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

Yes. StudyPug covers every 1st grade math topic taught in Idaho classrooms, including addition and subtraction within 20, place value, telling time, and shapes, so your child can get unstuck quickly.

How long are the video lessons?

Most video lessons run between 5 and 15 minutes, so they fit into a busy evening. Your child can pause, rewind, and re-watch any lesson as many times as they need before moving on.

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

The ISAT assesses Idaho students in math starting in 3rd grade, so 1st graders do not sit a state math exam. StudyPug still helps build the strong foundation your child will need in the years ahead.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and desktop computers, so your child can practice 1st grade math at home or on the go without needing any special equipment.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can see the content before committing, and every paid plan comes with a 30-day money-back guarantee if it is not the right fit.
