Before you play

Game teaching guide

What children will practise

Recognise Thai 1, 2, 5 and 10 baht coins, total several coins of one kind, match number words to numerals, and subtract within 10.

What's in the worksheet

4 rounds, a matching game with 4 pairs each - The two-tone coin with 10 baht; the silver coin with a milled edge with 5 baht - Two 5-baht coins with 10 baht; four 2-baht coins with 8 baht - เจ็ด with 7; เก้า with 9 - 8 - 5 with 3; 10 - 4 with 6

How to use it in class

Use with real or play coins. 6-7 minutes. - Give each group a set of real coins before round 1 so children can feel the size, colour and edge - For round 2, count coin by coin, e.g. 2, 4, 6, 8, rather than multiplying - If many miss round 1, compare a real 2-baht coin, which today is gold-coloured, not silver - Play it linked to a class and the scores go into the class gradebook.

Common sticking points

- In round 1, today's 2-baht coin is gold-coloured, so children holding real coins cannot find the thin silver one and match by elimination - In round 1, swapping the 1-baht and 5-baht coins, which are both silver - In round 2, matching four 2-baht coins with 6 baht after a slip counting in twos

Play together first, then build on it with a worksheet for the same level.
