A dot image gives students the opportunity to see connections between operations and visualize the properties of operations by counting a set of dots in many ways.

It was great to see students find so many ways to break down a multiplication problem. The visuals of the dots in equal groups allowed them to see many different smaller groups. This gave students at all levels access to the problem. Ms. Gray provided scaffolding to keep the conversation moving but never inserted her own thinking into the discussion. With such high engagement I would imagine that these students are extremely fluent with multiplication concepts. This is also evident in the variety of diagrams in the student work.

Would this work as a way to introduce math talks and to also assess student abilities to problem solve?

I like the way you are careful not to tell them if they are correct or incorrect in their thinking or solving. Also, the journal is a fabulous idea for assessing students! Thank you.
