Here is an interactive game to help you learn about even and odd numbers.
- You are the fish.
- Pop the bubbles with even numbers to collect points.
- Every correct bubble you pop earns you a green tick. If you can get five green ticks, you'll earn 1,000 bonus points! However, when a bubble with an even number reaches the top without being popped, you will lose a green tick.
- Avoid the bubbles with odd numbers. If you pop one, you will lose one of your three lives and your green ticks will return to zero.
- The lower you pop a correct bubble the more score you score.
- Good luck!
- The fish moves towards your clicks. (Hint: The farther the distance, the faster it moves.)
A Formula to Generate Even Numbers
The formula below generates even numbers:
If k takes a whole number (1, 2, 3...), then n will always be even.
k = 0 ∴ n = 2k = 2 × 0 = 0
k = 1 ∴ n = 2k = 2 × 1 = 2
k = 2 ∴ n = 2k = 2 × 2 = 4
k = 3 ∴ n = 2k = 2 × 3 = 6
k = 4 ∴ n = 2k = 2 × 4 = 8
