NH. State Grade 2 Common Core Mathematics Expectations

New Hampshire Curriculum Framework Mathematics June 6 2006

• GOALS FOR MATHEMATICS EDUCATION

• We commit to six primary goals. These goals are closely aligned with those espoused by various national commissions and groups in their efforts to reshape the teaching and learning of mathematics.

• All students will develop a firm grounding in number sense that includes computational fluency.

• All students will develop a basic understanding of key concepts and principles central to the study of geometry, algebra, probability, and data

analysis, while appreciating the interrelationships of all areas of mathematics.

• All students will develop strong mathematical problem solving and reasoning abilities. • All students will develop positive attitudes about

mathematics.

• All students will develop the ability to use appropriate technology to solve mathematical problems.

• All students will develop the ability to communicate their understanding of mathematics effectively.

Expectations for Grade 2 Mathematics

• M:N&O:2:1 Demonstrates conceptual understanding of rational numbers with respect to: whole numbers from 0 to 199 using place value, by applying the concepts of equivalency in composing or decomposing numbers (e.g., 34 = 17 + 17; 34 = 29 + 5); and in expanded notation (e.g., 141 = 1 hundred + 4 tens + 1 one or 141 = 100 + 40 + 1) using models, explanations, or other representations; and positive fractional numbers (benchmark fractions: a/2, a/3, or a/4, where a is a whole number greater than 0 and less than or equal to the denominator) as a part to whole relationship in area and set models where the denominator is equal to the number of parts in the whole using models, explanations, or other representations.

(2006 NH Curriculum Frame Work, p10 of 69)

• M:N&O:2:5 Demonstrates understanding of monetary value by adding coins together to a value no greater than $1.99 and representing the result in dollar notation; making change from $1.00 or less, or recognizing equivalent coin representations of the same value (values up to $1.99).

(2006 NH Curriculum Frame Work, p11 of 69)

• M:N&O:2:7 Makes estimates of the number of objects in a set (up to 50) by selecting an appropriate method of estimation. (IMPORTANT: The intent of this GLE is to embed estimation throughout the instructional program, not to teach it as a separate unit.)

(2006 NH Curriculum Frame Work, p12 of 69)

• M:G&M:2:7 Measures and uses units of measures appropriately and consistently, and makes conversions within systems when solving problems across the content strands. (2006 NH Curriculum Frame Work, p20 of 69)

Place Value:

• M:N&O:2:1 Demonstrates conceptual understanding of rational numbers with respect to: whole numbers from 0 to 199 using place value, by applying the concepts of equivalency in composing or decomposing numbers (e.g., 34 = 17 + 17; 34 = 29 + 5); and in expanded notation (e.g., 141 = 1 hundred + 4 tens + 1 one or 141 = 100 + 40 + 1) using models, explanations, or other representations; and positive fractional numbers (benchmark fractions: a/2, a/3, or a/4, where a is a whole number greater than 0 and less than or equal to the denominator) as a part to whole relationship in area and set models where the denominator is equal to the number of parts in the whole using models, explanations, or other representations.(2006 NH Curriculum Frame Work, p10 of 69)
