The picture below shows an interactive display that I created in my classroom for my students. As
they completed the “May the Fours Be With You” activity, I asked them to check
their expressions with me.

Then, I asked the students to add their expressions to the posters displayed around the room. (The posters in the photo are a polished example of the students’ responses that I reworked in order to share this photo with you. However, these are the expressions they created.)

This became an excellent activity– one that totally had the students engaged! They all wanted to create an expression for numbers that did not yet have an expression written on the poster. I left the posters up for a few weeks so that the students could continue to add to them.

The activity also made a great fast finisher challenge. As an added bonus, the students enjoyed checking the other students’ responses to be sure that they did in fact equal the number at the top of the poster. This provided a rich opportunity to review the order of operations and how to simplify expressions.
