Mathematics (Grade 4)

Navigation

Mathematics instruction in Norfolk Public Schools emphasizes both procedural fluency and deep understanding. Students are encouraged to make connections across topics, choose efficient strategies, and explain their reasoning. Through collaborative discussion, hands-on tasks, and real-world problem-solving, students grow as confident mathematical thinkers.

In Fourth Grade, students build fluency with multi-digit multiplication and gain understanding of division with multi-digit numbers. They develop a stronger sense of fractions—exploring equivalence, adding and subtracting fractions with like denominators, and multiplying fractions by whole numbers. Students also analyze and classify geometric figures based on their properties, strengthening their reasoning and vocabulary in geometry.

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.
