Will this help with my child's Grade 8 math homework?

Yes. StudyPug covers every Ontario Grade 8 math strand, so your child can find a relevant lesson or worked example the moment they get stuck on homework involving fractions, equations, probability, or geometry.

How long are the video lessons?

Most video lessons run between 5 and 15 minutes, keeping each concept focused and easy to rewatch. Your child can pause, rewind, and move at their own pace without sitting through a full class replay.

Is there a provincial test for Grade 8 math in Ontario?

The EQAO assessment is administered in Grade 9 for math in Ontario, not Grade 8. Grade 8 is an important preparation year, so building strong skills now sets your child up well for that Grade 9 assessment.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, laptops, and desktop computers, so your child can practice Ontario Grade 8 math topics at home, on the go, or wherever it is most convenient.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can see the content before committing. If you subscribe and are not satisfied, a 30-day money-back guarantee is available - no lengthy cancellation process needed.
