            Learning Objective :
                                                                                                   5   6   21   30
            Practising division by playing games.
                                                                                                   2   4   5   8
            What You Need :
                                                                                                   3   9   23   27
            Paper, pencils, fact family strips
                                                                                                   1   4   5   20
            Procedure :
                                                                                                   3   5   1   15
            Step 1 :  Cut  paper  and  make  several  (20–30)  “fact  family
                                                                                                   3   6   15   18
                       strips” that contain four numbers— three numbers in
                       a fact family and one number that doesn’t belong to                         2   3   5   10

                       the fact family.                                                            7   8   56   71

                       For example ; In a fact family strip, the numbers are
                       5, 8, 3 and 40. Three of them i.e. 5, 8 and 40 are a fact family because


                       5 × 8 = 40, 8 × 5 = 40, 40 ÷ 5 = 8, 40 ÷ 8 = 5 and 3 doesn’t belong to
                       the fact family.


                       Write  down  the  fact  family  and  ask  your  partner  to  tell  you  the
                       multiplication and division facts that can be made with the numbers.

            Step2 :  You have a group of four such numbers. Your partner has to correctly

                       identify the number that doesn’t belong to the fact family and then state
                       a division fact using the numbers in the fact family.


            Step3 :  Set  a  timer  for  2  minutes  and  begin  working  through  as  many  “fact
                       family strips” as possible in two minutes.

                       At  the  end  of  two  minutes,  count  the  number  of  strips  in  which  your

                       partner  correctly  identified  the  fact  family  and  stated  a  division  fact
                       using the numbers.

            Step4 :  Now, try to beat your partner's record.


                       For example if your partner identified 8 fact families in 2 minutes, try to
                       identify 9 or 10 fact families in 2 minutes.

                       Shorten the time to one minute and repeat the process.
