Mathematics, Grade 2 Student Learning Profile 
Within a wellbalanced mathematics curriculum, the primary focal points at Second Grade are making comparisons within the base10 place value system, solving problems with addition and subtraction within 1,000, and building foundations for multiplication. The student will:  Apply mathematics to problems arising in everyday life, society, and the workplace.
 Use a problemsolving model that incorporates formulating a plan or strategy, justifying the solution, and evaluating the problemsolving process and the reasonableness of the solution.
 Select tools, including real objects, manipulatives, paper and pencil as appropriate, and techniques, including mental math, estimation, and number sense as appropriate, to solve problems.
 Communicate mathematical ideas and reasoning using multiple representations, including symbols, diagrams, graphs, and language as appropriate.
 Analyze mathematical relationships to connect and communicate mathematical ideas.
 Display, explain, and justify mathematical ideas and arguments using precise mathematical language in written or oral communication.
 Use concrete and pictorial models to compose and decompose numbers up to 1,200 in more than one way as a sum of so many thousands, hundreds, tens, and ones.
 Use standard, word, and expanded forms to represent numbers up to 1,200.
 Generate a number that is greater than or less than a given whole number up to 1,200.
 Use place value to compare and order whole numbers up to 1,200 using comparative language, numbers, and symbols (>, <, or =).
 Locate the position of a given whole number on an open number line.
 Name the whole number that corresponds to a specific point on a number line.
 Partition objects into equal parts and name the parts, including halves, fourths, and eighths, using words.
 Explain that the more fractional parts used to make a whole, the smaller the part; and the fewer the fractional parts, the larger the part.
 Use concrete models to count fractional parts beyond one whole using words and recognize how many parts it takes to equal one whole.
 Identify examples and nonexamples of halves, fourths, and eighths.
 Recall basic facts to add and subtract within 20 with automaticity.
 Add up to four twodigit numbers and subtract twodigit numbers using mental strategies and algorithms based on knowledge of place value and properties of operations.
 Solve onestep and multistep word problems involving addition and subtraction within 1,000 using a variety of strategies based on place value, including algorithms.
 Generate and solve problem situations for a given mathematical number sentence involving addition and subtraction of whole numbers within 1,000.
 Determine the value of a collection of coins up to one dollar.
 Use the cent symbol, dollar sign, and the decimal point to name the value of a collection of coins.
 Model, create, and describe contextual multiplication situations in which equivalent sets of concrete objects are joined.
 Model, create, and describe contextual division situations in which a set of concrete objects is separated into equivalent sets.
 Determine whether a number up to 40 is even or odd using pairings of objects to represent the number.
 Use an understanding of place value to determine the number that is 10 or 100 more or less than a given number up to 1,200.
 Represent and solve addition and subtraction word problems where unknowns may be any one of the terms in the problem.
 Create twodimensional shapes based on given attributes, including number of sides and vertices.
 Classify and sort threedimensional solids, including spheres, cones, cylinders, rectangular prisms (including cubes as special rectangular prisms), and triangular prisms, based on attributes using formal geometric language.
 Classify and sort polygons with 12 or fewer sides according to attributes, including identifying the number of sides and number of vertices.
 Compose twodimensional shapes and threedimensional solids with given properties or attributes.
 Decompose twodimensional shapes such as cutting out a square from a rectangle, dividing a shape in half, or partitioning a rectangle into identical triangles and identify the resulting geometric parts.
 Find the length of objects using concrete models for standard units of length.
 Describe the inverse relationship between the size of the unit and the number of units needed to equal the length of an object.
 Represent whole numbers as distances from any given location on a number line.
 Determine the length of an object to the nearest marked unit using rulers, yardsticks, meter sticks, or measuring tapes.
 Determine a solution to a problem involving length, including estimating lengths.
 Use concrete models of square units to find the area of a rectangle by covering it with no gaps or overlaps, counting to find the total number of square units, and describing the measurement using a number and the unit.
 Read and write time to the nearest oneminute increment using analog and digital clocks and distinguish between a.m. and p.m.
 Explain that the length of a bar in a bar graph or the number of pictures in a pictograph represents the number of data points for a given category.
 Organize a collection of data with up to four categories using pictographs and bar graphs with intervals of one or more.
 Write and solve onestep word problems involving addition or subtraction using data represented within pictographs and bar graphs with intervals of one.
