Yes. StudyPug covers every Iowa Core Standards 1st grade math topic, from addition and subtraction within 20 to place value and shapes, so your child can find help for exactly what was assigned.

How long are the video lessons?

Most video lessons run between 5 and 15 minutes, covering one concept at a time. Short lessons make it easy to review a single topic without sitting through a full class session.

Is there a state test for 1st grade math in Iowa?

Iowa uses the ISASP assessment, but it is administered in grades 3 through 11. First grade is not an ISASP testing year, so there is no state standardized math test at this level.
