WHICH ONE?

WHICH ONE? is a Grade 5 customary-measurement game that mixes conversion and comparison questions. Each player receives a card marked either “Convert!” or “Compare!” and answers independently before exchanging cards for checking. Correct conversion cards earn one point, while correct comparison cards earn two, making both unit relationships and relative size part of the game.

Use it for small-group review when students are working with customary units of length, weight, and volume. Because the question type changes from round to round, students must decide whether to compute an equivalent measure or compare two quantities.
