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

Yes. StudyPug covers the topics Colorado 2nd graders study in class, so your child can find a matching lesson, review the concept, and work through practice problems to finish their homework with confidence.

How long are the video lessons for 2nd grade science?

Most video lessons run just a few minutes, so they are easy to fit into an afternoon routine. Your child can pause, rewind, and rewatch any lesson as many times as needed to understand a concept.

Is there a Colorado state test for 2nd grade science?

Colorado administers the CMAS science assessment, but it is given at grades 5, 8, and in high school - not at 2nd grade. StudyPug still helps your child build the science foundations they will need in later tested years.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, laptops, and desktop computers, so your child can study at home, in the car, or wherever it is most convenient for your family.

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 you are not satisfied.
