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
547
466 ÷ 2 = 233
466
728 ÷ 2 = 364
728
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?
