Build One Whole

Build One Whole is a Grade 3 fraction activity that uses fraction bars to compose a complete whole. Students draw fraction pieces, arrange them into strips equal to 1, and trade equivalent pieces with other players when they need a different combination. The exchanges make equivalence practical because students must decide what can fairly replace the piece they are giving away.

Use it for independent or small-group work when students are learning that the same whole can be composed in many different ways. Listen for how they justify equivalent trades and how they know their combined pieces total exactly 1. Generate teacher-ready lesson support for Build One Whole with a free Find a Math Game account.
