More game ideas:
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.
- Print a number grid. Write down the numbers 1 – 50. 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 do not overlap.
