# Parts of a Whole

## Activity

As a class, review the value of each circulating coin in relation to a dollar (There are 100 pennies in a dollar, etc.) as well as the decimal representation of the coin value.  Give each student a circle with lines drawn to divide the circle into 100 equal parts.  Separate the students into small groups (2-4 students in each group).  Give each group a plastic cup and 1 of each of the following coins, a cent (penny), nickel, dime, quarter, and a half dollar.  Have the students take turns shaking the plastic cup and pouring one of the coins out.  Depending on the coin that comes out, the students should color in the equivalent number of hundredths (If a penny comes out, the students should color one of the spaces.  If a quarter comes out, the students should color in 25 of the spaces.)  Whoever fills in the circle entirely first (without going over the 100 spaces) is the winner!

## Standards

The project described above reflects some of the national standards of learning as defined by the National Council for the Social Studies (NCSS), the National Council for Teachers of English (NCTE), and the International Society for Technology in Education.  These standards are listed below:

### Mathematics Standards

Number and Operations:  Students will understand that fractions are a part of a whole.

Connections:  Through this activity students will recognize that coins are worth a fraction of a dollar.  They should also be introduced to the idea that a fraction has an equivalent decimal representation.

Representation:  Students will represent the value of different coins by shading in their equivalent fractional parts in the circle.
