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

Yes. StudyPug covers every DC 1st grade math topic, from adding and subtracting within 20 to telling time and working with shapes, so your child can get unstuck right when they need help.

How long are the video lessons?

Most video lessons run between 5 and 15 minutes, keeping things short enough to hold a first grader's attention. Each lesson focuses on one concept, so your child can rewatch any part as many times as needed.

Is there a DC test for 1st grade math in the District of Columbia?

DC CAPE assessments are administered in select grades. First grade is not a primary tested year, so there is no high-stakes DC standardized math test at this level. Daily classwork and teacher assessments guide progress in 1st grade.

Can my child use StudyPug on a tablet or phone?

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

Can I try StudyPug before paying?
