What Is Benchmark MA.2.DP.1.1?

Students collect data, sort it into categories, and show it with tally marks, tables, pictographs, or bar graphs. Every display needs a title, labels, and units.

Graphs can go up and down or side to side. In Grade 2, scales count by ones, fives, or tens, and each picture in a pictograph stands for 1, 5, or 10.

Official benchmarkCollect, categorize and represent data using tally marks, tables, pictographs or bar graphs. Use appropriate titles, labels and units.

How it is tested: Grade 2 students take FAST Star Math, Florida's math test for Kindergarten through Grade 2.

Worked Examples

Worked Example 1

Tally Marks

Nine students chose grapes as their favorite fruit. How do you show 9 with tally marks?
  1. 1Tally marks are drawn in groups of 5: four lines with a fifth line across them.
  2. 29 is one group of 5 and 4 more lines.
Answer: One bundle of 5 tally marks and 4 more marks

Worked Example 2

Choosing a Scale

A bar graph will show 15, 30, 25, and 40. Should the scale count by ones, fives, or tens?
  1. 1Counting by ones would need 40 marks, which is too many.
  2. 2With tens, 15 and 25 would fall between the lines.
  3. 3All the numbers are on the count by fives: 5, 10, 15, 20, 25, ...
Answer: Count by fives

Common Mistakes to Watch For

Leaving off the title and labels

Wrong:A bar graph with bars but no title, no category names, and no numbers on the scale.

Add a title, label each bar, and number the scale so anyone can read the graph.

Using an uneven scale

Wrong:A scale marked 0, 5, 10, 20, 30

Count by the same amount every time: 0, 5, 10, 15, 20, 25, 30.

Helpful Math Tip

Collect real family data, like favorite snacks or the weather each day for two weeks, and make a tally chart and then a bar graph together.
