Fast mental-math questions against the clock. Answer quickly and correctly to climb the levels and see your name on the leaderboard.
How to play
Log in through the Learning Portal first, the same code works for this, the Spelling Challenge, and everything else on the site.
Each level gives you 10 quick sums. Every correct answer is worth 1 point, and you have 10 seconds to answer each one.
Getting one wrong or running out of time doesn't skip you ahead, you keep going through all 10 questions in the level.
Score at least 8 points (8 out of 10 correct) to move to the next level, which brings slightly harder questions. Fewer than 8, and you restart that level with fresh questions.
You have 60 minutes of total play time per session, if you log out early, it picks up right where you left off next time.
Once your 60 minutes are used up, you'll need to wait 8 hours before playing again.
