Chalkboard Challenge is a problem solving game. It lasts 50 seconds.
Designed to help you:
- Compare values
- Make accurate estimations
How to play:
- An equation will appear on each card.
- Tap the card with the greater value.
- If they are equal, tap the equal button. [On computer, use arrow keys, left, right, and down for equal -- cards are left/right; on mobile, cards are top/bottom]
- Correctly answer 5 in a row to earn a 10 second bonus! [It looks like it just accumulates for every 5, not consecutive]
