On Monday we worked through a quadratic visual pattern with blocks (blog post here), and so today we tried a harder one, again with linking cubes. Here’s a summary of their work:

My students used Desmos to find the equation since doing so algebraically is not in the 2P curriculum. In fact, determining the equation for a quadratic relation isn’t required in 2P at all, but since Desmos makes it so easy, we do it! I recreated their work in Desmos for the image in the summary above, but the blackboard work is theirs.

I think it’s time to clean my boards 😉

After taking up each group’s board as a class, we looked at this image to try and make connections between the geometric pattern and the equation we had found:
