### Goals

• Use addition and subtraction within 100 to solve, explain, and represent one-and two-step word problems with the unknown part in all positions. Second graders will be able to explain their solutions using objects, drawings, and equations with a symbol for the unknown number.

• Demonstrate understanding of place value: the three digits of a three-digit number represent amounts of hundreds, tens and ones.

• Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

• Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.

• Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape

We use Everyday Mathematics (Edition 4), which is a comprehensive Pre-K through grade 6 mathematics program developed by the University of Chicago School Mathematics Project and published by McGraw-Hill Education
