While learning multiplication in 3rd grade we teach students how to use arrays as a strategy. Rather than drawing arrays and solving problems on our own I created problem cards for students to work on with a partner. They read the problem together and used color tiles to create an array (the first number tells how many rows, the second number tells how many columns) and the product is the total number of tiles. Students work and create rectangles and then come up with a related fact from the fact family. Using math talk this is a great activity for active engagement.
