I use this project when I start my multiplication unit to teach repeated addition, groups of, commutative property, and arrays. You could also replace one with a multiplication word problem and picture.

2D Shape Properties Matching Activity - For use as a matching game or a worksheet, a set of 8 2D shape image cards with matching property descriptions. A great way to assess children’s knowledge of shape properties. Also available for 3D shapes.

Gemstone outlined shapes. The children made some brilliant patterns with the coloured gems and talked about the properties of the shape as they created the outlines.
