What does Affix Architect teach?

Affix Architect is a reading game for 2nd grade – 5th grade that practises morphology (prefixes/suffixes/roots). 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. Affix Architect is playable in the browser with no ads and no signup. A free account (one child) saves progress and stars.
