Understanding Decimal Place Values

Natalie Rhodes introduces a fifth-grade math lesson on decimal place values, focusing on the relationship between different decimal positions up to the thousandths place. The lesson covers the ten-to-one relationship among decimal places, using the rainbow method to visualize these relationships. Students are guided through exercises using a place value chart to understand how decimals shift when multiplied or divided by powers of ten. The lesson emphasizes understanding decimal place values through practical examples and problem-solving exercises.
