I don't know why, but I don't do this as nearly enough as I should. Using key concepts makes me think about things differently and allows me to come up with ideas that I normally wouldn't have thought of.
REFLECTION: We had already explored properties of triangles. I used this station and the concept of reflection to get kids to think about what they have learnt.
CHANGE: Student had to change shapes using an original shape or by combining other shapes.
FUNCTION: How can I find a shape that has all these properties?
