The inner and outer wheels each contain a value in surd format. Multiply the inner and outer numbers in each segment to find 3 different surds. Turn the inner wheel to change the combinations and find the wheel setting that results in all three segments multiplying together to give the same surd.

I’ve made each resource twice - once designed to be just printed and once where the inner wheels can be cut out and pinned to the outer wheels using paper fasteners (solutions can be found in the “cutting version”)

My main motivation in making this resource was to present a rich problem solving activity for the topic in a visually novel format.
