5.5 Patrones entre valores posicionales y operaciones con decimales
Unit Goals
- Students build from place value understanding in grade 4 to recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and $\frac{1}{10}$ of what it represents in the place to its left. They use this place value understanding to round, compare, order, add, subtract, multiply, and divide decimals.
Section A Goals
- Compare, round and order decimals through the thousandths place based on the value of the digits in each place.
- Read, write, and represent decimals to the thousandths place, including in expanded form.
Section B Goals
- Add and subtract decimals to the hundredths using strategies based on place value.
Section C Goals
- Multiply decimals with products resulting in the hundredths using place value reasoning and properties of operations.
Section D Goals
- Divide decimals with quotients resulting in the hundredths using place value reasoning and properties of operations.
