This game utilizes the part of the brain that reacts to ratios.
Specific neurons in this region will react to specific ratios such as 1/3 or 4/5.
This newly identified area can be an area upon which fractional understanding can be built.

Hit the ratios in order from small to large. Items used are shown below.
For the bars the more green the larger the amount. For the squares the more purple the larger the amount.
Use the arrow keys to move and the spacebar to fire.
Good luck.
