Will this help with my child's 1st grade math homework?

Yes. StudyPug covers every Connecticut Core Standards topic for 1st grade math, including word problems, place value, and telling time, so your child can find help on exactly what was assigned that day.

How long are the video lessons?

Most video lessons run between 5 and 15 minutes, focused on one concept at a time. Your child can pause, rewind, and rewatch as many times as needed before moving on to practice problems.

Is there a Connecticut state test for 1st grade math?

Connecticut's main standardized assessments are not administered in 1st grade. Formal state testing under the Connecticut Smarter Balanced assessment typically begins in 3rd grade, so 1st grade results are tracked by the classroom rather than a statewide exam.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and desktop computers, so your child can practice 1st grade math at home, in the car, or anywhere with an internet connection.

Can I try StudyPug before paying?

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