Introduction
(5 minutes)
- Call students to the rug, and instruct them to form a triangle with their fingers by joining pointer fingers and thumbs. Tell them to repeat after you, "Triangle."
- Ask students to call out other shapes that they know, for example squares, circles and rectangles. Let them know that today they will think about what makes a triangle the same as and different from other shapes.
