Texas Essential Knowledge and Skills (TEKS): 3.13.a
collect, organize, record, and display data in pictographs and bar graphs where each picture or cell might represent more than one piece of data;
Texas Essential Knowledge and Skills (TEKS): 3.13.b
interpret information from pictographs and bar graphs; and

In a picture graph, the number of pictures represents
the number of items in each category.

Example:

The table shows that Larissa drank 2 fluid ounces of water at the first water stop.
Since

equals 2 fluid ounces, there is one

in the first water stop row.

2 fluid ounces

The table shows that Larissa drank 6 fluid ounces of water at the second water stop.
Since

equals 2 fluid ounces, there are three

in the second water stop row.

2 fluid ounces

The table shows that Larissa drank 4 fluid ounces of water at the third water stop.
Since

equals 2 fluid ounces, there are two

in the third water stop row.

2 fluid ounces

In a picture graph, the number of pictures represents
the number of items in each category.

Example:

In the graph, there are five shirts next to "Darius."
Each

represents 2 shirts.
So, Darius took 10 (5 × 2) shirts to the dry cleaners.

There are three shirts next to "Larry."
So, Larry took 6 (3 × 2) shirts to the dry cleaners.

Subtract 6 from 10 to find how many more shirts Darius took to the dry cleaners than Larry.

10 - 6 = 4

So, Darius took 4 more shirts to the dry cleaners than Larry.

In a bar graph, the heights of the bars represent
the number of items in each category.

Example:

The table shows that the grocery store has 15 boxes of raisin bran in stock.
So, the bar above "Raisin Bran" in the graph ends at 15.

The table shows that the grocery store has 11 boxes of corn flakes in stock.
So, the bar above "Corn Flakes" in the graph ends at 11.

The table shows that the grocery store has 17 boxes of granola in stock.
So, the bar above "Granola" in the graph ends at 17.

In a bar graph, the heights of the bars represent
the number of items in each category.

Example:

The bar over "Granola" ends at 18, and the bar over "Corn Flakes" ends at 11.
So, there are 18 boxes of granola and 11 boxes of corn flakes in stock.

Subtract the number of boxes of corn flakes from the number of boxes of granola.

18 - 11 = 7

So, there are 7 more boxes of granola than corn flakes in stock.
