Picture graphs and bar graphs
Build and interpret picture and bar graphs
Problem types
- Build a frequency table
- Total from a bar chart
- Compare chart categories
Builds on
- Reading a categorical graph
- Comparing two groups by matching · Useful idea
Comparing two bars is comparing two groups: the taller bar stands for the group with more.
- Subtracting within 10 · Useful idea
The difference between two bars is the subtraction of their counts.
- Numerals through 20 · Useful idea
The count in each category is written as a numeral, and that numeral names how tall its bar is.
Leads to
- Reading scaled picture and bar graphs
- Frequency tables and scaled bar graphs
- Dot plots, histograms, and box plots · Extend the idea
A bar graph of categories becomes a histogram when the bars show how many values fall in each interval.
- Percent of a number · Extend the idea
The share of each bar in the total is a percent, and a circle graph shows those percents as parts of a whole.
