1 Addition & Subtraction Add Plus More than Subtract Difference Take away Altogether Minus Less than +-

2 Addition & Subtraction +- 15 23 8 How do they link? 15 + 8 = 23 8 + 15 = 23 23 – 8 = 15 23 – 15 = 8

3 Addition & Subtraction +- H T U 2 7 4 3 4 8 + 6 2 2 1 H T U 6 7 11 2 1 4 3 4 8 – 3 7 6

4 Multiplication & Division Times Product Groups of Lots of Divided by Multiply Share equally x ÷ Factor Multiple

5 Multiplication & Division x÷ 27 9 3 How do they link? 9 x 3 = 27 3 x 9 = 27 27 ÷ 3 = 9 27 ÷ 9 = 3

6 Multiplication & Division x÷........ 4 x 5 = 20 5 x 4 = 20 18 ÷ 3= 6 18 ÷ 6= 3

7 Multiplication & Division x÷ 66 x206 1020060 3 18 total26078 26 x 13 260 + 78 = 338 42 ÷ 6 = ? I know that 6 x 7 = 42 So the answer is 7.
