of Safety Now that the winter season has arrived, there are a few issues that need to be addressed. 1. Please ensure that your children

are dressed appropriately for the cold weather. They should have mittens or gloves, a hat, a winter coat, boots and possibly a scarf. Unless we have extreme wind chill factors, children will be out for recess. Label your child’s belongings to avoid any mix-ups with other children.

2. We request that you send a pair of shoes to be kept at school so that children can wear them after removing their boots. Children will not be allowed to wear their boots inside the classroom. If your child wears his/her running shoes to school, they will need to have a second pair of running shoes to be used for gym classes. No outside shoes are to be worn in classes.

3. Snow pants are also encouraged. It is impossible to keep young children off the snow. Snow pants will keep them dry outside.

4. Please reinforce what we are emphasizing at school; that is, that snow must remain on the ground. Once snow is picked up, it is easily made into a snowball and thrown at others. Snowball throwing can lead to serious injury and students will be progressively consequenced.

Extra-Curricular Activities

School Hockey Team

Our All Saints Titans Hockey team is gearing up for a fantastic season! With their coaches, the team has been practising on Wednesdays at Pine Point Arena. Tournaments are scheduled to begin late March and early April. Best of luck!

W5H The All Saints’ W5H team is gearing up for another year of trivia and competition. The format is similar to Jeopardy with contestants buzzing in with answers to questions involving general knowledge, math, language, pop culture and sports. The school has two teams, one at the junior grade level and one at the intermediate level. Competitions take place in February and April and give students a chance to show off their vast array of knowledge. We look forward to an exciting year!

Valentine Candygram Drive! This year, we continue to offer our students an opportunity to buy candygrams for 50 cents each and send them out to students and teachers in our school. We will be selling candygrams from January 28th until February 8th, and deliver them to the classes on Wednesday, February 13th, 2019. Every morning at 11:00 am, students will go to the classrooms to sell and students will have the opportunity to buy the candygrams, at this time. Students always look forward to the candygrams, and we hope that this year, our Candygram Drive will be a success. Happy messages for a Happy Valentine’s Day. Candygram Committee

Junior Boy’s Indoor Soccer

On January 30th the junior boy’s indoor soccer team will compete in their divisional tournament at St. Demetrius. We wish them the best of luck as they will be defending their second place title. The team members are: Ethan Muia, Aiden Galluzo, Tomas Delgado, Andres Valderama, Domenico Pugliese, Jason Belluzzo, Taijuan Castello, Matteo Mandarino, Nicholas Rose, Stephen Pace, Jayden Danga, Francesco Di Fonzo, Francesco, Gallippi, Francesco Mastrogiovanni, Ethan Molla, and Sebastian Nana Raso. Mr. Langiano, Mr. Lombardo, and Mr. Grossi would like to wish the team the best of luck.

Junior Girls’ Indoor Soccer

All Saints Titans Basketball

The intermediate basketball season is once again upon us and both teams are gearing up to put out solid efforts for the 2019 campaign. Coach Takacs has welcomed new additions into this year's season with Coach Pereira and Ostojic providing their expertise with practices and games. The boys' will be kicking off their year officially on February 5th, at St. Jude. If successful, the boys could find themselves with back-to-back divisional pennants, which would be a first for Mr. Takacs in his coaching career in terms of boys' basketball. The boys are hoping their experience from last season translates into victory this year. Last year saw the boys eliminated in the Regional round quarter-finals, but it wasn't without exciting highlights. The knock-out came after they scraped together a thrilling 33 - 26 win in overtime against St. Eugene at the hands of eventual city finalists, St. Bernard. The boys kept the game close until the last three minutes of regulation, but fell 33 - 17 to Bernard when the buzzer sounded. February 7th will see the girls' squad travel to St. Jude to try and regain their dominance of divisionals that had a run of championships from 2013 - 2017. Last year's heart-wrenching 18-17 loss still stings a little as the girls were, on three separate occasions, just a bounce away from hitting a winning bucket. All of these attempts happened with less than 30 seconds. Although the ladies might lack the height we've been blessed with the past few seasons, they are not short on heart. 2019 does offer a unique opportunity for the girls however. If they place 2nd in their division they will be able to participate in a second chance tournament being hosted at St. Clement on Feb. 12th. The extra day will have all of the 2nd place teams from the seven divisions competing against each other in order to get the eighth and last spot in the regional round. Best of luck to both teams!

On Thursday, January 31st, 2019, the junior girls’ indoor soccer team will be attending the soccer tournament at St. Demetrius School. We are busy practicing and preparing for the tournament, as we are looking to regain our championship title! The members of this year’s girls’ junior indoor soccer team are: Alexis Giaquinto, Belle Esposto, Natasha Horvath, Cassandra Cescon, Ainsley Somerville, Selina Grgic, Isabella Centritto, Isabella Mariano, Julia Pizzonia, Sophia Pisan, Adriana Gallucci, Naiyah Elder, Georgia Pagliaroli, Elena Sipar, and Josephine Nucara. Mme Ferrarelli, Ms. Makhlouf and Mme Sessa would like to wish the girls good luck! Go Titans Go!

Lunch Time Supervisors If anyone is interested in assisting the school as a Lunchtime Supervisor, please contact the office for an application package.

MENTAL MATH STRATEGIES

ADDITION Break Up the Numbers Strategy This strategy is used when regrouping is required. One of the addends

is broken up into its expanded form and added in parts to the other

addend. For example 57 + 38 might be calculated in this way: 57 + 30 is

87 and 8 more is 95.

Front-End (left to right) Strategy This commonly used strategy involves adding the front-end digits and

proceeding to the right, keeping a running total in your head. For example,

124 + 235 might be calculated in the following way: Three hundred (200 +

100), fifty (20+30) nine (4 + 5).

Rounding for Estimation Rounding involves substituting one or more numbers with “friendlier”

numbers with which to work. For example, 784 + 326 might be rounded as

800 + 300 or 1100.

Front-End Estimation This strategy involves adding from the left and then grouping the numbers

in order to adjust the estimate. For example 5239 + 2667 might be

calculated in the following way: Seven thousand (5000 + 2000), eight

hundred (600

+200) – no, make that 900 (39 and 67 is about another hundred). That’s

about 7900

Compatible Number Strategy Compatible numbers are number pairs that go together to make “friendly”

numbers. That is, numbers that are easy to work with. To add 78 + 25

for example you might add 75 + 25 to make 100 and then add 3 to make

103.

Near Compatible Estimation Knowledge of the compatible numbers that are used for mental

calculations is used for estimation. For example, in estimating 76 + 45 +

19 +26 +52, one might do the following mental calculation: 76 + 26 and 52

+ 45 sum to about 100. Add the 19. The answer is about 219.

Balancing Strategy A variation of the compatible number strategy, this strategy involves taking

one or more from one addend and adding it to the other. For example, 68

+ 57 becomes 70 + 55 (add 2 to 68 and take 2 from 57)

Clustering in Estimation Clustering involves grouping addends and determining the average. For

example, when estimating 53 + 47 + 48 + 58 +52, notice that the addends

cluster around 50. The estimate would be 250 (5 x 50)

Special Tens Strategy In the early grades, students learn the number of pairs that total ten – 1

and 9, 2 and 8, 3 and 7, and so on. These can be extended to such

combinations as 10 and 90, 300 and 700, etc.

Compensation Strategy In this stage, you substitute a compatible number for one of the numbers

so that you can more easily compute mentally. For example, in doing the

calculation 47 + 29 one might think (47 + 30) – 1.

Consecutive Number Strategy When adding three consecutive numbers, the sum is three times the middle

number.

Doubles and Near Doubles Start with double fact they know, then pick closely related to an “almost

double” followed by some near doubles

25+25, 25+26, 25+24, 25+28 30+30, 29+31, 28+30, 29+29

Splitting Split numbers into place value of digits 28 + 44 = 20 + 40 + 8 + 4 376 + 243 = 300 + 200 + 70 + 40 + 6 + 3

Making Jumps of Ten Keep one number whole and jumps of ten are added to

it 28 + 44 = 44 + 10 + 10 + 8 (decompose 8 into 6 and

2)

3 486 + 1 214 = 3 486 + 1 000 + 200 + 10 + 4

Moving to the Next Friendly Number Units are added first to reach a friendly number 98 + 37 = 98 + 2 + 35 = 100 + 35 = 135 27 + 49 = 26 + 50 36 + 118 = 34 + 120 227+164=230+161

Swapping: Switching digits (all 9 digits in same number) 39 + 92 = 32 + 99 293+919=999+213 (then move to nearest

friendly number and compensate (1000+212=1212)

SUBTRACTION Compatible Number Estimation Knowledge of compatible numbers can be used to find an estimate when

subtracting. Look for the near compatible pairs. For example when

subtracting 1014 – 766, one might think of the 750 – 250 pairing.

Front-End Strategy When there is no need to carry, simply subtract from left to right. To

subtract 368 – 125 think 300 – 100 = 200, 60 – 20 = 40, 8 – 5 = 3.

The

answer is 234.

Front-End Estimation For questions with no carrying in the highest two place values, simply

subtract those place values for a quick estimation. For example, the

answer to $465.98 - $345.77 is about $120.00

Compatible Numbers Strategy This works well for powers of 10. Think what number will make the

power of 10. For example, to subtract 100 – 54, think what goes with 54

to make

100. The answer is 46.

Equal Additions Strategy for Subtraction This strategy avoids regrouping. You add the same number to both the

subtrahend and minuend to provide a “friendly” number for subtracting,

then subtract. For example, to subtract 84 – 58, add too to both numbers

to give 86 – 60. This can be done mentally. The answer is 26.

Compensation Strategy for Subtraction As with addition, subtract the “friendly” number and add the difference.

For example, $3.27 - $0.98 – ($3.27 - $1.00) + $0.02 = $2.29

“Counting On” Strategy for Subtraction Visualize the numbers on a number line. For example, 110 – 44. You

need 6 to make 50 from 44, then 50 to make 100, then another 10 to get

56.

“Counting On” Estimation “Counting On” can also be used for estimation. For example, to estimate

894 – 652, think that 652 + 200 gives about 850. Then another 50 gives

about 900. The difference is about 250

about 900. The difference is about 250 TCDSB Math Dep
