Guess, Then Count

Goal: Make a sensible guess about how many things are in a group of up to 20, then count to check.

For parents: A sensible guess about how many, made before counting, is called an estimate. It does not have to be right: counting checks it. Start with groups of up to ten, then try up to twenty. Praise guesses that come closer, and never treat a guess as a mistake.

Do together

  1. Look, guess, count

    You need: Up to twenty large things of one kind, such as spoons, socks or toy blocks

    Put a group of up to ten on the table. Let your child look briefly and say about how many there are. Count together, moving each one aside as you say its number. Was the count more or fewer than the guess? Try a new group.

  2. Five to help

    You need: The same things and a sheet of paper

    Put five in a row on the paper as a helper group. Beside it, make a bigger heap of up to twenty. Ask whether the heap looks like about one five, two fives or more, then guess. Count the heap to check, and talk about how the helper group helped.

  3. The guessing tub

    You need: A clear plastic tub and the same large things

    While your child watches, put some of the things into the tub. Everyone says or draws a guess. Tip them out, line them up and count together. Whose guess was closest? Put in a different number and guess again. Notice whether the guesses come closer as you practise.

Talk about it

  • About how many do you think there are?
  • Was the count more or fewer than your guess?
  • How did the group of five help you guess?
