-
Greater than, less than, and equal to
-
Using number lines to justify comparisons
-
-
Operating with decimals
-

-
Applying decimals to money and measurement problems
-
By plotting decimals on number lines, students connect place value to spatial reasoning, which aids later skills like comparing, rounding, and calculating with decimals.
Why Use Number Lines for Decimals?
Number lines help students:
-
See that decimals represent values between whole numbers
-
Understand why 0.45 is greater than 0.4 but less than 0.5
-
Build intuition about decimal size and spacing
-
Move beyond memorization to true number sense
This worksheet provides repeated, scaffolded practice with number lines across various ranges, making abstract ideas feel concrete and meaningful.
How to Use This Worksheet
