Quick tips

• Check with multiplication. If 4 envelopes hold 22 each, 4 × 22 should give back the total of 88.
• Add before you share. When two people give, pool the money first, then divide once.
• Leftovers are smaller than the group. With 5 children, the leftover is always 0 to 4 coins. More than that and everyone could get one more.
• Move half the gap. To even out 42 and 22, move 10, not 20: moving the whole gap just flips who has more.
• Count parts, not people. Two older children at 2 parts and one younger at 1 part make 5 parts. Find one part first.
