ACS delivers a standards-based program in mathematics, guided by the Common Core standards. In the elementary school, Everyday Math is used as a primary resource for mathematics instruction. ## Common Core

Consistent with many high performing international private schools and public schools in the United States, ACS has adopted the Common Core Standards as the baseline learning objectives for K-10 instruction in Math and in English Language Arts.

## Everyday Math

Aligned to the Common Core Standards, the primary resource for Elementary Math instruction is the Everyday Math program. Click here for a parent overview.
