What you'll learn

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
