Read the chart
Read points, find the highest and lowest values, calculate a range and describe first-to-last change. Six questions establish careful scale reading.
Line graph worksheets
with answers.
Practice reading a line graph, finding changes and plotting a sequence of observations. Download original PDF practice sheets or replace the values, then print the questions and a separate answer key.

- What value is shown for Tue?
- Which label or labels have the highest value?
- Which label or labels have the lowest value?
- What is the difference between the highest and lowest values?
- How does the value change from Mon to Sat?

What this worksheet teaches
A line graph plots values in a specified order and connects consecutive points. Read the point values against the vertical scale, then compare adjacent points to identify increases, decreases and unchanged intervals.
Choose a sheet, make it yours, print
- Choose reading, comparison or drawing practice. Reading and comparison have six questions; drawing has three tasks and a labelled blank chart.
- Keep the sample, generate a fresh set, or replace the data. Upload CSV or Excel, or paste spreadsheet cells. Select and check the columns before applying. The questions and worked answers are recalculated from the selected values.
- Preview and download. Print A4 or US Letter at 100%. The PDF has one question page followed by an optional answer-key page. Viewing the key does not add answers to the question page.
Use 3–8 distinct labels, each up to 18 characters, and one whole-number value from 0 to 100 per label. Labels are equally spaced in the supplied order. Use equally spaced observations for time-based practice; irregular time intervals belong in the general line-graph maker.
Three ready-to-print practice packs
Original fictional examples. Each PDF contains one question page and one answer-key page. Download without signing in or enabling JavaScript.
Compare and explain
Compare changes, list increasing and decreasing intervals, and explain why connecting lines do not establish intermediate measurements. Six questions with worked answers.
Draw the chart
Plot values from a table and connect consecutive points in order, then identify the highest value and range. Three tasks with a matching completed graph.
A worked example with the original values
Seedlings counted each day · Seedlings. Mon: 12; Tue: 18; Wed: 16; Thu: 16; Fri: 10; Sat: 2. These are fictional practice values, not findings or benchmarks.
- What value is shown for Mon?
- 12 Read Mon against the vertical scale.
- What value is shown for Tue?
- 18 Read Tue against the same scale.
- Which label or labels have the highest value?
- Tue The maximum is 18. Include all ties.
Methods and limits
Points remain in the supplied label order, with equal horizontal spacing and a vertical baseline of zero. No smoothing, resampling or implicit aggregation occurs.
First-to-last change is last value minus first value. Positive change is an increase; negative change is a decrease. Adjacent equal values are neither increasing nor decreasing.
A connecting segment is a visual connection between observations. It does not prove unrecorded intermediate values, and the overall change can hide increases and decreases within the sequence.
The graph and worksheet use native Apache ECharts axes and marks. Question and answer exports share the same values and scale. PDF pages contain high-resolution images; use the accessible text view or CSV downloads for selectable values and answers. There is no automated grading or curriculum-certification claim.
Common mistakes to check
- A steep-looking line depends on the axis scales and the graphic’s proportions. Read the numbers before making comparisons.
- A sequence can end where it began while changing substantially in between. Check each interval.
- Use time intervals of equal duration when labels are equally spaced. Do not infer a daily rate from unequal intervals.
Questions about using these sheets
Can I print only the questions?
Yes. Uncheck “Include a separate answer-key page” before downloading a customized PDF. For ready-made packs, print only page 1. The worksheet SVG also contains questions only.
Can I use my class data?
Yes, within the limits above. Choose “Upload a file” or “Paste data”, select the relevant columns, and review before replacing the current values. The imported data and generated files stay in your browser. Replacing a sample removes its fictional-data label.
Are the answers recalculated when data changes?
Yes. Question values, ties, comparisons and worked answers are derived from the current chart data. Changing paper size preserves the dataset. “Generate fresh data” intentionally replaces it with a new fictional practice set.
Can I share the worksheets?
Yes. Print and share these original worksheets for classroom or home practice, without an account or a watermark across the work. ChartsAI is a free, open-source project by SupaMakers.
