This task was created in collaboration with Prof. Dor Abrahamson (University of California, Berkeley) and is based on his research. According to his work, physical experience helps kids understand the idea of ratio, which is crucial for further understanding of fractions, percentages etc.

In this game, kids help Tenrec board a ship leaving for a faraway island. The first level lets the players experiment with and feel the patterns of their hand movements while trying to make Tenrec smile. The second level provides more visual tips to help players reflect on their physical experience. The last level introduces numbers that help players associate their previous experience with the standard numerical form of proportion and ratio.

— Intuitive understanding of length ratio
— Linear dependence
— Coordination and hand movement to understand ratio
— Physical interpretation of ratio
— 1/1, ½, ⅓ ratio
