Title
Fun with Fractions
Lesson Objective
Activities lead the students to the understanding that the larger the denominator the more parts the whole is being divided into.
Background Information for Teacher
Words in bold are said by the teacher.
Student Prior Knowledge
A fundamental knowledge of number sense and relationship (greater than, less than, equal to, grouping) needs to be in place as well
as the ability to add, subtract, multiply, and divide small numbers. In addition, students should understand what the numerator and
denominator of a fraction represents and that halves, thirds, fourths, sixths, and eighths are represented with the symbols 1/2, 1/3,
1/4, 1/6, and 1/8.
Materials:

Step-by-Step Guided Lesson
Step 1: Start Video
(Tips: Interact with the video by pausing, to ask questions or discuss information viewed with student.)
Step 2: Teach Lesson
Take the student outside and tell them we are going to explore dividing something outside into parts.
Find objects outside that has pieces (i.e. rocks, leaves, etc.). Collect an even number of objects.
Begin by asking the student how many ( )are in the whole group?
Now ask the students to divide the objects into halves.
Make sure the student moves the object far enough apart that the division is clear.
Use your whiteboard and marker to have the student help you figure out how many the fraction is equal to after you have divided
them (i.e., 1/3 of 24 is 6).
Continue to do this using student objects numbers, having them continue to divide into halves, thirds, fourths, sixths, and eighths.
Activity
Explain to the student that they are now going to make some fraction strips that show how we can divide the whole into equal parts
and compare them.
Give the student six different colored strips of color gel paper (1-inch x 12 inches). Take one colored strip and label it whole (make
sure the student is using the same color—it will help as you continue to work with the strips.
Take a second strip and have the student divide the strip in half. Have them label each part with 1/2.
Continue doing this with each different colored strip until the student has divided and labeled whole, 1/2, 1/3, 1/4, 1/6, and 1/8. This
