1. Answer to Question 1 (4 marks)

   1. The shape is cut into 2 equal parts and 1 part is coloured. So ¹⁄₂ (a half) is coloured. (1 mark)
   2. The shape is cut into 4 equal parts and 1 part is coloured. So ¹⁄₄ (a quarter) is coloured. (1 mark)
   3. There are 4 equal parts and 3 are coloured. So ³⁄₄ (three quarters) is coloured. (1 mark)
   4. A whole cut into quarters has 4 equal parts, so 4 quarters make a whole. (1 mark)

2. Answer to Question 2 (4 marks)

   1. Share 6 into 2 equal groups: 3 and 3. Half of 6 is 3. (1 mark)
   2. Share 14 into 2 equal groups: 7 and 7. Half of 14 is 7, because 7 + 7 = 14. (1 mark)
   3. Half of 20 is 10, because the double 10 + 10 = 20. (1 mark)
   4. No. Share 9 into 2 equal groups: 4 and 4 makes 8, and 1 is left over. 9 is an odd number, so its half is not a whole number. (1 mark: no and the 1 left over)

3. Answer to Question 3 (4 marks)

   1. Share 4 into 4 equal groups: one in each group. A quarter of 4 is 1. (1 mark)
   2. Half of 8 is 4, and half of 4 is 2. A quarter is half of a half, so a quarter of 8 is 2. (1 mark)
   3. Half of 16 is 8, and half of 8 is 4. So a quarter of 16 is 4. (1 mark)
   4. Half of 20 is 10, and half of 10 is 5. So a quarter of 20 is 5. Check: 5 + 5 + 5 + 5 = 20. (1 mark)

4. Answer to Question 4 (4 marks)

   1. Two pieces that are the same size are halves, so each piece is called a half. (1 mark)
   2. Four pieces that are the same size are quarters, so each piece is called a quarter. (1 mark)
   3. No. Dev has 2 pieces, but they are not the same size. Halves must be equal, so a big piece and a small piece are not halves. (1 mark: no and the pieces are unequal)
   4. Two quarters cover the same part as one half, so two quarters make a half. (1 mark)

5. Answer to Question 5 (4 marks)

   1. A quarter of 8 means 8 slices shared into 4 equal groups of 2. Nina eats 2 slices. (1 mark)
   2. Half of 8 means 8 slices shared into 2 equal groups of 4. Her brother eats 4 slices. (1 mark)
   3. Add the slices: 2 + 4 = 6 slices eaten. (1 mark)
   4. 8 − 6 = 2 slices are left. 2 slices out of 8 is the same as Nina's share, so it is a quarter of the cake. (1 mark for 2 slices and a quarter)
