Ready to print
Start with a ready-made worksheet
Read from left to right as values increase. Use the evenly spaced ticks to locate or compare numbers.
Download the practice pages alone, or include a separate answer key or teacher model. Longer activities may use more than one page.
Customize this worksheetBefore you customize
Enter signed decimal endpoints with at most three decimal places and absolute values no greater than 1,000. The end must exceed the start, the chosen increment must divide the span exactly, and the line must have 2–201 ticks. Unreadable labels are rejected: choose fewer labels, a larger increment or a shorter span. Requested labels are never silently removed.
Learning objective
What this activity builds
Connect a number with its position and compare equal intervals on a horizontal scale.
Worked example
A line starts at 0 and each step is 1/2. What is the third tick after 0?
1 1/2
Three equal half-unit intervals make 3/2, or 1 1/2. Count the spaces after zero, rather than counting zero as the first jump.
Teaching notes
Make the practice count
- For a first lesson, customize the line to start at 0 and end at 10 with a step of 1 and all labels. The ready-made reference uses -5 to 5.
- Use all labels to introduce a scale, then keep only endpoints or selected labels for teacher-led practice. Labels are shown only at ticks that exist on the chosen grid.
- These ten axes are reusable reference paper with no assessment points. The optional teaching model repeats the reference; a new seed does not change the chosen axes.
