Set the amount of Juice A and Juice B with the − and + buttons (or drag a glass up to fill it, down to empty it) until their ratio matches the target — any equivalent amounts work — then press Check.

3D math game · Best for grades 5-6
Ratio Mixer places students at a smoothie bar with two juice glasses. The goal is to pour Juice A and Juice B in a target ratio — and discover that 1:2, 2:4, and 3:6 all produce the same drink. The act of adjusting amounts until the ratio clicks makes equivalence feel concrete rather than symbolic.
Ratio Mixer builds the core understanding that a ratio describes a relationship between two quantities, not a fixed pair of numbers. Students discover that multiplying both parts by the same factor preserves the ratio — the foundation for proportional reasoning in grades 5 and 6.
For a target of 1:2, pouring 3 units of Juice A and 6 units of Juice B is accepted because 3:6 simplifies to 1:2. Students see that the flavour — the ratio — stays the same regardless of total volume.
Students often fix one amount and only adjust the other, which rarely keeps the ratio correct. The game teaches that both quantities must scale together, correcting the common belief that only one side of a ratio can change.
Use it for individual practice, paired work, or a short class demonstration before worksheets.
