An interactive whiteboard resource to demonstrate sorting groups of factors using a venn diagram. This resource could be useful when teaching highest common factors.
Use the arrows to change the number to generate factors for. Drag and drop the tiles to the correct position on the venn diagram. They will illuminate green when correctly placed and red when incorrectly placed.
A similar interactive whiteboard resource focussing on multiples rather than factors.
Another factor based resource but one that demonstrates prime factor trees.
