  1. To divide larger numbers I can divide by chunking

  2. If you had a large bag of sweets how would you share them? Consider 450 sweets ÷ 30 children You can see that there are a lot more than 30 sweets so the children would get more than one each. Could we give them 10 each? Yes! 10 x 30 = 300 so we have enough.

  3. Have we shared them all? No we still have some left to share. 450 – 300 = 150 So we have 150 sweets left to share next. Can we give them 10 each again? No! 10 x 30=300 we don’t have enough. Can we give them 5 each? Yes! 5 x 30 = 150

  4. Let’s picture it.

  5. How many sweets does each child have?

  6. So 450 ÷ 30 = 15 How we write our working out. 15 30 ) 450 -300 (10x30) 150 -150 (5x30) 0

  7. Now try 340 ÷ 20 = 17 20 ) 340 -200 (10x20) 140 -100 (5x20) 40 -40 (2x20) 0

  8. Now try these  320 ÷ 20 680 ÷ 40 600 ÷ 40 840 ÷ 70 700 ÷ 50 420 ÷ 30 960 ÷ 60 350 ÷ 25 182 ÷ 13 276 ÷ 22 224 ÷ 16 253 ÷ 11 240 ÷ 15 552 ÷ 23 • 900 ÷36 • 512÷ 32 • 697 ÷ 41 • 854 ÷ 61 • 624 ÷ 52 1170 ÷ 45 1428 ÷ 34
