WorksheetsWhat this unit covers
The starting point is telling a triangle, enclosed by three straight lines, from a quadrilateral, enclosed by four. Attention then turns to right angles, so that squares, rectangles and right triangles can be picked out, and the unit ends with Perimeter of Shapes.
Children who treat any pointed corner as a triangle also pick figures whose lines do not join up and figures with curved sides. In Perimeter of Shapes, side lengths that are not printed go unsupplied and only the given numbers get added, so the answer is short by two sides.
Sorting shapes by concrete clues, the number of sides and how sharp the corners are, is what is new in this unit. Triangles and quadrilaterals are told apart using the eye for grouping built in Types of Shapes, and this way of looking leads into Triangles in grade 3, where side length becomes the sorting rule.

A pointed corner facing sideways is enough for a child to say, "that's not a triangle." It's a sign they've learned shape names by overall look rather than by their properties. Here's how to teach children to tell shapes apart by the number and length of their sides, in order from grade 2 through grade 4.
