  3. 3 stages in any calculation 1. Concrete: using objects 2. Pictorial: drawing a picture 3. Abstract: writing a sum

  4. Addition 9 + 3 =

  5. 1. Concrete: use cubes for 9 and 3 3 cubes in the other egg box 9 cubes in one egg box

  6. Move cubes from one box to make 10 in the other box

  7. 2. Pictorial – showing working 9 + 3 = 12 1 2

  8. 3. Abstract – written down 9 + 3 = 12

  9. Subtraction 13 – 6 =

  10. 1. Concrete: use cubes Use cubes to show the first number (13)

  11. Move cubes to subtract the second number (6) from the ten

  12. Regroup: combine all the cubes
