This resource is designed to help students develop a strong understanding of decimal placement by plotting, estimating, and interpreting decimals on number lines. The activities reinforce number sense and place value concepts, and provide opportunities for reasoning about decimal values.

How to Complete:

1. Section 1: Students will mark given decimals at the correct location on a number line.
2. Section 2: Students will identify which decimal is closest to a given value on a number line.
3. Sections 3 & 4: Students will answer reasoning-based questions about decimal placement and midpoints.
4. Sections 5 & 6: Students will label a horizontal thermometer number line and mark a given temperature. They will then answer a question based on the marked temperature.

Additional Tips:

1. Encourage students to divide number lines into equal segments before plotting decimals.
2. Use hands-on activities, such as placing decimal cards on a large floor number line, to reinforce understanding.
3. Discuss real-life applications of decimals, such as measuring distances or reading scales, to provide context.

Extension Ideas:

1. Estimate and Verify: Have students predict where a decimal should be placed, then check their placement using a number line.
2. Decimal Comparisons: Ask students to compare two decimals and justify which is larger or closer to a benchmark value.
3. Real-World Data: Provide real measurement data, such as race times or ingredient weights, and ask students to represent them on a number line.
