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

Yes. StudyPug covers every California 1st grade math topic, including word problems, place value, and telling time, so your child can find a lesson that matches exactly what they brought home.

How long are the video lessons?

Most video lessons run between 5 and 15 minutes, making them easy to fit into an after-school routine. Your child can pause, rewind, and rewatch any lesson as many times as needed.

Is there a California state test for 1st grade math?

California's CAASPP summative assessments are given in grades 3 through 8, so 1st graders do not sit a statewide test. StudyPug still helps build the foundations that assessments in later grades will measure.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and computers, so your child can practice at home, in the car, or anywhere else with an internet connection.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can see how it works before subscribing. Every paid plan also comes with a 30-day money-back guarantee if it is not the right fit.
