Game teaching guide

What children will practise

Find sums of two numbers up to 10 by counting on, and see that swapping the order gives the same total, in line with indicator ค 1.1 ป.1/4 on finding the unknown in addition number sentences.

What's in the worksheet

6 questions, multiple choice with 3 options each, all within 1 of the answer - 3 + 4 = 7, 5 + 2 = 7 - 4 + 4 = 8 (a double) - 2 + 7 = 9 (quicker counting on from 7) - 5 + 5 = 10 (two hands of fingers)

How to use it in class

Use early in the addition unit once children can count on. 5 minutes. - Play solo so everyone thinks for themselves; fingers or counters are fine - After question 5, ask "Is it quicker to start counting from 2 or from 7?" to teach counting on from the larger number - If many are one too high, show counting on along a number line without saying the starting number again - Play it linked to a class and the scores go into the class gradebook.

Common sticking points

- Answering one too many, e.g. 3 + 4 = 8, by counting the starting number again; 8 is one of the options - In question 5, counting on 7 steps from 2 and slipping, giving 8 or 10 - In question 6, answering 11 or 9 when fingers are miscounted
