Mathematics (Grade 1)

Navigation

Mathematics instruction in Norfolk Public Schools is guided by the Massachusetts Curriculum Framework for Mathematics, including the Standards for Mathematical Practice. Our goal is to help students develop a strong foundation in mathematical thinking, problem-solving, and communication. Students explore real-world problems, share their reasoning, and learn multiple strategies for solving tasks. Lessons balance whole-class instruction, small-group work, independent practice, and time for reflection. A variety of tools—such as manipulatives, visual models, and digital resources—support learning and deepen understanding.

In First Grade, students build fluency with addition and subtraction within 20, strengthen their understanding of place value (tens and ones), and begin solving problems with larger numbers. They also explore measurement using standard units and investigate the attributes of shapes, laying the groundwork for later geometry concepts.

Core Resources

Amplify Math

Amplify Math is built around an exciting, hands-on, and problem-solving approach to help your child truly understand math, rather than just memorize facts. Your student won't just sit and listen; they'll be active participants who start with an engaging, curiosity-sparking problem and collaborate with classmates to figure out the solutions, sharing their "brilliant mathematical ideas" in a supportive environment. The program blends hands-on activities with manipulatives (physical objects) and digital tools, focusing on the process of thinking and building confidence so that your child sees themselves as a capable mathematician from day one, with daily, fun game-like activities to reinforce what they've learned.
