Will this help with my child's 1st grade math homework?

Yes. StudyPug covers every Ohio 1st grade math topic - addition and subtraction, place value, measurement, time, and shapes - so your child can find help for any homework question right when they need it.

How long are the video lessons?

Most video lessons run between a few minutes and about ten minutes, keeping things short enough to hold a first grader's attention while still walking through each concept step by step with clear examples.

Is there an Ohio state test for 1st grade math?

Ohio does not administer a statewide standardized math test in 1st grade. State testing under Ohio's system begins in later grades, so 1st grade is a classroom-assessment year focused on building core skills.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and computers, so your child can watch lessons and do practice problems at home, on the go, or wherever learning fits into your family's day.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can see how it works before committing. All paid plans also come with a 30-day money-back guarantee, so there is no risk in getting started.
