Before you start
This is a strategic game of addition. It is played with 2 players. It offers the opportunity to think strategically by considering several moves in advance, and practise working with addition at the same time!
What your child needs to know and do
Your child needs to have strategies for solving problems with addition.
What to do next
Play the game!
Students slide the shared counter across several adjacent numbers, adding them up as you go to make a 'running' (or cumulative) total. The goal is to be the first player to make the final slide so that the chosen target is reached exactly. Making the total go above the target loses you the game.
How to play
Player 1 chooses a target to reach. This is the total both players try to make.
Player 2 places their counter on the game board over one of the numbers and says that number.
Player 1 moves the same counter in any direction along a line segment to a neighbouring number and announces the total of the two numbers.
Player 2 moves the same counter to cover a neighbouring number, adds on that number, and announces the 'running' total of the three numbers.
Players take it in turns to slide the counter to cover a neighbouring number and to add that number to the 'running' total.
Players must move when it is their turn.
No 'jumping' is allowed.
