Geometry to think along with

What your child practises

• Reflection and symmetry: finding mirror points on grid paper and spotting lines of symmetry.
• Perimeter and area: adding all the way around or multiplying rows by squares – for rectangles, squares and triangles, and for shapes made of two rectangles.
• Solids: counting the corners, edges and faces of a cube, counting cube buildings and checking cube nets.
• Position and measures: right angles, parallel and perpendicular lines, radius and diameter, scale and sliding shapes.

How the videos work

Each video first shows an example on the board. Then Theo asks a similar question, the video pauses and your child types an answer. Finally the question is solved step by step.

Geometry is easy to try at home: grid paper, a ruler, building blocks or a dice help your child explore what they have just seen.
