Double digit multiplication

So far this week in math, students reviewed multiplication arrays , cuisenaire  rods, and 2 digit by 1 digit multiplication with and without regrouping. 

The next step is 2 digit by 2 digit!! 😁 We will spend the remainder of this week and we'll continue into next week working through this new concept. I plan on showing students a couple different visuals , or mnemonic devices, on how to go about solving these multiplication problems. Make sure to ask them which way they like! (Partial product window box, many zoos many animals , bow tie method, turtle head).
