Reflection: Gradual Release Multiplication arrays - Section 3: Concept development

As you can see in my reflection video, this lesson went very well.

I must admit, that this morning before this lesson, I was dreading it. In the past, the Associative Property and arrays was a mess of a lesson for me. In this lesson today, I made sure to focus on the vocabulary as well as explicitly make connections between what was happening numerically and visually with the area model.  I think this lesson would have tanked if either of those were left out.  With out the numerical connections, students are simply drawing arrays and finding partial products.  I felt like I did a great job at teaching this lesson with the focus of 4.OA.5 being the properties of operations.   I would have liked to have an extra half an hour with my students and continue with other examples, but I knew the vocabulary fold-able would take some time. Because I think math vocabulary is so important,  I knew the second part of the lesson would be cut short.

Associative Property ROCKED their world!
