About this skill
Compare each angle with a right angle (like the corner of a book).
How to teach it
- Go on a shape hunt around the house.
- Count sides and corners out loud.
- Use real objects to show 3D solids.
Mistakes to watch for
- Confusing a square and a rectangle (a square is a special rectangle).
- Calling a 3D solid by a 2D name.
