Standards covered

Every worksheet shows its standard code in the footer. This page lists what each grade covers, unit by unit.

Math, Reading, Writing, Spelling, Phonics, and Vocabulary follow the Common Core State Standards. Math units are taught in the order used by widely adopted Common Core programs.
Science follows the Next Generation Science Standards (NGSS).
Social Studies follows the C3 Framework for Social Studies State Standards.
Major work. Math skills in the clusters that get the most class time are starred in the app.
Limits. Reading, Science, and Social Studies are practice to go alongside class, not a full year's program, and a few standards that do not suit a worksheet are not covered. States that do not use Common Core teach some topics in a different order.
