Game teaching guide

What children will practise

Review adding and subtracting within 10, including subtracting to zero, and use the link between addition and subtraction to check answers.

What's in the worksheet

6 questions, multiple choice with 3 options each, 3 additions and 3 subtractions - 8 - 3 = 5 - 10 - 7 = 3 (because 7 + 3 = 10) - 7 - 7 = 0 - 3 + 6 = 9 - 2 + 8 = 10

How to use it in class

Use as a quick warm-up after subtraction has been taught. 4-5 minutes. - Play solo, then check the gradebook for children who miss only the subtractions - For question 3, check by adding back: does 3 + 7 make 10? - If many mix up the signs, circle + and - in different colours before working - Play it linked to a class and the scores go into the class gradebook.

Common sticking points

- In questions 1 and 3, adding instead of subtracting because the set alternates operations; the sums are not offered, so these children usually pick the nearest option - In question 5, choosing 7, thinking taking a number from itself leaves it unchanged - In question 1, answering 6 by counting 8 itself when counting back
