How StudyPug Helps Rhode Island 1st Graders

Every lesson on StudyPug is built around one clear topic. Your child watches a short video, then tries practice problems right away. If they get stuck, they can replay the lesson as many times as they need. This approach works whether your child is keeping up with class, catching up after a tough week, or getting ahead before the next unit.

All content is aligned to Rhode Island Math Standards, so every lesson matches what Rhode Island teachers are covering in the classroom. Parents can track progress and see exactly which topics their child has worked on.

Getting Ready for RICAS Math

Rhode Island uses the RICAS assessment starting in Grade 3. The skills your child builds in 1st grade — number sense, place value, addition, and subtraction — form the foundation for everything tested on RICAS. Starting strong in 1st grade gives students a real advantage when testing begins.
