Technology Applications  §126.3.4 (A,B)
Objective:
1. The students 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.
Procedures:
1. Open the Internet and have students type in the following web address: http://matti.usu.edu/nlvm/nav/vlibrary.html
2. Click in the rectangle that aligns Number and Operations under grades 35.
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:
Assessment:
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.
Modifications:
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.
Extensions:
There are several other fraction activities on the main website that
students can explore as the learn more about fractions.
