The goal of the mathematics curriculum is to teach children that mathematics is an integral part of everyday life. Second graders explore the relationships and patterns among numbers and discover how different operations affect numbers. They also gain a conceptual understanding of place value. They continue to improve their computation skills as well as increase their repertoire of problem solving skills. Throughout the year, students explore geometric figures, fractions, money, and tools for measurement.
Problem Solving Recognize, describe, extend, and create patterns
 Recognize and classify by attributes
 Use manipulatives to investigate and solve new mathematical situations
 Use problem solving strategies such as looking for patterns, drawing a picture, tallying, etc.
 Appreciate that there are often myriad ways to solve a given problem
Reasoning Use addition and subtraction to complete or create a number pattern
 Identify and describe what comes next in a pattern (counting by 2s, 5s , 10s or exploring patterns in a 100 chart)
 Explore number families (2+3=5; 3 + 2=5; and 52=3; 53=2)
 Use doubles and doubles plus one
 Explain why an answer is correct or incorrect and whether or not the answer is reasonable
Communication Discuss mathematical concepts and relationships
 Use objects, pictures and numbers to illustrate mathematical concepts
 Solve problems in two different ways and share written solutions
Connections
 Explore and discuss the relationship of addition and subtraction
 Connect mathematical applications (i.e. graphs, tables, and other math skills) to social studies, science, and children’s literature
 Connect mathematics to the real world
Number Sense and Numeration Count and write numbers 1100
 Count by ones, fives, and tens up to 100
 Order a set of numbers from smallest to largest
 Name the whole number immediately before or after a given twodigit number
 Compare twodigit numbers and identify which is more or less
 Use a place value model to represent numbers up to one hundred
Concepts of Whole Number Operations and Computation  Recognize and develop a sense of whole numbers, onetoone correspondence, odd and even numbers and ordinal numbers
 Use and understand place value (hundreds, tens, ones)
 Explore the “commutative” property
 Use concrete, pictorial, and verbal representations of operations
 Have knowledge of addition and subtraction facts through 18
 Add numbers with and without regrouping
 Explore the concept of subtraction with regrouping (exchanging)
 Use estimation and mental computation to solve problems
Fractions Recognize fractional parts of the whole (i.e. one out of 3 parts is shaded, 3 out of 4 parts is shaded, etc.)
 Recognize fractions when written numerically (1/2, 1/3, and 1/4)
Geometry and Spatial Sense Define the terms “point” and “line”
 Define, describe, and classify two and three dimensional figures
 Recognize and create symmetrical shapes
 Recognize and describe geometric shapes and structures in the environment
Measurement Select appropriate tools for measuring length, time, and money
 Explore perimeter, area, volume, weight, and temperature
 Develop an understanding of how to measure using standard and nonstandard units
 Understand the concept of hour and minute
 Understand the 5 minute intervals on a clock
 Compare analog and digital clocks
 Identify coins and match equivalent sets of coins
 Explore the concept of decimals through the use of money
 Explore the concept of making change
Data Analysis and Probability
 Make and read graphs and charts representing sets of data
 Explore simple probability
 Pose questions, gather and interpret data
