    In an effort to have a strong math curriculum that is Common Core-aligned, Graham Hill requested and received a waiver to use the Bridges 2nd edition math curriculum for grades K -5. Montessori classrooms are mostly using a blend of Bridges and Montessori math works. Bridges has been rated as highly aligned with the Common Core Standards according to Ed Reports.*

    Bridges offers 8 units of study at each grade level. Each unit includes 20 lessons and takes approximately 4 weeks to complete. Each lesson takes a single class period. In addition to the main lesson of the day, students also work on their skills in 15- to 20-minute Number Corner exercises, many of which are games.

    Using this curriculum, students:

    • Play an active role in their own learning and in the classroom community 
    • Talk about math by sharing observations, explaining their thinking, and asking questions 
    • Use hands-on activities and a variety of math tools and visual models to understand how mathematical concepts work 
    • Build stamina for solving complex problems that require perseverance 
    • Play games in small groups to practice what they learn

If you have any additional questions or concerns, contact your child's teacher or Ruchi Sugimoto, our 3-5 Math Specialist ( or Ellen Kleyman, our K-2 math Specialist (

    * EdReports is a nonprofit organization dedicated to providing educators with a trusted resource for independent reviews of classroom curricula. Their rigorous process evaluates how closely curricula align to the Common Core State Standards using three main criteria: (1) Focus and Coherence, (2) Rigor and the Mathematical Practices, and (3) Instructional Supports and Other Usability Indicators.
