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

Yes. StudyPug covers every 1st grade math topic in the North Dakota curriculum, from addition and subtraction within 20 to telling time and basic shapes, so your child can get help on exactly what was assigned in class.

How long are the video lessons?

Most video lessons are short and focused, typically running a few minutes each, so a 1st grader can watch one topic at a time without losing focus. Each lesson targets a single concept from the ND Content Standards.

Is there a state test for 1st grade math in North Dakota?

North Dakota's statewide NDSA assessment is given in grades 3 through 8 and grade 11, so 1st grade is not a tested year. StudyPug still helps students build the strong foundation they will need when testing begins in 3rd 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 topics at home, in the car, or wherever is convenient.

Can I try StudyPug before paying?

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