Grade 5 - Place Value - Powers of Ten and Comparing Numbers

In grade five, understanding place value is crucial, extending all the way to the thousandths place. Students should be able to express numbers correctly, like saying "one and twenty-seven hundredths," and visualize them using tools like 100 grids. They also need to grasp that each place value is either a multiplication or division by a power of 10, which is foundational for both comparing numbers and converting units, especially in the metric system.

Additionally, students must compare numbers by analyzing each digit's place value. They should be able to articulate their reasoning, whether by lining up digits, writing numbers in expanded form, or using grouping symbols with multiplication. This thorough understanding of place value not only aids in basic math but also sets the stage for more advanced concepts like measurement and algebra.
