Read it: Touch each duck once

Maya has 5 ducks at the pond. Touch each duck once. The last number is how many.

1. Start at the first duck in the line.
2. Touch a duck, say a number, move on: 1, 2, 3, 4, 5.
3. The last number you said is how many: 5 ducks.

Each duck gets 1 number. Skip one and the total is too small; touch one twice and it is too big.

Going along the line in order stops you counting a duck twice.

5 is not the last duck's name. It is how many ducks there are.

Say 1 number for each duck. The last number is how many.

You touch each duck in a line once and say 1 number for each. The last number you say is 7. How many ducks are in the line? — 7. The last number you say names the whole line, not the duck at the end — so there are 7 ducks.
