## End of Year Goals

### 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

## Learning Resources

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

### Family Letters

Stay up-to-date on what your child is learning in class. Family Letters contain background information, vocabulary, games and more for each section (unit).
