Will this help with my child's Grade 3 science homework?

Yes. StudyPug covers the Grade 3 science topics your child is working on in class, with step-by-step explanations and practice problems that match what Colorado schools teach.

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 and move on when they feel ready, without sitting through a long session.

Is there a Colorado state test for Grade 3 science?

Colorado's CMAS Science assessment is given in Grades 5, 8, and high school. Grade 3 is not a CMAS Science testing year, so there is no state science 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 access Grade 3 science lessons and practice at home or on the go from any device with a browser.

Can I try StudyPug before paying?

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