Australian Curriculum Year 5 Choose appropriate units of measurement for length, area, volume, capacity and mass (ACMMG108) Key Ideachoose appropriately from a range of strategies including es7ma7on, and knowledge of standards measures to approach various measuring tasks with confidence and accuracy. Resources FISH Scootle Variety of containers Measuring cups and jugs MABS Maths glossary Vocabulary Volume, capacity, measure, litres, millilitres, full empty, cubic metres, cubic cen3metres, size, shape dimensions, es3mate, compare, standard, metric system, unit Ac:vity Process: Volume or Capacity? The purpose of this ac3vity is to clarify the difference between capacity and volume. (Red Fish) Write the words “Volume” and “Capacity” on the board. Give students a notecard each and have them write down as many words as they card think of rela7ng to those two words. Alternately use inspira7on app on an iPad. Use a two column guide. List learners responses on the board aMer 23 minutes have elapsed. Use tally marks to gauge the popularity of certain responses. Ask learners to create their own defini7on for capacity. Have them record their defini7ons in their notebooks. Once everyone is done, ask students what the difference between capacity and volume. Discuss the students’ responses. To demonstrate the difference between the terms capacity and volume: Show the students a measuring jug (250mls). Explain to the students that we use the term capacity when talking about how much space there is available to hold something. Fill the jug with 175mls of milk. For example, the capacity of a cup, jug, bucket or box. Explain that volume is slightly different. Volume is a measure of the space taken up by something. Say, “This jug has a capacity of 250 ml”. Say, “The volume of milk in the jug is 175 ml”. Say, “The volume of milk needed to fill the jug is 250 ml”. Ask the learners, “Can you see the difference?”. The volume is how much milk is in the jug. Write the defini7ons of the terms capacity and volume into their maths glossary.

List  learners  responses  on  the  board  aMer  2-­‐3  minutes  have  elapsed.  Use  tally  marks  to  gauge  the  popularity  of  certain  responses.    

Ask  learners  to  create  their  own  defini7on  for  capacity.  Have  them  record  their  defini7ons  in  their  notebooks.  Once  everyone  is  done,  ask  students  what  the  difference  between  capacity  and  volume.  Discuss  the  students’  responses.    To  demonstrate  the  difference  between  the  terms  capacity  and  volume:  Show  the  students  a  measuring  jug  (250mls).        Explain  to  the  students  that  we  use  the  term  capacity  when  talking  about    how  much  space  there  is  available  to  hold  something.    u Fill  the  jug  with  175mls  of  milk.  For  example,  the  

capacity  of  a  cup,  jug,  bucket  or  box.        

Explain  that  volume  is  slightly  different.    Volume  is  a  measure  of  the  space  taken  up  by  something.      u Say,  “This  jug  has  a  capacity  of  250  ml”.  u Say,  “The  volume  of  milk  in  the  jug  is  175  ml”.  u Say,  “The  volume  of  milk  needed  to  fill  the  jug  is  250  

ml”.  Ask  the  learners,  “Can  you  see  the  difference?”.    The  volume  is  how  much  milk  is  in  the  jug.                  

   

Write  the  defini7ons  of  the  terms  capacity  and  volume  into  their  maths  glossary.  Adapted  from  a  Skillswise  fact  sheet:    h`p://www.bbc.co.uk/skillswise/factsheet/ma23capa-­‐l1-­‐f-­‐capacity                  Ac:vity  Process:  Litres  and  Milliliters  To  further  develop  personal  benchmarks  for    milliliters  and  litres.  Show  learners  2  containers,  one  holding  1ml  of  water  (medicine  spoon  would  be  appropriate)                  and  another  holding  1L  (a  1L  measuring  jug  would  be  appropriate).

u  How  many  mililitres  is  2.5  litres?  u  How  many  litres  in  1500  millilitres?  

                                               Less  than  1  Litre                                              About  1  Litre                                              More  than  1  Litre        

     Present  learners  with  a  variety  of  different  containers  with  the  standard  measures  removed  or  covered.  Some  sugges7ons  would  be:  Small  juice  bo`le,  Dish  soap  bo`le,  Large  milk  bo`le  (3L  if  possible),  Bo`le  of  Coke  (2L)  Oil  bo`le,  Tub  of  icecream    Ask  learners  to  iden7fy  which  ones  would  hold  less  than  a  litre,  about  a  litre  and  more  than  a  litre.    Ask  learners  to  sort  and  place  containers  under  the  headings,  less,  about  and  more.    Discuss  that  they  are  using  their  es7ma7on  skills  and  the  language  of  the  labels  reflects  this.  Challenge  learners  to  prove  their  es7ma7ons  are  correct  using  a  standard  measure.  Challenge  learners  by  asking  then  to  prove  their  es7ma7ons  through  demonstra7ons.    Explain  that  if  a  container  holds  less  than  1L,  it  is  likely  to  be  measured  in  millilitres  not  litres.  Set  up  a  classroom  display  and  encourage  students  to  bring  in  other  containers  to  add  or  create  a  chart  with  images  of  items.  The  7tle  for  the  display  should  be  units  of  capacity                    Ac:vity  Process:  Using  Standard  Units  of  Capacity    The  purpose  of  this  ac3vity  to  teach  students  to  formally  record  standard  measurements  using  litres  and  millilitres.  When  recording  measurements  in  litres  or  millilitres  it  is  important  to  select  the  correct  unit  depending  on  the  purpose.  If  dosing  a  baby  with  medica7on,  you  wouldn’t  measure  in  litres  or  when  filling  a  bathtub  you  wouldn’t  measure  in  millilitres.    Reiterate  that  1L  is  equivalent  to  1000  ml,  which  is  the  same  as  1  ml  being  1  thousandth  of  a  litre.  To  convert  litres  to  millilitres  you  must  mul7ply  by  1000  or  to  convert  millilitres  to  litres,  you  must  divide  by  1000.  To  teach  students  to  convert,  it  can  be  easiest  to  have  them  take  the  amount  in  litres  and  millilitres,  for  example  1560  ml  becomes  1  L  560  ml.    This  can  help  them  to  see  where  the  decimal  point  needs  to  be.    It  also  works  the  other  way,  1.89  L  becomes  1  L  890  ml.  Model  this  with  students:    1.  ‘A  baby’s  bo`le  has  a  scale  with  a  mark  every  10  ml  up  to  250  ml.  How  many  marks  are  on  the  bo`le?’  2.  ‘How  much  milk  will  be  in  the  5  bo`les  if  it  is  level  with  a)  is  at  the  20th  mark,  b)  is  at  the  17th  mark  and  c),  d)  and  e)  

are  level  with  the  25th  mark?  3.  Convert  the  total  amount  of  milk  in  the  bo`les  to  a  decimal

and  non-­‐standard.    For  example  jugs,  mugs,  teapot,  empty  coke/soM  drink  bo`les  of  various  sizes,  milk  bo`les,  jugs  with  no  scales,  buckets,  etc.

u Pose  the  ques7on:    I  need  to  find  out  about  the  capacity  of  these  containers  how  can  I  find  out?  u What  skills  do  I  need?  Discuss.  u Begin  to  es7mate  the  capacity  by  ordering  the  objects,  from  the  container  that  holds  the  smallest  amount  

to  the  largest  amount.  u Find  out  the  capacity-­‐read  scales.  Colour  the  water  to  make  reading  the  scales  easier.      u Write  labels  for  each  container.  u Assessment-­‐Observa7onal  Checklist

         u Give  learners  cen7cubes  and  ask  them  to  build  

this  prism.  Demonstrate  how  to  record  this  in  cubic  cen7metres.  V  =  L  x  W  x  H.  

u Further  demonstrate  how  to  calculate  the  volume  using  this  formula.    Use  further  examples  to  cement  the  process  and  then  have  student  work  on  calcula7ng  the  volume  of  rectangular  prisms    

u Learners  create  their  own  examples  independently  and  annotate  images  to  demonstrate  their  understanding  of  the  concept.  Store  in  mathema7cs    poroolio.

Learners  can:   D   ND  

1.  Read  a  scale  and  determine  capacity  

2.  Order  containers  from  the  smallest  to  the  largest  capacity  

This  interac7ve  resource  is  a  game  in  which  the  student  answers  ques7ons  about  the  capacity  of  familiar  containers  and  the  volume  of  water  used  for  everyday  tasks.  The  student  chooses  a  ques7on  and  then  selects  a  matching  7le  that  answers  the  ques7on.  Immediate  feedback  is  given,  and,  when  the  answer  is  correct,  the  7le  turns  over  to  reveal  part  of  a  picture.      Ac:vity  Process:  Linking  Cen:metres  and  Millilitres    The  purpose  of  this  aci3vity  is  to  teach  students  to  calculate  volume  using  a  formula  and  cubic  units.    u  Explain  that  it  is  possible  to  calculate  the  volume  of  3D  objects  

(boxes  and  containers)  in  cubic  units,  rather  that  relying  on  filling  containers  with  liquid.      

u  Ask  students,  “Why  is  this  important?”    For  example,  companies  will  need  to  know  how  much  of  their  product  will  fit  inside  a  box,  luggage  companies  need  to  know  how  much  travellers  can  fit  in  a  suitcase,  etc.
