## Reflection: Rigor Multiplying by 2-Digit Numbers (Day 1) - Section 5: Work It Out

I LOVE four square posters. They are a fun, quick and differentiated tool to check for understanding. AND you students can have fun and get creative with them.

Don't get locked in with what I've designed, change it to fit your needs and what you want to check the students for understanding.

It is also great work to put up and display. There are times I like them to use the same problem and find different ways to model it and sometimes it is a bunch of different problems.

Be creative. Even ask students what they want to put in the boxes. I also have students ask does it matter where things go and I tell them no because I want it to be their poster not mine.
