Each thing gets one number.

The last number is how many.

Read it: 1 number for each

5 ducks wait in a line. Touch each duck once and say 1 number for it. The last number you say is how many.

  1. Start at one end of 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.

Every duck gets 1 number. Skip one and you get too few; touch one twice and you get too many.

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

The last number is how many ducks there are, not the last duck's name.

Touch each one once. Say 1 number for each. The last number is how many.

Counting fast and touching a duck twice: 1, 2, 3, 3, 4.

Slow down. If a duck has a number, it does not get another.

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.

Count 7 dots in a line

Let's count these dots together. How many are there?

Start at the very first dot on the left. One.

Move one dot over. Two.

Keep going, one dot at a time. Three.

Next dot. Four.

We're halfway. Five.

Almost there. Six.

And the very last dot. Seven.
