Grade 1 · Unit 6: Shape

Shapes, symmetry and tiles

Put shapes together, fold them and fit them.

Tangram pieces can make many pictures.

Shape puzzles

Puzzle pieces can make animals, boats and houses. Shapes can be put together and taken apart. Let us explore!

Making new shapes

Put two triangles together: they can make a square. Cut a square in half: you get two triangles. Shapes can make other shapes.

Round and round

A circle has a centre point. Every point on its edge is the same distance from the centre. An oval is round too, but it is longer one way.

Mirror halves

This house has symmetry. Draw the missing half like a mirror picture. Find symmetry in leaves, faces and alpana designs.

No gaps!

Floor tiles fit with no gaps and no overlaps. This is called tessellation. Turn a square a quarter turn: it still looks the same! It looks the same 4 times in a full turn.
