Game teaching guide

What children will practise

Name the number of sides of polygons (indicator ค 2.2 ป.2/1), link 3D shapes to everyday objects, count the edges of solids, and review the 2 and 5 tables.

What's in the worksheet

4 matching questions - Triangle 3 sides, pentagon 5, hexagon 6 - Cube 12 edges, square-based pyramid 8 edges, sphere no edges - Cylinder with a drinks can, cone with a party hat - 2 × 7 = 14 and 5 × 6 = 30

How to use it in class

Use in a geometry lesson when real objects or shape models are available, 6-8 minutes, team mode. - For edges, give each team a real box or cube and count edges by touching each one - After the objects question, have pupils find cylinders or spheres in the room - Q4 is times tables, not shapes; mention it beforehand - Play it linked to the class to record results in the mark book

Common sticking points

- Counting 4 or 8 edges on a cube by counting one face or the corners. Touch each edge and mark it with a sticker - Puzzled by the cylinder's 2 edges because they are curved, not straight. Run a finger round the rim of a real can. Some books do not count curved edges; if a pupil says a cylinder has none, accept the reasoning and explain that this game counts the 2 curved edges - Counting only the 4 base edges of the square-based pyramid
