The ideas in this lesson are taken from Division 2 ebook. Only a few examples of each problem type are shown; you should make more problems of each kind for the student. Division as repeated subtraction - introduction to long division

Example. Bag 771 apples so there are 3 apples in one bag. How many bags
are needed? You can start by putting 3 apples to one bag, which leaves you 768 apples. Then for each bag you subtract 3 apples and keep counting the bags you use, until you hit zero apples.
So total needed 200 + 50 + 7 = 257 bags to bag all the apples. And it all went even - no apples left over! In other words, 771 ÷ 3 = 257. |

Example 4. You have 686 apples. If you put
8 apples in one bag, how many bags will you need?
In other words, 686 ÷ 8 = _______, R 6. |
|
Example 5. It won't matter even if you do the subtracting in
smaller steps. Compare the two ways
|
1. Fill in the bags/fruits at each step of bagging.
a. Bag 610 apples; 5 apples in each bag.
|
b. Bag 852 kiwis; 3 kiwis in each bag.
|
| e. Bag 162 pears; 6 pears in each bag. f. Bag 495 cherries; 9 cherries in each bag. g. Bag 429 mangos; 3 mangos in each bag. |
h. Bag 164 pineapples; 2 pineapples in each bag. i. Bag 4613 guavas; 7 guavas in each bag. j. Bag 1098 bananas; 9 in each bag. |
2. Do the divisions using the repeated subtraction. You can still think in terms of bagging fruit if it helps you. Also, you are encouraged to even try doing it mentally. Note: some of these divisions are even, some have remainder.
| a. 555 ÷ 3
b. 750 ÷ 5 c. 257 ÷ 5 d. 464 ÷ 8 |
m. 472 ÷ 5
n. 340 ÷ 2 o. 537 ÷ 9 p. 994 ÷ 7 |
q. 670 ÷ 5
r. 750 ÷ 6 s. 238 ÷ 9 t. 294 ÷ 7 |
