Social Skills
The games are all designed to be played with a partner learning to take turns. Decisions on how many throws of the dice are allowed on each turn should be decided and adhered to throughout the game.

Problem Solving Skills
Game 2 requires logic and reasoning. Which is the best way to use the numbers? On first playing children are unlikely to think in this way but with subsequent games children begin to use these strategies. DON’T TELL

Numeracy Skills
Children are learning the initial stages of place value. This involves understanding the recording of two digit numbers in a base ten system. The teens numbers are the basis of the system and critical to the development of mathematical thinking. Why is 10 so important?

Oral Language
