# Speedy Eight

2 players. You need a dice, two colours, a printed grid.

Before you begin: Each player writes a list of 8 numbers between 1 and 50 for the other player to find.

To begin: roll the dice to decide who is the active player first. The highest goes first.

To play: The active player looks for any of their eight numbers, using three numbers as described above, and colours them in on the grid. Once a tile has been used it cannot be used again.

The other player rolls the dice until they roll a six. When they roll a six, they become the active player. The first person to find all eight of their numbers wins.

# Collaborative games with the number grids

- Print a number grid. Write down the numbers 1 – 49. See how many you can find on the grid without repeating any square on the grid.
- Print a number grid. Write down the first 10 numbers cards shown above. See how many can be found such that the squares used form an unbroken chain, joined by sides and not overlapping.
