Teaching ideas

Warm up:

• Explore number of corners on each shape
• Sort shapes into those with 5 corners or more and those with fewer than 5 corners.

Thinking:

• Add "and 5 sides" to the label. Which shapes belong in the circle?
• Count the number of sides and corners on each shape. What do you notice?

Puzzle:

• If the label reads "has two right angles" which shapes belong in the circle?
