1. Answer to Question 1 (4 marks)

   1. Count the groups in the picture, one at a time: there are 4 groups. (1 mark)
   2. Each group holds the same number of objects: 3 in each group. (1 mark)
   3. Add one 3 for each of the 4 groups: 3 + 3 + 3 + 3. (1 mark)
   4. Count in 3s: 3, 6, 9, 12. There are 12 in all. (1 mark)

2. Answer to Question 2 (4 marks)

   1. Double means add the number to itself: 6 + 6 = 12. (1 mark)
   2. 9 + 9 = 18. Tip: double 10 is 20, and 1 less twice is 18. (1 mark)
   3. Half means 2 equal groups. 6 + 6 = 12, so half of 12 is 6. (1 mark)
   4. 10 + 10 = 20, so half of 20 is 10. (1 mark)

3. Answer to Question 3 (4 marks)

   1. This counts in 2s: 2, 4, 6, 8, 10. (1 mark)
   2. This counts in 5s: 5, 10, 15, 20. (1 mark)
   3. This counts in 10s: 10, 20, 30, 40. (1 mark)
   4. Each hand has 5 fingers. Count in 5s for 3 hands: 5, 10, 15. So there are 15 fingers. (1 mark)

4. Answer to Question 4 (4 marks)

   1. There are 4 plates with 3 sweets on each. Count in 3s: 3, 6, 9, 12. There are 12 sweets. (1 mark)
   2. Share 12 sweets between 4 children one at a time: each gets 3, because 3 + 3 + 3 + 3 = 12. (1 mark)
   3. Share 12 between 2 children: each gets 6, because 6 + 6 = 12. (1 mark)
   4. A child in the group of 2 gets 6 and a child in the group of 4 gets 3. 6 is more than 3, so a child in the group of 2 gets more. (1 mark)

5. Answer to Question 5 (4 marks)

   1. Each box has 5 cars. Count in 5s for 3 boxes: 5, 10, 15. There are 15 cars. (1 mark)
   2. Add the 5 cars in the bag: 15 + 5 = 20 cars in all. (1 mark)
   3. Half of 20 is 10, because 10 + 10 = 20. So 10 cars are sold. (1 mark)
   4. Take the sold cars away: 20 − 10 = 10 cars left, the other half. (1 mark)

Total : 20 marks
