Reedhop Fractions
Reedhop Fractions is a fractions maths game that plays in the browser on phones, tablets and computers, for one player. It has a daily challenge, the same for everyone that day.
Hop a frog along a number line from 0 to 2 with fraction jump cards and land exactly on the flower pad. Before crossing you choose how finely the line is marked, and every hop must end on a mark, so the coarsest marking that works is a common denominator. There are 60 crossings and a daily pond that is the same for everyone.
How to play
- Tap a jump card to hop that far along the line
- Land exactly on the flower. Hops must end on a mark: pick finer marks if needed
- The coarsest marks that work earn the most stars. Undo takes a hop back
The game shows these steps as you play, the first time.
Controls
- Tap a card to hop, tap a marking to re-mark the line
- Keys 1 to 7 play cards, up and down change the marks, Backspace or Z undoes, R restarts
Tips
- To add a quarter and a third you need twelfths, because 12 is the smallest number that both 4 and 3 divide into.
- A pad shows a question mark until the line is marked finely enough to reach it, so try finer marks to read the pads.
- Changing the marks sends the frog back to the bank, so pick the marking first and then plan every hop on it.
How are the stars earned?
Three stars for crossing on the coarsest marking that works, which the game's solver finds for every pond, and two for a finer marking that still works. A hop into open water costs one star, but never takes the crossing below one.
What do the back cards do?
From crossing 31 some cards hop the frog back toward the bank by their fraction. They help reach a pad that the forward cards overshoot, and like every card each one can be played only once per crossing.
