Virginia SOL 3.PS.1.d
The Standard
Organize and represent a data set using bar graphs with a title and labeled axes, with and without the use of technology tools. Determine and use an appropriate scale (increments limited to multiples of 1, 2, 5 or 10).
Virginia Standards of Learning for Mathematics · The student will apply the data cycle (formulate questions; collect or acquire data; organize and represent data; and analyze data and communicate results) with a focus on pictographs and bar graphs.

What This Standard Means
What Students Need to Do
- Students organize a data set in a bar graph by adding a title, category labels, and labeled axes. They select increments of 1, 2, 5, or 10 and create graphs by hand and with a technology tool.
What Mastery Looks Like
- Students choose a scale that fits the data and mark equal intervals on the number axis. Their bars have correct heights, equal widths, and clear category labels, axis labels, and a title.
Common Misconceptions
- Students may count each grid line as one even when the scale increases by 2, 5, or 10. They may use uneven intervals, omit zero, switch the axes, or forget the title and axis labels.
How to Assess It
- Exit ticket: Graph these votes: soccer 14, tag 8, chalk 6, swings 10. Choose a scale from 1, 2, 5, or 10, then include a title and labeled axes.

Ways to Teach It
Give pairs grid paper and linking cubes to graph class pet votes, then rebuild the graph using a scale of two.
Show two graphs of the same data and ask, "Which scale makes the data easiest to read, and why?"
Play Scale Match by having students pair data cards with graph templates marked in increments of 1, 2, 5, or 10.
Survey daily lunch choices, enter the totals in a spreadsheet, and compare the digital bar graph with a hand-drawn version.
