Grade 5 - Place Value - Visualizing Place Value with Decimals and Rounding

In grade five, students must understand and express decimals correctly, recognizing the significance of each digit's place value. For example, a number like 1.27 should be read as "one and twenty-seven hundredths," with tools like 100 grids and number lines helping to visualize and connect decimals to fractions.

Rounding decimals is also crucial. Using a number line allows students to see where a decimal falls and whether it should round up or down. Simple strategies, such as underlining key digits, help clarify the process, making decimals more manageable and building a solid math foundation.
