Quadratic Formula

In grade 10 we’ve been working on parabolas all year. In our first lap we did factoring and expanding with algebra tiles. In Lap 2 we did all things factored. Now that we’re in lap 3 we did vertex form, and also derived the quadratic formula.

we sing the quadratic formula to the tune of pop goes the weasel. Here’s a youtube video

We’re connecting back to all we know about quadratics, and finding the axis of symmetry, the vertex, and the y intercept as well.

Students are enjoying working together at the walls “thinking classroom” style. It gets us up and moving, and collaborating. At this time of year it’s nice to see that there are so many people in the room who are getting confident and able to help others out. We’ve come a long way since February!

Pretty soon we’ll be solving word problems!
