Grade 2 Mathematics


Second Grade Overview

The big ideas for second grade students will focus on more sophisticated work in addition and subtraction of whole numbers, and begin conceptual development of multiplication and division, grounded in contexts and modeled using concrete objects. Teachers will emphasize the inverse relationships between addition and subtraction, and multiplication and division. Students will use strategies and algorithms to compute using whole numbers. Students should be able to demonstrate fluency with addition and subtraction facts up to 10 + 10 by the end of the second grade. Simple ideas about fractions are introduced. In geometry, students will continue to learn about geometric shapes and their elements.
