What This Standard Means
What Students Need to Do
- Students organize category data in frequency tables or bar graphs. They display numerical measurements, including fractions and decimals, on dot plots or stem and leaf plots. They select a display that matches the data type.
What Mastery Looks Like
- Students choose a display that fits the type of data. Their graphs and tables include correct labels, even numerical scales, and one mark or count for every data value.
Common Misconceptions
- Students may use a bar graph for measurements instead of categories. They may treat 2.5 and 2.50 as different values, space number scales unevenly, or misread place value in a stem and leaf plot.
How to Assess It
- Give students the data 1.2, 1.5, 1.2, 1.8, 1.5, and 1.2. Ask them to make a labeled dot plot with an even scale.

Ways to Teach It
Have pairs measure ten pencils to the nearest tenth of a centimeter, then build a class dot plot with sticky notes.
Ask students to explain in writing why favorite lunch choices need a bar graph while pencil lengths need a dot plot.
Give teams data cards to sort into categories, whole numbers, fractions, and decimals, then match each set to a suitable display.
Survey classroom snack preferences and record a frequency table, then graph the results as a bar graph for a class decision.
