The Number Combination Race Game Mats are based on the Floor Race concept found in the Developing Number Concepts Using Unifix Cubes book by Kathy Richardson.
The objective of the game is for players to complete their game mat first by creating different combinations for the selected number using Unifix Cubes. This helps students and children to learn to decompose numbers.
The game is played in two stages. In the first stage, the players take turns rolling dice or using a spinner to determine the length of the first part of each column. Each player rolls or spins six times. The same number can be used more than once.
In the second stage, players use a dice or spinner to complete their columns on the game mat. A different colored Unifix cube is used for the second stage of the game.
There are 8 game mats. Number combinations covered are from numbers 3 to 10. Corresponding worksheets are included for children to record their number combinations.
There are also 4 spinners which can be used instead of dice.
