# Doubling using Finger Patterns

### Purpose:

• To develop children’s ability to double numbers 1–20.

• Nothing

### How to play:

• The game starts with two players facing each other.
• Each player puts their hands behind their backs.
• Player one calls out a number between 1–5.
• Each player holds up the finger pattern for that number.
• Player one calls “double”.
• The players press their finger pattern to the finger pattern of their partner.
• Both players call out the total number.
• The game is repeated using all the numbers 1–5.

### Variations:

• Double numbers 6 -10. When working with numbers bigger than 5 it is best to show a hand of 5 then the additional fingers. For example, 6 would be shown as 5 fingers on one hand plus one finger on the other hand.
• A solo doubling activity can be done with a mirror. Your child calls out a number and holds up that amount of fingers. Your child rests their finger tips on the mirror and says the number of the fingers he/she can see altogether.
