Array builders

What is “Array builders”?

Array builders is a Kindergarten math skill in the Addition Alley region of the TernQuest map — add within 10, then within 20. It is aligned to California Common Core standard 2.OA.4. Children work through 24 grade-tagged questions at the apply level (applying the idea), and Pip the tern offers a hint — never the answer — when they get stuck.

How does it unlock?

Skills on the map unlock in order: finishing the skill before this one with a mastery score of 60 or more opens array builders. A grown-up can also assign it directly from the dashboard, and teachers can assign it to a whole class with a join code.
