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

Yes. StudyPug covers every 1st grade Oregon math topic, including addition and subtraction within 20, place value, telling time, and shapes. Your child can find the exact lesson they need and work through practice problems right away.

How long are the video lessons?

Most video lessons run between five and fifteen minutes, so they fit easily into a homework session. Your child can pause, rewind, and re-watch any part as many times as needed until the concept clicks.

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

Oregon state assessments for math begin in 3rd grade, so 1st graders do not sit a formal state math test. StudyPug still helps students build a strong foundation for the assessments they will face in later grades.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and computers, so your child can practice 1st grade math at home, on the go, or anywhere with an internet connection.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can see the content before committing. There is also a 30-day money-back guarantee, giving you time to make sure it is the right fit for your child.
