What does Castle Knock teach?

Castle Knock is a math game for Kindergarten – 5th grade that practises number rules + angles & power as numbers. 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. Castle Knock is playable in the browser with no ads and no signup. A free account (one child) saves progress and stars.
