Lesson Plan

Add and subtract decimals to hundredths by aligning place values and regrouping as needed, using strategies grounded in place value understanding

Multiply decimals to hundredths using area models or place value reasoning to determine both the product and the correct placement of the decimal point

Divide decimals to hundredths by reasoning about how many groups fit or by converting to whole-number equivalents, then interpreting the quotient

Use estimation to judge the reasonableness of a decimal computation before and after calculating

Represent decimal operations with concrete models (base-ten blocks, grids, area models) or drawings and connect those representations to a written method

Explain the reasoning behind each step of a decimal computation using place value language

5.NBT.B.7

5.NBT.B.7: Add, subtract, multiply, and divide decimals to hundredths, 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 and explain the reasoning used.
