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 counter"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.
