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

Yes. StudyPug covers the topics Kansas 3rd graders work on in class, so your child can find a relevant lesson or practice problem right when they need it for homework.

How long are the video lessons?

Most video lessons run between 5 and 15 minutes, covering one focused concept at a time. Your child can pause, rewind, and rewatch as many times as needed to fully understand the material.

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

Kansas uses the KAP Science assessment, but it is administered in grades 5, 8, and 11 - not 3rd grade. StudyPug still helps build the science foundations students need in later assessed years.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and computers, so your child can access lessons and practice problems at home, on the go, or anywhere they have an internet connection.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can explore the content before subscribing. There is also a 30-day money-back guarantee if the subscription is not the right fit for your family.
