The next lesson continues to explore the
3 times button candy array cards the 3rd Grader and I
made in the last post. (view post)
In preparation for our lesson, I attached a new card to each of the previously made array cards. My plan is to work with the array cards and their related facts
( the Commutative Property of Multiplication).
First, we skipped counted by threes and sixes.
"Yes, I noticed that they are the same size."
"How can you tell?" I asked.
"Well, if you lay one on top of the other you can see they are the same size."
"Yes, they are the same size or we could say they are conquent in shape and contain the same area."

We summarized our thoughts by filling in the Venn Diagram in the "how they are the same".We then glued the arrays on the worksheet, and I asked her why she glued them in different directions on the worksheet.
Lastly, the student cut out and glued (on the blue side of the card) the new arrays for each of the related fact multiplication equations.
