For examplle, some studentts may use theirr pictoriaal representation n and see 4 + 1 == 5 and theen use the 5 triangles embedded d in the 9 too make a ten. NOTES ON MEANS MULTIPLE M OF ACTION AND EXPRESSION N: Having students act out number stories is a great way to provid de math‐they‐ can‐seee. This may help p your students who aree hearing impairred. It also providees visual and kinesthetic learnerrs an oppoortunity to engaage in the lesson n using thheir preferred sttyle of learning. Lesson 1 1: Date: © 20144 Common Core, Inc.
