Content Emphasized in Grade 3 Mathematics

Grade 2 Mathematics Newton Public Schools

The goal of the mathematics program in the Newton Public Schools is for all students to understand mathematical concepts and procedures; to be able to apply procedures, concepts, and processes to the solution of challenging problems in a variety of school, home and work settings; and to prepare students for continued study of mathematics and fields that require the use of mathematics.

We continue to use Everyday Mathematics as our core text, having eliminated topics that are no longer content expectations in Grade 2, according to the 2011 Massachusetts Curriculum Framework for Mathematics. Two units of study from Contexts for Learning Mathematics and activities from Developing Number Concepts and Understanding Numbers have been incorporated in order to deepen students’ understanding of number combinations, adding, subtracting, and place value.

Mathematical practices students will use in second grade include:

 making sense of problems and persevering in solving them;

 reasoning abstractly and quantitatively;

 constructing viable arguments and critiquing the reasoning of others;

 modeling with mathematics;

 using appropriate tools strategically;

 attending to precision;

 looking for and making use of structure;

 looking for and expressing regularity in repeated reasoning.

Instructional time in second grade will focus on four critical areas: (1) extending understanding of base-ten notation; (2) building fluency with addition and subtraction; (3) using standard units of measure; and (4) describing and analyzing shapes.

Second grade students develop a broad background by learning concepts and skills in all content strands. The second grade mathematics curriculum emphasizes the following content.

Operations and Algebraic Thinking Represent and solve problems involving addition and subtraction within 100 in a variety of situations; add and subtract fluently within 20 using mental strategies and know from memory all sums of two one-digit numbers; work with equal groups of objects to gain foundations for multiplication.

Number and Operations in Base Ten Understand place value including the value of digits in three digit numbers as well as writing numbers in multiple forms; use this understanding and properties of operations to compare numbers to 1000; fluently add and subtract within 100 using strategies based on place value, properties of operations, or the relationship between addition and subtraction.

Measurement and Data Measure and estimate lengths by using appropriate tools in order to compare lengths and express the difference in standard units; use different standard units of measure and describe how the two measurements are related; use addition and subtraction to solve length-related problems and represent them on a number line diagram; tell and record time from analog and digital clocks to the nearest five minutes; solve word problems involving money and using appropriate symbols.

Geometry Recognize and draw shapes with specified attributes, such as a given number of angles or faces; identify triangles, quadrilaterals, pentagons, hexagons, and cubes; partition rectangles and circles into parts with equal areas, and express the area of each part as a fraction of the whole; describe the whole as two halves, three thirds, four fourths.

Websites

 Everyday Mathematics authors at the University of Chicago have developed an excellent website for parents - Everyday Mathematics Resource and Information Center - everydaymath.uchicago.edu/parents. Information about the research basis for Everyday Mathematics routines is included along with family letters, homework help, a math glossary and a list of grade-appropriate literature with math themes. Note: At this time we do not subscribe to Everyday Mathematics Online.

 The complete text of the 2011 mathematics framework can be downloaded from the Massachusetts Department of Elementary and Secondary Education website: www.doe.mass.edu/frameworks/current.html.

 More information about units of study from Contexts for Learning Mathematics can be found at www.contextsforlearning.com.

 More information about materials from Developing Number Concepts and Understanding Numbers can be found at www.mathperspectives.com.

Home Links Homework often comes as a Home Link. Each Home Link includes a Family Note, which describes the day’s lesson and suggests ways to help your child complete the homework task(s). If you need more information about a specific Home Link, check the “Help with Home Links” section of the Everyday Mathematics website.

The Student Reference Book Students all have access to the Everyday Mathematics My Reference Book for second grade. Topics in the book include directions for all the games played in second grade; simple essays on each strand of mathematics, which provide definitions, examples, a few practice problems, and review of topics from previous years; data tables for use with projects, and a glossary.
