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

Yes. StudyPug covers every 1st grade math topic in the SD Content Standards, including addition and subtraction within 20, place value, telling time, and shapes, so your child can get help the moment they are stuck.

How long are the video lessons for 1st grade math?

Most video lessons are short and focused, typically a few minutes each, so young learners can follow along without losing attention. Each lesson targets one concept at a time, making it easy to find exactly what your child needs.

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

South Dakota assesses students through the SD Assessment program, but 1st grade is not a tested grade year. Formal statewide math assessments are administered in later grades, so 1st grade focuses on building a strong foundation.

Yes. StudyPug works on tablets, phones, and computers, so your child can practice 1st grade math at home, in the car, or anywhere else. No special app download is required to get started.
