Let your students show their creative sides while putting the Order of Operations to use!
This document will guide your students through a project where they will solve an expression and display the problem and steps as different pieces of a mobil. Over the years, I've had more pizza slices, ice cream cones, and tornadoes turned in than I can count. But, the exciting part of this project is getting to see an artistic, creative side of your students that you might not see otherwise. I limit the examples I give so they can stretch their imaginations and be original.
Depending on the grade level you teach, you may want to assign the students very simple 3 to 4 step problems not involving exponents, or give them a 10 step expression with exponents, brackets, negative numbers, etc.
In my class, I assigned the problems on an individual basis so each student had a different problem at the challenge level appropriate for them.
I sent this project home to be completed over two weeks. When the projects were turned in, we displayed them in the hallways by hanging them from the ceiling so everyone could enjoy checking them out.
