How to Use Models to Place Decimal Numbers in Order
Using models to place decimal numbers in order helps students visualize and compare the relative values of decimals. Base-10 models such as base-10 blocks, place value charts, or grids can be particularly helpful in this process.

Step 2: Identify the decimal numbers:
Write down the decimal numbers you want to place in order.
Step 3: Fill in the place value chart:
Create a place value chart with columns for each decimal place needed (ones, tenths, hundredths, etc.). Write each decimal number in the chart, aligning the digits with their respective place value columns.
Step 4; Compare the digits:
Starting with the leftmost column (usually the ones in place), compare the digits in each row. If the digits are the same, move to the next column to the right (e.g., from tenths to hundredths) and continue comparing.
Step 5: Order the decimal numbers:
Based on your comparison of the digits, arrange the decimal numbers in ascending or descending order.
