  9. 1 9 202 - 39 = 2 0 2 - 3 9 1 1 1 6 3

  10. Have a go…. 672 – 61 = 304 - 25 = 456 - 81 =

  11. TU x TU Long multiplication Year 6

  12. Today we are learning to; • Multiply a 2 digit number by another 2 digit number using the long multiplication method we used last week. • For example “How do we calculate 23 x 13?”

  13. 72 x 12 =

  14. 72 x 12=

  15. 72 x 12=

  16. 72 x 12= 0 “Remember to add a zero!”

  17. 72 x 12=

  18. 72 x 12=

  19. 72 x 12= “Next, add the numbers together!”

  20. 72 x 12=

  21. 72 x 12=

  22. 72 x 12=

  23. So, 72 x 12= 864

  24. 68 x 23=

  25. 68 x 23=

  26. 68 x 23=

  27. 68 x 23= Mmmm, what do I do now?

  28. 68 x 23= 0 “Aha! Add the zero!”

  29. 68 x 23=

  30. 68 x 23= 1

  31. 68 x 23= Add the numbers together!

  32. 68 x 23= 4

  33. 68 x 23= 6 4

  34. 68 x 23= 5 6 4

  35. 68 x 23= 1 5 6 4

  36. So, 68 x 23 = 1,564

  37. 52 x 12=

  38. 52 x 12=

  39. 52 x 12=

  40. 52 x 12= 0 Mmmmm… What do I do now? “Add the zero!”

  41. 52 x 12= 2 0

  42. 52 x 12= 5 2 0

  43. 52 x 12= “Add the numbers together!”

  44. 52 x 12=

  45. 52 x 12=

  46. 52 x 12=

  47. So, 52 x 12= 624

  48. Division 363 ÷ 3 = 121 1 2 1 First, build your stairs! Then, house your numbers… 3 3 6 3

  49. Division & carrying 345 ÷ 3 = 115 1 1 5 First, build your stairs! Then, house your numbers… 3 3 4 5 1

  50. Division & remainders 337 ÷ 3 = 111 r 1 1 1 2 First, build your stairs! Then, house your numbers… r 1 3 3 3 7
