- When asked “Why is this a triangle?”, a child says, "It has three angles" and counts them, pointing clearly to each vertex (point at the corner).
- When asked “How many angles, or corners, does this rectangle have?”, a child points to each and says “Four.”
Help your student become a(n) Corner (Angle) Recognizer
Activities and discussions challenge children to see corners (mathematical term: vertices) and angles (two sides with a common vertex) in shapes and be able to "abstract" them out of the shape.
