1.  The s
tudents will write fractions that represent a model.
2.  The students will relate size of fractions to a picture.
3.  The students will create graphic representations of fractions.


1.  Open the Internet and have students type in the following web address:

2.  Click in the rectangle that aligns Number and Operations under grades 3-5.

3.  Scroll down to the following activity and click on it:

Fractions - Naming Write the fraction corresponding to the highlighted portion of a shape.

4.  Count the number of colored parts in the picture. Enter that number as the numerator in the fraction. The numerator is the first (or top) number in a fraction. It describes the fractional part of a whole unit.

5.   Count the total number of parts in the picture. Enter that number as the denominator in the fraction. The denominator is the second (or bottom) number in a fraction. It describes the total number of parts that make up a whole unit.

6.  Ask:  Can you devise a method to remember that the numerator describes the number of parts, and the denominator describes the number of parts that makes up the whole unit?

7.  Click on the "Check" button to see if you described the picture accurately. Click on the "New Fraction" button to try a new fraction.

8.  Follow the computer activity. When completed, close out and go back to desktop. Have students go back to the classroom and create 5 graphic representations of fractions on a sheet of paper, much like what they were seeing in the computer lab.

9.  Students should exchange papers with a neighbor.  Each person should write the mathematical fraction for each graphic representation and hand it in for a grade.

Lesson Details:

  1. Identify how many parts of the whole unit are highlighted and enter that number as the numerator in the fraction.
  2. Identify how many parts make up the whole unit and enter that number as the denominator in the fraction.
  3. Check whether the fractional representation corresponds to the picture representation by clicking on the "Check" button.
  4. To begin relating the size of a fraction to a picture representation, consider asking pupils to estimate the fraction before they count the various parts.

Can students accurately link picture representations with fractions?
Activity can be awarded the following points:

10 points Listening and following directions
        20 points Actively engaged in the activity
        20 points Writing fractions based on graphic representations.
        Add everything together and multiply by 2 to obtain a grade.

Based on your class needs you may need to spend more or less time working in the lab.  You could also modify the number of graphical representations each student creates in the classroom.

There are several other fraction activities on the main web-site that students can explore as the learn more about fractions.
