  2. 2. 1) a + a + a + a = 2) 3a x 2b = 3) c x c = 4) 4d + 2e - d + 3e = 5) 8f - 3g + 2f - 6g = 6) 5y - y = 7) Find the perimeter of this shape 8) b x b x b x b = 9) 3(2k + 3) = 10) a(a + 3) = a b
  3. 3. 1) a + a + a + a = 4a 2) 3a x 2b = 5ab 3) c x c = 2c 4) 4d + 2e - d + 3e = 3d + 5e 5) 8f - 3g + 2f - 6g = 10f - 3g 6) 5y - y = 5 7) Find the perimeter of this shape a 2 b 2 8) b x b x b x b = b 4 9) 3(2k + 3) = 6k + 3 10) a(a + 3) = a 2 + 3a a b
  4. 4. Memory games <ul><li>Do not use this as a power point presentation (i.e. do not go to view show), use it as it is now. </li></ul><ul><li>Click on the slide down the side to select the topic. </li></ul><ul><li>You can drag the blue squares away and put them at the side. If pupils find a pair leave the blue squares at the side. If they don’t then drag the blue squares back to where they were or press ctrl Z twice. </li></ul><ul><li>Please do not save any changes if prompted to as the blue squares will not be in the correct position if somebody else wants to use it. </li></ul>
