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.
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
