This game helps students practise identifying which number is bigger.
To play both players choose a number card (available up to 50).
They compare their numbers and the student with the greater number takes a coutner "alien" for his/her spaceship (place it onto their 10 frame).
If someone draws a meteor card then they must return 2 aliens.
The winner is the person who reaches 10 aliens/counters first, or the one with the most aliens when time is up.
