Welcome to Mathematics MonsterWe have a full A-Z glossary of mathematical terms and hundreds of step-by-step lessons (all with tests, games, or interactive widgets). It's all free.
Free Teaching ResourcesAll of our lessons and glossary entries have multi-choice confirmatory tests, which are editable and printable.
To save paper, you can download the tests as Word documents for email attachments. You can even send the tests using messaging apps such as WhatsApp, Google Classroom, and Messenger.
Interactive Game on Prime Numbers
- You are the fish.
- Pop the bubbles with prime numbers to collect red hearts. You need five to win.
- If a bubble with a prime number reaches the top, you will lose a red heart.
- Avoid the bubbles with composite numbers (i.e., non-prime numbers). If you pop one, you will lose one of your three lives.
- Good luck!
- The fish moves to wherever you taptowards your mouse clicks. (Hint: The farther the distance, the faster it moves.)
