Mathematics (Grade 3)

Navigation

Mathematics instruction in Norfolk Public Schools helps students develop deeper conceptual understanding while applying math to meaningful contexts. Students learn to see connections among concepts, use visual models, and explain their reasoning in multiple ways. Instruction is responsive to student needs and includes whole-class lessons, small-group instruction, independent practice, and time for sharing and reflection.

In Third Grade, students build understanding of multiplication and division within 100, laying the foundation for future work with proportional reasoning. They develop an initial understanding of fractions as numbers and begin to compare and represent them. Students also explore two-dimensional shapes, and study rectangular arrays and area as ways to connect geometry and multiplication.

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.
