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

Yes. StudyPug covers the exact topics in Missouri's 3rd grade science curriculum, so your child can watch a short video lesson and work through practice problems for whatever came home that night.

How long are the video lessons?

Most video lessons are between 5 and 15 minutes long, so they fit easily into homework time. Your child can pause, rewind, and rewatch any part of a lesson as many times as needed.

Is there a Missouri state test for 3rd grade science?

Missouri administers the MAP Science assessment in grades 5 and 8, not grade 3. StudyPug still helps 3rd graders build the foundational science knowledge they will need in those tested years ahead.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, laptops, and desktop computers. Your child can switch between devices without losing their progress, making it easy to study at home or on the go.

Can I try StudyPug before paying?

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

About Grade 3 Missouri science

Missouri 3rd grade science follows the Missouri Learning Standards, which are organized around life science, earth and space science, physical science, and engineering and technology concepts. Students at this level explore how living things grow and survive, patterns in weather and the environment, forces and motion, and how people design solutions to problems. StudyPug provides video lessons and practice problems that match what Missouri classrooms cover, so your child can keep up or get ahead all year.
