1 Crayon

Crayons have been around since 1903 and are a popular drawing and coloring tool. A crayon is made out of colored wax and is used to color images in coloring books, write on paper, and other forms of artwork. 

Crayons are commonly found in schools where kids use them quite often. They can be purchased in most office supply and larger chain stores. 

A single crayon is normally 3 inches long and is a perfect example of something that can be used to reference the size of 3 inches.

1/3 Lunch plate diameter

Lunch plates can vary in size but on average, a lunch plate is 9 inches in diameter. This is the distance from one side of the plate to the other cutting the plate into 2 equal halves. 

Lunch plates are normally smaller than dinner plates and larger than dessert plates. 

If you picture the diameter of a lunch plate, 3 inches is exactly one-third of the size.
