This Representing Multiplication Activity is a very unique way to get your kids engaged and will make their learning stick. Students will have to represent a multiplication fact or a word problem in all 6 ways Array, Repeated Addition, Equal Groups, Area Model, Number Line, and Skip Counting. They however will have to create at least one representation incorrectly. When they or their group is done, then another student or another group must combine them and determine which representation is incorrect. Then they must justify why. This really gets kids thinking at a higher level and beefs up their math talk skills. It is amazing to see the "tricks" your students can come up with for the incorrect representations. If they can create, then identify which answer is wrong then the tricks on the STAAR test will not affect them.
I print off the right and wrong cards on the same color of paper. I print 6 copies of the right cards and 1 copy of the wrong cards. I then put the cards into bags labeled A-F. In each bag I put 5 right cards and one wrong card. Make sure you have all six ways to represent a multiplication fact in each bag. Then I give students a word problem. They must work with their group to create the multiplication representation on their card that matches their word problem. One person in the group will do the representation wrong. As a table they need to keep this a secret. Once every table is done they will walk around as a group to the other table’s word problems and representations. They will need to read the word problem then look at the representations. Then they will debate as a group which representation is wrong. Once they have come up with an answers they will record their answer on their recording sheet. After all groups have visited each table we will then talk as a whole group about which representation at each table was incorrect.
Differentiation: There are endless way to differentiate this activity. You can have more wrong cards at each group. This can also be used in small group. You can also make up other word problems. I have also played this game where there was one representation done, no word problem, (lets say an array). Students then must identify they multiplication equation then create the other representations along with one representation being incorrect. This activity promotes math talk.
