'Division Rules' printed from https://nrich.maths.org/
Begin by deciding on your divisor. Then create your first dividend and complete the calculation.
Then try another calculation! Remember to record your results. You could use a table like the one below.
Table for recording results for a divisor of 2:
Calculation |
Whole number answer |
Remainder of 1 |
269 ÷ 2 = 134 r1 |
|
269 |
547 ÷ 2 = 273 r1 |
|

466 ÷ 2 = 233 |

Look at the dividends which result in a whole number answer.
Can you spot any similarities?
Can this help you to conjecture a rule about which other dividends will have a whole number answer when divided by 2?
Test your rule for other dividends.
Can you spot a rule for the dividends which give a remainder of 1 when divided by 2?
