2-D shapes
Recognise and name common 2-D shapes (circles, triangles, rectangles including squares)
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
A 2-D shape is flat. A circle has one continuous curved edge and no corners. A triangle has three straight sides and three corners. A rectangle has four straight sides and four square corners. A square is a special rectangle with four equal sides. A shape keeps its name when it is bigger, smaller, turned, or rotated.
Spend 10 minutes naming large parent-drawn circles, triangles, rectangles, and squares, then turn and resize the drawings and find every triangle in a mixed set.

Check understanding
- Name a triangle, circle, rectangle, and square when shown them
- Identify a shape correctly regardless of its size or orientation
- Pick out all the triangles from a mixed set of shapes
“Can your child point to shapes around the house — like a clock, a window, or a pizza — and correctly name whether each is a circle, triangle, rectangle, or square?”
