Supporting students to geometrically reason and then communicate their thinking is always a challenging task, and a somewhat intimidating one from the student’s perspective. So, when Eddie Woo shared some of Naoki Inaba’s Area Mazes at a keynote presentation, I was excited about the potential for students in my classroom. If you haven’t got it already, there is a brilliant little book called The Original Area Mazes, which have 100 problems and worked solutions.
Here are some I’ve made myself, as I struggled to find any online that included triangles, instead of rectangles.
Edit: I’ve also included some that are similar to Area Mazes, but closer to the style seen in Geometry Snacks.
- Find the exact value for the purple area.
- The area of the circle is the same as the area surrounding it. What is the shortest distance from the edge of the circle to the edge of the square?
- If the pink and white area is equal, what is the distance shown?
- Find the shaded area. The purple point is the centre of the square.
