Math standards connections
Each Focusplay math activity practices one grade-level skill. This page groups the 212 math activities by the Common Core State Standards for Mathematics domain they practice, so you can see where Focusplay fits next to your core curriculum.
How to read this page
- Domains follow the Common Core State Standards for Mathematics (CCSSM), which California adopted as the California Common Core State Standards for Mathematics.
- Our team mapped each activity to the domain it practices. This is not a third-party alignment review, and Focusplay is a practice supplement, not a core curriculum.
- Brain, attention, creativity and language games are not listed here.
- Need a mapping at the individual standard level (for example 3.OA.C.7) or to your state's standards? Email hello@focusplay.ai.
