# Math

• In 2nd Grade Math, there are 8 Modules/Units.  Below, are the titles of each Module and a brief explanation of what they are about.  For in-depth information, such as Chapter Summary, Focus Standards, and Foundational Standards, click on the individual link (left hand side)(coming soon) you desire to receive information on.

1.  Sums and Differences to 20
This module sets the foundation for students to master the sums and differences to 20 and to subsequently apply these skills to fluently add one-digit to two-digit numbers at least through 100.

2.  Relate Addition and Subtraction to Length Units
Students learn to measure and estimate using standard units for length and solve measurement word problems involving addition and subtraction of length.

3.  Place Value, Counting and Comparison of Numbers to 1000
Students extend their understanding of base-ten notation and apply their understanding of place value to count and compare numbers to 1000.

4.  Addition and Subtraction to 200 with Word Problems to 100
Students apply their work with place value units to add and subtract within 200 moving from concrete to pictorial to abstract.

5.  Addition and Subtraction of Numbers 10 - 1000 with Word Problems to 100
Students again use place value strategies, manipulatives, and math drawings to extend their conceptual understanding of the addition and subtraction algorithms to numbers within 1000.

6.  Foundations of Multiplication and Division
students extend their understanding of a unit to build the foundation for multiplication and division wherein any number, not just powers of ten, can be a unit.

7.  Problem Solving with Length, Money, and Data
Module 7 provides another opportunity for students to practice their algorithms and problem-solving skills with perhaps the most wellknown, interesting units of all: dollars, dimes, and pennies.

8.  Time, Shapes, and Fractions as Equal Parts of Shapes
Students finish Grade 2 by describing and analyzing shapes in terms of their sides and angles. In Module 8, students investigate, describe, and reason about the composition and decomposition of shapes to form other shapes.
