Here's a game to play with an adult!
Have you noticed that some very long numbers are very big whilst other very long numbers are small? Can you think of an example of each?
Here's a game where you can test your skill at putting small numbers into the right order - it's not as easy as it sounds!
How do you play?
You'll need an adult to play with.
You'll also need a copy of the game board and two different coloured pencils.
Decide who goes first.
Take turns to choose a number from the grid and mark it on the spiral. Make sure you know where $0$ and where $1$ is!
Keep taking turns until one of you has marked three numbers next to each other.
Does it matter who goes first?
Can you work out a winning strategy?
