Grade 1 Parent Information Unit 6: Using Numbers in Many Ways

What Your Child Will Learn: Unit 6 continues to build on number fluency and the composition and decomposition of numbers and shapes. This unit will continue to build on the students’ understanding of adding and subtracting tens, using shapes to compose new shapes, as well as split shapes into equal parts.

MORE SPECIFICALLY, CHILDREN WILL LEARN HOW TO: • Add a two-digit number and a multiple of 10 • Use place value and properties of operations strategies to subtract multiples of 10 • Use the relationship between addition and subtraction to subtract multiples of 10 • Build and draw shapes to possess defining attributes • Split circles and rectangles into two and four equal shares • Describe the shares using the words halves, fourths, and quarters • Describe the shares using the phrases half of, fourth of, and quarter of • Describe the whole as two of, or four of the shares • Understand that decomposing a shape into more equal shares creates

smaller shares • Use concrete models and drawings to subtract multiples of 10 • Add a two-digit number and a one-digit number • Add using concrete models and place value strategies • Relate addition to subtraction as a strategy • Understand that adding two-digit numbers involves adding tens to tens and ones

to ones • Understand that adding sometimes involves composing a ten • Review and combining of various standards taught throughout first grade

Standards – Part A: 1.NBT.4, 1.NBT.6; Part B: 1.G.1, 1.G.2, 1.G.2; Part C: 1.NBT.4, 1.NBT.6

Some samples of the type of problems your child will be seeing in this unit. Using number bonds, composing and decomposing Strategies to add two and one digit numbers.

Joan has 80 cents to spend at the store. She buys a soda for 50 cents and a banana for 20 cents. How much does Joan have left? Method 1: 80- 50= 30 cents, then 30- 20=10 cents. Method 2: 50+20=70 cents, and 80-70= 10 cents remaining There are multiple ways in which a student could complete this answer. They could also use dimes, blocks, a number chart or a number line to help them solve and demonstrate their understanding of the problem.

Activities at Home

• Quiz your child on addition and subtraction facts with numbers up to 10. • Practice mental math, giving them problems with sums to 40, and have them explain how they figured it out. • Practice 10 more/10 less questions. For example: “What is 10 less than 40?” “What is 10 more than 52?” • Encourage your child to use more than one method of solving an addition or subtraction problem. They will be learning more, see if they know any new ones! • Measure objects around the house using Legos or paper clips. Tell how many long an object is. • Practice reading digital and analog clocks to the hour and the half-hour.

Questions to Support your Child with Math Homework: • What do the directions say? • What do you need to know? • What math vocabulary do you not understand? • Can you make a model (drawing) or explain your thinking?

Besides supporting your child with homework, show the importance of learning math by helping your child connect math with daily live. Point out your own activities that involve mathematics, such as deciding if you have enough money to buy items on a shopping list, finding the total number of fruits or vegetables you need to cook dinner for the week, or look at the time to make sure you will be on time, or find out when their favorite show might start.

1.er Grado Información para los padres

Unidad 6: Utilizar los números de varias maneras

Lo que su hijo aprenderá: La unidad 6 sigue basándose en la fluidez con los números y la composición y descomposición

de números y figuras. Esta unidad continuará desarrollando en los estudiantes la comprensión

de la suma y resta de decenas, utilizando figuras para formar nuevas figuras, así como dividir

las figuras en partes iguales.

MÁS ESPECÍFICAMENTE, LOS NIÑOS APRENDERÁN CÓMO: • Añadir un número de dos dígitos y múltiplos de 10

• Utilizar el valor posicional y las propiedades y estrategias de las operaciones para restar

múltiplos de 10

• Usar la relación entre la suma y la resta para restar múltiplos de 10

• Construir y dibujar figuras para que tengan atributos que las definan

• Dividir círculos y rectángulos en dos y cuatro partes iguales

• Describir las partes usando las palabras mitades, cuartos y cuartas partes

• Describir las partes utilizando las frases: la mitad de, la cuarta parte de, y un cuarto de

• Describir un entero como dos o cuatro de las partes

• Entender que la descomposición de las figuras en más partes iguales crea partes más

pequeñas

• Utilizar modelos y dibujos concretos para restar múltiplos de 10

• Sumar un número de dos dígitos y un número de un dígito

• Sumar utilizando modelos concretos y estrategias de valor posicional

• Relacionar la suma y la resta como una estrategia

• Entender que la suma de números de dos dígitos implica la suma de decenas con

decenas y unidades con unidades

• Comprender que la adición algunas veces implica componer una decena

• Revisión y combinación de diversos estándares que se han enseñado a lo largo del primer

grado

Estándares – Parte A: 1.NBT.4, 1.NBT.6; Parte B: 1.G.1, 1.G.2, 1.G.2; Parte C: 1.NBT.4, 1.NBT.6

Algunos ejemplos del tipo de problemas que su hijo van a ver en esta unidad. Usando vínculos numéricos,

componer y descomponer

Estrategias para sumar números

de uno y dos dígitos

Descomponer números grandes para

sumar y restar

Descomponer 56 me permite

hacer 50-20=30 y después

sumar 30+6=36

Joan tiene 80 centavos para gastar en la tienda. Ella compra un refresco por 50 centavos y un plátano

por 20 centavos de dólar. ¿Cuánto le queda a Joan?

Método 1: 80 - 50 = 30 centavos, después 30 - 20 = 10 centavos.

Método 2: 50 + 20 = 70 centavos, y 80 - 70 = 10 centavos restantes

Hay varias formas en las que un estudiante puede llegar a esta respuesta. También podría utilizar

monedas de diez centavos, bloques, una tabla numérica o una línea numérica para ayudarles a

resolver y demostrar su comprensión del problema.

10.

• Practique el cálculo mental, dándoles problemas con sumas hasta 40, y pida que

le explique cómo lo resolvió.

• Practique preguntas de 10 más o menos 10. Por ejemplo: "¿Cuánto es 10 menor

que 40?" "¿Cuánto es 52 más que 10 "?

• Anime a su hijo a usar más de un método para resolver un problema de suma o

resta. Ellos van a aprender más. ¡Vea si conocen algunos nuevos!

• Medir objetos alrededor de la casa usando Legos o clips de papel. Decir qué tan

largo es un objeto.

• Practique la lectura relojes digitales y analógicos a la hora y la media hora.

Preguntas para apoyar a su hijo con la tarea de matemáticas:

• ¿Qué dicen las instrucciones?

• ¿Qué necesitas saber?

• ¿Qué vocabulario matemático es el que no entiendes?

• ¿Puedes hacer un modelo (dibujo) o explicar tu forma de pensar?

Además de apoyar a su hijo con la tarea, demuéstrele la importancia de aprender

matemáticas ayudando a su hijo a relacionar las matemáticas con la vida diaria.

Señale sus propias actividades que implican las matemáticas, tales como decidir si

tiene suficiente dinero para comprar artículos en una lista de compras, encontrar el

número total de frutas o verduras que necesita para cocinar la cena para la semana,

o ver la hora para asegurarse de va a llegar a tiempo, o averiguar cuando podría

empezar su programa favorito.

가정에서의 활동

• 최대 10 까지의 숫자 더하기 및 빼기를 자녀에게 퀴즈내기 . • 암산 연습, 40 이 합인 문제를 그들에게 주고 , 그들이 그것을 알아낸 방법을 설명하도록 한다. • 10 많이/10 적게 문제를 연습한다. 예: “ 40 보다 10 작은 것은?” “52 보다 10 많은 것은?” •덧셈 또는 뺄셈 문제를 풀기 위해 한가지 방법 이상을 사용하도록 귀 자녀를 격려한다. 그들이 새로운 방법을 아는것은 더 많은것을 배우는 것이다! •레고 또는 종이 클립을 사용하여 집 주변에 있는 물체를 측정한다. 물체가 얼마나 긴지 말한다. •디지털 및 아날로그 시계로 시간 및 30 분 단위로 읽기를 연습한다.

수학 숙제에서 자녀를 돕기 위한 질문들: • 지시사항이 말하는 것은 무엇인가? • 알아야 할 필요가 있는것은 무엇인가? • 수학의 어떤 어휘를 이해하지 못하는가? • 모델(그림)을 만들거나 너의 생각을 설명할 수 있는가?

숙제에서 자녀를 도와주는 것 이외에, 수학과 일상 생활을 연결시켜주는 도움을 줌으로써 자녀에게 수학의 중요성을 보여준다. 쇼핑 목록에 있는 물품들을 사기 위해 충분한 돈을 갖고있나, 이번 주 저녁 요리를 위해 필요한 야채나 과일의 총 수는 몇개인가 또는 제 시간안에 도착하기 위해서 또는 좋아하는 쇼가 시작하는 시간을 확실히 하기 위해 시간을 보는 것과 같이 수학이 포함된 활동들을 알아본다.

8+2=10, therefore I can decompose 7 into 5 and 2, add the 2 to 8 to make 10, then add 5 to make 15. OR, I could also decompose 8 into 3 and 5 and continue with the same process with the other number.

Decomposing 16 allows me to do 10-8=2, then adding 2+6=8.

Decomposing 56 allows me to do 50-10=40, then adding 40+6=46. Most of this process

16 - 8 = 5 6 - 2 0 =

30+20=50 and 6+0= 6, so 50+6=56 Decomposing larger numbers to add and subtract
