Yes. StudyPug covers every Oklahoma Academic Standards 1st grade math topic, from addition and subtraction within 20 to place value and geometry, so your child can find help on the exact concept their teacher assigned.

How long are the video lessons?

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

Oklahoma's OSTP Math assessments are given in grades 3 through 8 and in high school. 1st grade is not an OSTP testing year, but building strong foundations now prepares students for those later assessments.
