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

Yes. StudyPug covers every Illinois 1st grade math topic, including addition and subtraction within 20, place value, and telling time, so your child can find help for exactly what their teacher assigned.

How long are the video lessons?

Most video lessons are short and focused, typically a few minutes each, so a 1st grader can watch one lesson at a time without losing concentration before moving on to practice problems.

Is there an Illinois state test for 1st grade math?

Illinois state standardized testing under the IAR begins in 3rd grade, so 1st grade is not an assessed year. StudyPug still helps students build a strong foundation for the years ahead.

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.
