Will this help with my child's 2nd grade math homework?

Yes. StudyPug covers every topic in the California 2nd grade math curriculum, including word problems, place value, measurement, and geometry, so your child can find help on exactly what was assigned in class.

How long are the video lessons?

Most video lessons are short and focused, typically a few minutes each, so your child can watch one topic at a time without losing attention. They can pause, rewind, and rewatch as many times as needed.

Is there a California state test for 2nd grade math?

California administers the CAASPP assessments, but statewide summative math testing begins at 3rd grade. 2nd graders are not part of the CAASPP summative window, so there is no state math test at this grade level.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and computers, so your child can practice 2nd grade math at home, in the car, or wherever is most convenient for your family.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can explore the content before subscribing. Every paid plan also comes with a 30-day money-back guarantee if you are not satisfied.
