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.

How many more pencils were 15 centimeters than pencils which were 17 centimeters?

There are 5 pencils in the "15 centimeters" row and 3 pencils in the "17 centimeters" row.

To find how many more pencils were 15 centimeters than pencils which were 17 centimeters, subtract.

So, there were 2 more pencils which were 15 centimeters than pencils which were 17 centimeters.

In total, how many pencils were measured?

There are 5 pencils in the "15 centimeters" row, 4 pencils in the "16 centimeters" row, and 3 pencils in the "17 centimeters" row.

To find the total number of pencils which were measured, add.

So, in total, 12 pencils were measured.

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.

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.

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.

So, altogether, there are 9 apples, oranges, and bananas in the bowl.
