What does Binary Builders teach?

Binary Builders is a coding game for 3rd grade – 5th grade that practises binary / number systems. Like every TernQuest game it is tied to a skill on the curriculum map (state standards — Common Core, NGSS, CSTA and History–Social Science, PK–5), and Pip the tern gives hints, never answers.

Is it free?

Yes. Binary Builders is playable in the browser with no ads and no signup. A free account (one child) saves progress and stars.
