Dividing by Chunking (3 digit by 1 digit)

  1. 1. Dividing a 3 Digit Number by a 1 Digit Number For Example: 882 ÷ 6 By Chunking For more maths help & free games related to this, visit: www.makemymathsbetter.com
  2. 2. When “chunking” I think of the question as referring to a certain number of sweets (in this case 882) that needs to be shared between a certain number of children (in this case 6). I then ask myself, how many sweets can I give to each child? 6 882
  3. 3. In this example, I’ll start by imagining that I’m giving each child 100 sweets. This is 6 x 100 = 600 6 882
  4. 4. In this example, I’ll start by imagining that I’m giving each child 100 sweets. This is 6 x 100 = 600 This amount is placed under the 882 6 882 600 6 x 100
  5. 5. To find the number of sweets remaining, I then subtract 600 from 882 6 882 600 6 x 100
  6. 6. To find the number of sweets remaining, I then subtract 600 from 882 Which is 282 6 882 - 600 282 6 x 100
  7. 7. From the remaining 282 “sweets”, I then imagine that I am giving 40 to each child. This is 6 x 40 = 240 6 882 - 600 282 6 x 100
  8. 8. From the remaining 282 “sweets”, I then imagine that I am giving 40 to each child. This is 6 x 40 = 240 This amount is placed under the 282 6 882 - 600 282 240 6 x 100 6 x 40
  9. 9. To find the number of sweets remaining, I then subtract 240 from 282 6 882 - 600 282 240 6 x 100 6 x 40
  10. 10. To find the number of sweets remaining, I then subtract 240 from 282 Which is 42 6 882 - 600 282 - 240 42 6 x 100 6 x 40
  11. 11. From the remaining 42 “sweets”, I then imagine that I am giving 7 to each child. This is 6 x 7 = 42 6 882 - 600 282 - 240 42 6 x 100 6 x 40
  12. 12. From the remaining 42 “sweets”, I then imagine that I am giving 7 to each child. This is 6 x 7 = 42 This amount is placed under the 42 6 882 - 600 282 - 240 42 42 6 x 100 6 x 40 6x7
  13. 13. To find the number of sweets remaining, I then subtract 42 from 42 6 882 - 600 282 - 240 42 42 6 x 100 6 x 40 6x7
  14. 14. To find the number of sweets remaining, I then subtract 42 from 42 Which leaves zero 6 882 - 600 282 - 240 42 - 42 0 6 x 100 6 x 40 6x7
  15. 15. Altogether, each child has been given 100 + 40 + 7 sweets 6 882 - 600 282 - 240 42 - 42 0 6 x 100 6 x 40 6x7
  16. 16. Altogether, each child has been given 100 + 40 + 7 sweets So, 882 ÷ 6 = 147 6 882 - 600 282 - 240 42 - 42 0 6 x 100 6 x 40 6x7 147
