Description
Do you have only a fraction of time to teach fractions? Well, here is the lesson for you! Fantastic Fractions teaches students the difference between 1/2, 1/3, and 1/4. Students will use their imagination and pictures from magazines.
Objectives
The student uses concrete materials to represent fractional parts of a whole (one half, one fourth).
Materials
-Examples of the fractions 1/2, 1/3, and 1/4 from magazines
-Magazines (at least three per group of three students)
-Scissors (one per child)
-Glue (one per group of three students)
-Bulletin board paper (two feet for each group)
-Provided Fantastic Fractions worksheet page 1 (see attached file)
-Markers
Preparations
1. Collect enough magazines so that each group of three children will have three magazines.
2. Prepare the examples of fractions from magazines of 1/2, 1/3, and 1/4. See page two of the file attachment for examples.
3. Label the bulletin board paper at the top with 1/2, 1/3, and 1/4 for each group.
4. Run enough of the Fantastic Fractions worksheet so that each child has a copy.
5. Make enough patterns of fractions, or have the geo shapes handy so that each group has one of each fraction.
Procedures
1. Teacher will model fractions with an introductory fractions lesson. This will set up the activity that the students will be doing. See page two of the attached sheet for examples of fractions using pictures.
2. Show the students pictures of objects that are missing parts. For example, a picture of pizza that you only can see 1/4 of it or a dog that has 1/2 of the dog showing. Have 3 (1/2, 1/3, 1/4) examples of pictures cut out of magazines to show these concepts. Hint: Make sure that you have the missing parts outlined so that they can see the original shape of the object.
2. Give each student a copy of the fractions patterns that you have made to help them with the shapes. You may also have them use geometric blocks to trace over the shapes.
3. Put the students in groups of three.
4. Hand out magazines to each of the groups.
5. Pass out a large sheet of bulletin board paper (any color) about two feet long that has been divided into three sections and labeled (1/2, 1/3, and 1/4) to each group.
6. Tell the students that they are to work with their team to find pictures in the magazines that they can cut out and show examples of 1/2, 1/3, and 1/4.
7. Each group should paste their examples on their bulletin board paper. Make sure that they are putting their examples in the correct location.
8. Students can either cover up the picture with construction paper, or they can black it out with a marker.
9. After each group has finished, have them share their examples with the rest of the class.
10. Let the students try to guess what picture the students are only showing a fraction of.
11. Pass out one copy of the provided worksheet entitled "Fantastic Fractions" as an assessment to see if the students have mastered (80% mastery) fractions.
Assessments
The assessment for this lesson will include the following things:
1. Teacher observation- When the students are working in groups, make sure that they are able to place the fraction pictures in the correct section. Students should have at least two pictures for each fraction on their group's paper.
2. The attached file entitled "Fantastic Fractions" will be used to assess the students' understanding of fractions. Students need to have 80% mastery or more on this sheet.
