# Second Grade Math

### Second Grade Math Overview

Second grade marks the final primary steps that form the foundation on which students can build an increasingly complex understanding of mathematical concepts.

**In numbers and operations**, students will be using place value to represent the amounts in the tens and ones places so that they may begin comparing three digit numbers (CC.2.1.2.B.1). This knowledge of place value will then be applied to read, write, and skip count up to 1,000 (CC.2.1.2.B.2), as well as to add and subtract within 1,000 (CC.2.1.2.B.3).

**In algebraic concepts,**students will expand their ability to represent and solve addition and subtraction problems using numbers up to 100 (CC.2.2.2.A.1). They will also work on their ability to use mental strategies to quickly add and subtract within 20 (CC.2.2.A.2). Additionally, in preparation for the mastery of multiplication, students will work with equal groups of objects (CC.2.2.A.3).

**In geometry,**students will analyze and draw two and three dimensional shapes that have specified attributes (CC.2.3.2.A.1). They will also build upon the first grade work of partitioning shapes into halves and quarters while also adding the new fraction of partitioning shapes into thirds (CC.2.3.2.A.2).

**In data analysis and probability,**students will be tackling a variety of different skills. They will be be measuring and estimating units of length using appropriate tools (CC.2.4.2.A.1), telling and writing time to the nearest five minute increment using both analog and digital clocks (CC.2.4.2.A.2), and solving problems and making change using coins and paper currency with appropriate symbols (CC.2.4.2.A.3). Additionally, they will work on representing and interpreting data using line plots, picture graphs, and bar graphs (CC.2.4.2.A.4), and will apply their understanding of addition and subtraction to problems that involve length (CC.2.4.2.A.6).
