• Second Grade Mathematics Curriculum Modules

Summarized from A Story Of Units

Module 1: Sums and Differences to 20
Students will work on mastery of basic addition and subtraction facts to 20. They will learn to represent and solve word problems using addition and subtraction.

Module 2: Addition and Subtraction of Length Units
Focus is on metric measurement (centimeters and meters) of length to help prepare students for place value. Students will learn to measure and solve measurement word problems using addition and subtraction.

Module 3: Place Value, Counting and Comparison of Numbers 1 to 1,000
Students will extend their understanding of base-10 and apply it to their understanding of place value to count and compare numbers to 1,000. The students will learn to use number disks to model larger numbers.

Module 4: Addition and Subtraction Within 200 with Word Problems to 100
Students will apply their work with place value to add and subtract within 200 moving from concrete to pictorial to abstract. They will be challenged to apply their knowledge to one- and two-step word problems. Fluency of addition and subtraction within 100 will be reinforced.

Module 5: Addition and Subtraction Within 1,000 with Word Problems to 100
Students use place value strategies, manipulatives, and drawings to extend their conceptual understanding of addition and subtraction to numbers within 1,000. Fluency is reinforced through daily work to solve one- and two-step word problems. Students learn to use place value reasoning to explain why their strategies work.

Module 6: Foundations of Multiplication and Division
Students extend their knowledge of a “unit” to build the foundation for multiplication and division. Focus is on making equal groups of something that can be counted.

Module 7: Problem Solving with Length, Money, and Data
Students practice their algorithms and problems solving skills with dollars, dimes, and pennies. Measuring and estimating length is reviewed using units from both the customary and metric systems. Students will also represent data given in money and length measurement by using picture graphs, bar graphs and line plots.

Module 8: Time, Shapes, and Fractions as Equal Parts of Shapes
Students will investigate, describe, and reason about the composition and decomposition of shapes to form other shapes. The foundation for understanding area, volume, congruence, similarity, and symmetry for later grades will begin to develop. Students will also tell time and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m
