Number  and  Operations:  Fractions:  Extend  understanding  of  fraction  equivalence  and  ordering    4.NF.1  Explain  why  a  fraction  a/b  is  equivalent  to  a  fraction  (n  x  a)/(n  x  b)  by  using  visual  fraction  models,  with  attention  to  how  the  number  and  size  of  the  parts  differ  even  though  the  two  fractions  themselves  are  the  same  size.  Use  this  principle  to  recognize  and  generate  equivalent  fractions.  (Grade  4  expectations  in  this  domain  are  limited  to  fractions  with  denominators  2,  3,  4,  5,  6,  8,  10,  12,  100.)  

• I  can  recognize  and  create  equivalent  fractions    • I  can  explain  why  they  are  equal.

2. Assessment  Task  (ACEI  4-­‐Informal  and  formal  assessment.  Candidate  plans  appropriate  formative  and  summative  assessments  to  guide  and  assess  student  learning,  including  criteria)  

Students  will  solve  different  problems  involving  equivalent  fractions.  They  will  create  fractions  and  the  corresponding  equivalent  fraction  based  on  their  own  fraction  or  based  on  the  model.  They  will  need  to  identify  different  equivalent  fractions  based  on  a  given  model.  I  will  assess  students’  completed  work  using  WB,  DP,  MP  and  ME  from  the  rubric  on  page  7.  

3.  Activities/Instructional  Strategies  (ACEI  3.1:  Knowledge  of  students  and  community;  integration  of  knowledge  for  instruction;  ACEI  3.3:  Critical  thinking,  problem  solving  and  performance  skills;  ACEI  3.4:  Active  engagement  in  learning;  ACEI  3.5:  Communication  to  foster  learning)

a. Write  on  the  board:  5  dimes  are  equivalent  to  2  quarters                                    3  +  5  is  equivalent  to  5  +3  

       ½  is  equivalent  to  50%  b. Read  the  sentences  aloud.  c. Ask  students  to  think  for  a  minute  what  they  think  the  term  “equivalent”  means.  d. Select  a  few  students  to  share  what  they  think  the  term  “equivalent”  means.  e. Use  students’  paddler  number  if  necessary.    f. Explain  the  term  “equivalent”.  (Equivalent  means  the  same  value.)  g. Ask  students  what  are  fractions.  h. Select  students  to  share  their  answers.  (Fractions  are  numbers  that  can  represent  a  

part  of  a  whole)  i. Explain  today’s  lesson.  (Today,  we  will  be  learning  about  equivalent  fractions.)  j. Ask  students  to  think  for  a  minute  what  they  think  equivalent  fractions  are.  (Since  

you  know  what  the  term  equivalent  means,  what  do  you  think  equivalent  fraction  means?)  

k. Ask  students  to  quickly  share  their  answers  with  the  person  sitting  next  to  them  or  the  person  across  from  them.  

l. Obtain  the  class’  attention  by  initiating  the  attention  getter.  (Teacher  says  class  class  and  students  respond  with  yes  yes)  

m. Select  a  few  students  to  share  to  the  class.  n. Explain  equivalent  fractions.  (Equivalent  fractions  are  fractions  that  represent  the  

same  value.  Equivalent  fractions  name  the  same  amount.)  o. Share  “I  can”  statements:    

i. I  can  recognize  and  create  equivalent  fractions.    ii. I  can  explain  why  they  are  equal.  iii. I  can  work  with  others  when  completing  a  task.  

p. Provide  a  math  connection  to  real  life.  (Chef  in  a  restaurant  that  needs  to  double  his  recipe  in  order  to  make  enough  of  the  dish.  At  home,  your  parents  have  to  cook  enough  for  the  family  and  your  friends  came  over  they  have  to  increase  the  fraction

of  ingredients  used  to  cook  dinner  or  dessert.)    2. Focus/Mini  lesson  (I  do)  (5  min):    

a. Place  three  fraction  circles  on  the  board.  (Fourths,  Eights  and  Twelves)  b. Explain  that  the  fraction  circles  are  pretend  “pizzas.”  c. Select  3  students  to  stand  next  to  the  fraction  circles/pizzas.  d. Explain  that  each  student  will  have  one  whole  pizza.    e. Inform  the  student  that  he/she  ate  ¼  of  the  pizza.  (You  ate  1  piece  of  the  4  pieces)  f. Instruct  the  student  with  the  four  slices  to  grab  ¼  of  his  or  her  pizza  to  indicate  how  

many  he/she  ate.  (So,  ____  is  holding  ¼  of  the  pizza  which  means  she  ate  a  part  of  a  whole.)  

g. Inform  the  next  student  that  he/she  ate  2/8  of  the  pizza.  (You  ate  2  pieces  of  the  8  pieces)  

h. Instruct  the  student  to  grab  2/8  of  his  or  her  pizza  to  indicate  how  many  he/she  ate.  i. Inform  the  last  student  that  he/she  ate  3/12  of  the  pizza.  (You  ate  3  pieces  of  the  12  

pieces)  j. Instruct  the  student  to  grab  3/12  of  his  or  her  pizza  to  indicate  how  many  he/she  

ate.    k. Instruct  the  class  to  compare  the  pieces  that  the  3  students  “ate”  from  the  three  

pizzas.  i. Review  definition  of  compare.  ii. Use  finger  signs.  (Place  a  1  in  the  air  if  you  think  they  are  the  same,  a  peace  

sign  if  you  think  they  are  different.)  l. Select  a  few  students  to  share  what  they  observed.  (What  do  you  notice  about  the  

amount  of  pizza’s  ___,  ____,  and  ______  ate?  What  do  you  notice  about  the  fractional  parts  that  they  ate?  What  do  you  notice  about  the  left  over  pizzas  from  each  of  the  students?  Who  ate  more  of  their  pizza?  Who  ate  less?)  

m. Guide  students  to  understand  that  the  “eaten  pieces”  are  equivalent  fractions.    i. Place  the  eaten  pieces  on  top  of  the  other  eaten  pieces  to  visually  show  that  

they  are  all  equivalent.    n. Write  the  equivalent  fractions  on  the  board  with  the  help  of  the  students.  (1/4  =  2/8,  

¼  =  3/12,  2/8  =  3/12)  o. Remind  students  that  ¼,  2/8,  and  3/12  are  all  fractions,  which  are  part  of  a  whole.    

 3. Guided  practice  (We  do)  (10  min):  

a. Instruct  students  to  obtain  their  math  notebooks  and  pencil.  b. Provide  a  couple  of  examples  to  perform  with  the  students.    c. Perform  temperature  check  throughout  the  guided  practice.  (Thumbs  up  if  you  got  it  

right.  Thumbs  down  if  you  got  it  wrong)  d. Instruct  students  to  find  equivalent  fractions  that  they  see  on  the  given  picture.  e. Show  the  problem(s)  to  class.    f. Explain  to  students  what  the  task  is  (For  number  1  and  2:  first  find  equivalent  

fractions.  Second  shade  in  the  corresponding  picture.  Last  is  to  explain  why  the  fractions  are  equal.

have  in  the  first  picture?  What  about  the  second  picture?  This  picture  already  gave  you  a  fractional  part;  your  task  is  to  first  shade  in  the  corresponding  picture  for  the  first  fraction.)  

i. Ask  students  what  is  equivalent  to  3/4.  ii. Write  the  equivalent  fraction  that  students  provide.  iii. Ask  students  why  they  think  the  fractions  are  equal.  (How  did  you  figure  out
