Maryland Math 4.DS.A.1

4.DS.A.1 is a cluster heading. These are the individual standards under it.

• 4.DS.A.1.a

  Create scaled data visualization (e.g. bar graphs for categorical data; line plots with fraction units of halves, fourths, and eighths for numerical data) to di...

• 4.DS.A.1.b

  Summarize data presented in scaled data visualizations (e.g. bar graphs, line plots) and draw conclusions about the data.

• 4.DS.A.1.c

  Compare and contrast different data visualizations of the same data by varying attributes (e.g., reordering bars, changing the scale) and explain how changing t...

01

What Students Need to Do

Students ask a question, collect answers or measurements, and organize the results. They make scaled bar graphs for categories and line plots for measurements in halves, fourths, or eighths. They use the graph and its context to answer questions and explain what the data shows.

02

What Mastery Looks Like

A student chooses a graph that fits the data and labels its scale and units. They can identify the most common result and compare counts. They can explain that changing a bar graph's scale or bar order does not change the data, but can change what catches the eye.

03

Common Misconceptions

Students may count each grid mark as one vote when the scale counts by fives. They may space 1/2, 3/4, and 7/8 evenly on a line plot. Some think a change in bar order or scale means the counts changed.

How to Assess It

Exit ticket: Paper strips measure 1/2, 1/2, 3/4, 7/8, 7/8, 7/8, and 1 inch. Make a line plot marked in eighths, then name the most common length.

1. 01

   Measure seven paper strips to the nearest eighth inch, record their lengths, and build a line plot with eighth-inch tick marks.

2. 02

   Show two bar graphs of the same lunch votes with scales of one and five; ask which looks more dramatic and why.

3. 03

   Play graph switch: give pairs fruit-vote tally cards and have them draw bar graphs with different bar orders, then compare claims.

4. 04

   Survey how classmates travel to school, make a scaled bar graph, and write one claim about the most common way.
