Create a picture graph and bar graph to represent data with up to four categories.
Using information presented in a bar graph, solve simple “put-together,” “take-apart,” and “compare” problems.
Using Venn diagrams, pictographs, and "yes-no" charts, analyze data to predict an outcome.

2nd Grade Math - Data Displays & Analysis Lesson
A line plot is a data display, along a number line, which shows frequency.
The frequency is represented with a marker, like an x or a dot.
Example:
To make a line plot for the data, make a number line with the lengths of the pencils along the bottom.
Then, place the same number of x's above each length as the number shown with each length in the table.
So, place 5 x's above 15 centimeters, place 4 x's above 16 centimeters, and place 3 x's above 17 centimeters.
Pencils
Length [centimeters]
A picture graph is a data display which shows frequency.
The frequency is represented with a picture or symbol.
Example:
To make a picture graph for the data, use a picture to represent 1 lunch brought from home.
Then, make a table and place the same number of pictures next to each name as is given in the table.
So, place 3 pictures next to Shane, place 4 pictures next to Shannon, and place 2 pictures next to Sheila.
Note that in some picture graphs the picture represents more than 1. A scale is used to show the value of each picture.
Brought Lunch
Shane
Shannon
Sheila
= 1 lunch
A bar graph is a data display which shows frequency.
The frequency is represented with a shaded bar along a numbered axis.
Example:
To make a bar graph for the data, use a horizontal line and a vertical line. Place the fruit names along one line and place numbers along the other.
Then, for each fruit, make a shaded bar which ends at the same number as is given with each fruit in the table.
So, the bar for "Apples" ends at 4, the bar for "Oranges" ends at 3, and the bar for "Bananas" ends at 2.
A bar graph is a data display which shows frequency.
The frequency is represented with a shaded bar along a numbered axis.
Example:
How many more apples than bananas are in the bowl?
The bar above "Apples" ends at 4, and the bar above "Bananas" ends at 2.
To find how many more apples than bananas are in the bowl, subtract the number of bananas from the number of apples.
4 - 2 = 2
So, there are 2 more apples than bananas in the bowl.
How many apples, oranges, and bananas are in the bowl altogether?
The bar above "Apples" ends at 4, the bar above "Oranges" ends at 3, and the bar above "Bananas" ends at 2.
To find how many apples, oranges, and bananas are in the bowl altogether, add the numbers of each fruit.
4 + 3 + 2 = 9
So, altogether, there are 9 apples, oranges, and bananas in the bowl.
