Knowledge of mathematics is essential to be a productive member of a technological society. It is the mission of South Windsor Public Schools to provide a mathematics curriculum that will encourage students to shape information into knowledge and experience into understanding. Our philosophy is that students learn mathematics best by doing mathematics. It is the role of the teacher to guide students in constructing their own mathematical understanding. Teachers will implement curriculum and plan activities that will guide and support students as they investigate, analyze and achieve. As a result of this guidance, students will develop an appreciation of the value of mathematics, gain confidence in their ability to use mathematics, and become mathematical problem solvers. Students will also develop their ability to communicate and reason mathematically. All students are expected to master mathematics according to their greatest potential.
The major goals of the South Windsor Public Schools mathematics curriculum are to:
Ensure high expectations and access to meaningful mathematics learning for every student.
Ensure implementation of the Standards for Mathematical Practice to develop the processes and proficiencies in mathematics.
Implement a curriculum that is aligned to national and state standards while incorporating 21st century skills and technologies, resulting in relevant and meaningful instruction and high student achievement.
Utilize data-driven decision making based on universal screens, benchmarks and formative assessments to inform instruction and improve student learning.
To ensure instructional equity among all students.
The Mathematics curriculum encourages the use of the following Mathematical Practices:
Make sense of problems and persevere in solving them
Reason abstractly and quantitatively
Construct viable arguments and critique the reasoning of others
Model with mathematics
Use appropriate tools strategically
Attend to precision
Look for and make use of structure
Look for and express regularity in repeated reasoning
Math Unit Overview
The district is using the San Francisco math curriculum as a core resource. A description of each of the units is provided below. These units tie to the skills and student outcomes outlined in the progress report overview.
Unit 2.1
Grouping Objects
Unit 2.1
Grouping Objects
In this unit, second graders are formally introduced to money for the first time. They will learn the value of coins, and solve problems with coins that have money as a real-world context. Students will use strategies such as doubling and grouping to help them approach many kinds of problems.
Unit 2.2
Measuring Length
Unit 2.2
Measuring Length
Second graders will work with standard units of measurement, and understand why standard units are important. For example, if a foot was not an agreed upon length, there would be confusion and disagreement if the same thing was measured by two people with different sized feet. Second graders will make sense of this idea in this unit and use standard measurements to measure the length of many things.
Unit 2.3
Addition within 100
Unit 2.3
Addition within 100
In Kindergarten and Grade 1, students had many experiences with numbers, including addition and subtraction within 20. In this unit, second graders will extend that work with addition into the hundredths place. They will solve word problems using a variety of strategies (number line, place value, decomposition).
Unit 2.4
Measuring Time
Unit 2.4
Measuring Time
Students will work with telling time to the nearest five minutes. Counting by fives is a part of this routine. They will also work on distinguishing notations for morning and afternoon (a.m. and p.m.), as well as other conventions for reading and describing time. There are many real-world connections in this unit.
Unit 2.5
Subtraction within 100
Unit 2.5
Subtraction within 100
Addition and subtraction are related operations. In this unit, second graders take what they have learned about addition and apply it to subtraction, developing a deep understanding of what subtraction is and how and when to use it. They use a variety of strategies they have seen in past units and solve subtraction word problems that use the real world concepts of time, money and length.
Unit 2.6
Problems with Unknowns
Unit 2.6
Problems with Unknowns
Students have spent much of Grade 1 and Grade 2 working with addition and
subtraction. In this unit, second graders consider what operation works best for
different kinds of situations and why.
Is a problem an addition problem?
Is it a subtraction problem?
How are the two related?
Many of the problems in this unit will involve measurement of time or length,
which are two important elements of focus in 2nd grade.
Unit 2.7
Numbers Greater than 100
Unit 2.7
Numbers Greater than 100
Place value understanding means knowing that when we arrange numbers in different places, they have different values. (For example, with the number 234, the 2 stands for 2 hundreds, the 3 stands for 3 tens, and the 4 stands for 4 ones. 234 is the sum of 200 + 30 + 4.)
If we arrange the numbers in a different order, the value changes. In this unit, second graders will continue to work with numbers into the hundreds place. They will use their previous experiences with place value, grouping, and skip counting to make numbers greater than than 100 in many ways.
Unit 2.8
Calculating with
Three-Digit Numbers
Unit 2.8
Calculating with
Three-Digit Numbers
Students have spent much of Grades 1 and 2 working with addition and subtraction. In this unit students build on this work, now working with more complex problems. They add and subtract 3-digit numbers with manipulatives, and they add as many as four 2-digit numbers within the same problem.
Unit 2.9
Working with Figures
Unit 2.9
Working with Figures
Students have been reasoning with shapes since preschool and kindergarten. In this unit, second graders take what they have learned about these shapes, and formalize definitions and ways of putting shapes together and pulling them apart.
Unit 2.10
Two-Step Problems
with Unknowns
Unit 2.10
Two-Step Problems
with Unknowns
Students have spent much of Grades 1 and 2 working with addition and subtraction. In this unit, second graders build on work they did with 1-step problems in Unit 2.6. In this unit, students work with 2-step problems where they often have to add and subtract within the same problem.
Unit 2.11
Data and Graphs
Unit 2.11
Data and Graphs
In this unit, second graders learn that they can organize data in different ways to help them make sense of it. Data are facts or information. Sometimes students will generate the data themselves based on questions they have, and sometimes they will be given data to work with. Students have worked with putting data into categories since kindergarten, and data and graphs will remain a focus in elementary school and through middle and high school into college level math. In this unit, second graders use several different kinds of graphs.
