Doggie Doubles
A chance to practice basic facts to 12 and identify the result of a double.
Play The Doubles
An understanding of mathematical recording is required and a realisation that a relationship exists between addition and subtraction.
Cycle Race
Using the language of doubles and halves and the sequencing of numbers up to 50. Children should be encouraged to count forwards and backwards.


Social Skills
The games are all designed to be played with a partner learning to take turns. Children should be encouraged to vary the rules provided they are agreed on and adhered to throughout the game.


Problem Solving Skills
Game 4 requires children to understand an equation in result unknown, change unknown and start unknown formats. Make up word stories to fit each type of equation. Encourage children to make up their own word stories.

Numeracy Skills
Doubles to 20 are prerequisites for the two times tables and provide key knowledge for the development of further strategies. Sequencing numbers up to 50 are also used in game 5.

Oral Language
When using mathematical equations it is important that it is accompanied by meaningful contexts and language that the children understand and can use themselves. Equations can very quickly become meaningless. Children will need to develop the language of doubles and halves. Children should be encouraged to verbalise their thinking as they play the games.
