Using Cubes for Problem Solving

This week Mrs. Doyle and I had a great chance to see some CGI problem solving in action. KIPP DC has done a lot of work this year to push their students thinking and problem solving skills. One big takeaway we had is that students need cubes to directly model the problem. Understanding the context of the problem and being able to show what is happening is crucial for student understanding.

The cubes should be readily available and in towers of ten, of all the same color. We keep them in towers of ten to help students with base ten thinking. When they always start with groups of ten, they are much more likely to use base ten strategies to make counting and operations more efficient.

Cubes should always be out and being used during story problem time for K-2 and can be easily stored and hassle free!

As you can see, 1 black cube got mixed into the blue cube box. You have to really work with students on keeping them organized and putting them back into tens at the end of the lesson, but that can definitely do it!
