How to Demystify Math With These 7 Algebra Activities

by BrainNinjasWP

If you are avoiding algebra activities in your math class, we're here to help. We have several lessons and activities that can take the mystery out of your introductory algebra lessons and get you feelling confident about teaching it. We've got activities for patterns and algebra that you can use with any resources! Come have a read today!

When we hear that we have to do algebra activities, the fear is real. Algebra is this haunting reminder of high school. When I was becoming a teacher, I didn’t want my negative experiences with math to influence how I taught it or, more importantly, how my students learned it.

In university, I was put in a “special” math class designed for education students who needed to refine their math skills. Truthfully, it was for us creatives who didn’t take enough math during high school and university. At first, I was scared of the class, but as the class progressed, I realized how lucky I was to be there. Not only did I get over my fear of math, I learned how to break down math concepts in so many different ways that I could teach it to any student. Come learn some of the ways to break down introductory algebra with these algebra activities.
