Ask  students  to  compare  the  value  of  the    first,  second,  third  and  fourth  digits:    •  the  difference  between  the  two  numbers  •  the  difference  in  place  value                                        Ac.vity  Process-­‐Whole  Numbers  •  Place  PV  cards  on  the  floor  at  the  front  of  the  class  •  Four  students  randomly  select  four  single  digits  cards  (0-­‐9)    1.  Select  (or  ask  for  volunteer)  one  member  of  the  class  to  hold  up  card  at  front  of  the  room.      2.  Ask  learners  to  iden7fy  the  number  by  name  and  explain  what  the  number  represent  e.g.  quan7ty  of  ones,  9  ones,  odd,  

number,  one  less  than  ten,  3  lots  of  3  (highlight  vocabulary  ‘lots  of’)  3.  Select/ask  another  student  to  display  their  number.  Ask  class  to  discuss  where  the  student  should  stand  to  build-­‐on  the  

first  number.      4.  If  the  class  suggests  standing  on  the  leY,  ask  them  to  describe  what  the  digits  now  represents  (how  many  ones  they  have  

shown  e.g.  7  =  70  ones  or  7  lots  of  ten  (If  they  say  right,  redirect  them  so  that  they  are  building-­‐on).    •  Repeat  step  4  using  another  number,  focusing  on  the  use  of  mathema7cal  language  and  the  100  place  •  Repeat  step  4  using  another  number,  focusing  on  the  use  of  mathema7cal  language  and  the  1  000  place

Context  for  Learning  

Real  Life  Experience  :  How  many  books  do  you  think  we  have  in  our  school  library?  More  than  100?  More  than  1000?  How  could  you  find  out?  Where  could  you  find  things  that  come  in  groups  of  more  than  1000?  Brainstorm  a  list.  eg.  crowd  at  a  football  game,  cars  in  a  parking  lot.  How  can  we  check  its  accuracy?  

 2.    Wri?ng  Numbers  (small  group)    hfp://www.beam.co.uk/uploads/mompdf/Wri7ng-­‐numbers-­‐2.pdf    Students  roll  a  dice  and  arrange  them  to  make  a  three-­‐digit  number.  Write  the  number  in  the  appropriate  ring  on  the  sheet  Keep  playing  un7l  one  palyer  has  wrifen  three  numbers  in  each  of  three  different  rings  egg.  3  numbers  in  200  to  300,  another  three  in  300  to  400  and  another  in  over  600.  That  player  wins.                          3.    Important  Zero’s  (think,  share,  pair)  Resources:  0-­‐9  cards  with  extra  zero  cards  Learners  determine  the  placement  of  the  number  3  and  demonstrate  using  cards  and  saying  the  number.  000003  =  3  000030  =  thirty  000300  =  three  hundred  003000  =  3  thousand  030000  =  thirty  thousand  Learner  2  changes  two  zero  cards  in  a  selected  row  e.g.  000003  to  004103  =  Learner  1  responds  by  removing  the  zeros  that  are  not  needed  and  says  four    thousand,  on  hundred  and  three  or  4  lots  of  a  thousand,  one  lot  of  a  hundred  and  3  ones    Roles  are  reversed  and  play  con7nues  un7l  all  numbers  are  completed

•  Discuss  the  importance  of  the  no7on  of  between  two  points  ‘the  range’  

•  Explain  number  lines  don’t  always  start  at  0  ask                learners  to  suggest  a  range  that  would  be  suitable  if              they  had  to  locate  two  4  digit  numbers  1390-­‐1610  

•  Using  a  number  line  compare  1  390  with  1  610    

•  Discuss  place  value  and  digits  ending  in  zero.  Ask  how  many  ones,  tens,  hundreds  

•  Ask  students  to  select  10  as  a  way  of  dividing  the  range  by  10.  Ask  why  this  would  take  a  long  7me?  

•  Ask  students  to  think  about  a  number  larger  than  ten  but  smaller  than  a  thousand  

•  Using  100  locate  a  number  selected  at  random  e.g.1  560  on  the  number  line

Vocabulary  Building    •  I  have  compared  two  or  more  numbers  and  place  values  in  many  maths  ac7vi7es.  I  compare  one  thing  to  another  

based  on  a  criteria.          Background  Knowledge  of  Place  Value  is  essen7al  for  understanding  numbers  in  the  thousands.  Learners  should  already  know  that  10  ones  equal  1  ten,  10  tens  equal  1  hundred.  They  con7nue  to    learn  that  10  hundreds  equal  1  thousand.      There  is  a  variety  of  ways  to  write  4  digit  numbers.  eg.  standard  form,  expanded  form  and  word  form.    Learners  need  to  be  able  to  convert  numbers  in  the  hundreds  from  standard  form  to  expanded  form  and  back  again.      Teaching  metacogni7on,  (thinking  about  thinking)  is  important.  Learner  reflec7on  and  self  assessment  is  an  important  part  of  the  learning  process.  It  is  a  way  in  which  learner  internalise,  clarify  and  make  sense  of  their  experience.  It  can  also  be  a  powerful  assessment  tool,  providing  the  opportunity  for  teachers  to  assess  students’  mathema7cal  processes.    Competent  problem-­‐solvers  are  efficient  at  keeping  track  of  what  they  know  and  how  well  their  afempts  to  solve  the  problem  is  proceeding.  They  con7nually  ask:  •  What  am  I  doing?  •  Why  am  I  doing  it?  •  How  will  it  help  me?  

Striving  to  provide  learning  opportuni7es  that  encourage  success  with  problem-­‐solving  leads  to  the  raising  of  the  intellectual  quality  of  the  mathema7cs    classroom.  The  FISH  acronym  and  process  provides  a  schema  for  developing  a  focus  on  problem-­‐solving  skills.  Teachers  need  to  explicitly  teach  how  to  analy7cally  read/understand  problems.  Shared  Thinking  Word  Wall:  Learners  and  teachers  need  to  develop  a  shared  vocabulary  to  enable  clear  expression  of  their  thinking  processes.  Think  'me,  think  aloud,  suggest  ideas,  brainstorm,  imagine,  how  well  did  it  work?    Links  to  other  MAG’s    Year  2  MAG  2.1.3  Place  Value  1,  MAG  2.3.3  Place  Value  3  Year  3  MAG  3.1.3  Place  Value  1,  MAG  3.3.3  Place  Value  3  

Inves.ga.on:  Take  an  ar7cle  from  the  font  page  of  a  newspaper.  How  far  down  the  ar7cle  would  you  need  to  go  to  reach  1000  words?  (approximate)      •  Does  it  change  depending  on  the  size  of  the  font?    •  CHECK:    •  Can  students  work  with  numbers  that  are  more  and  

less  than  1000?    •  Do  they  understand  the  concept  of  1000?    •  Use  a  Frayer  model  to  show  your  understanding    Assessment  Create  observa?onal  checklist  to  assess  students  knowledge  of  place  value  to  3  digits  and  4  digits.    Check  to  see  if  students  are  able  to  use  appropriate  mathema7cal  language  (link  back  to  word  wall)  Can  students  use  correctly,    standard,  expanded  and  wrifen  forms  of  numbers.    •  Photographic  evidence  from  games/ac7vi7es    •  Frayer  Model  diagrams  

The  Frayer  instruc7onal  strategy  promotes  cri7cal  thinking  and  helps  students  to  iden7fy  and  understand  concepts.  The  model  can  be  used  with  the  en7re  class,  small  groups,  or  for  individual  work.  It  draws  on  a  student's  prior  knowledge  to  build  connec7ons  among  new  concepts  and  creates  a  visual  reference  by  which  students  learn  to  compare  afributes  and  examples.
