When Are We Ever Going to Use This?
DescriptionThis lesson is intended as a wrap-up following the teaching of relationships among fractions, decimals, and percents. It could be used following any lesson as a means to encourage the understanding of real-world applications of mathematics.
ObjectivesThe student knows the relationships among fractions, decimals, and percents given a real-world context.
Materials-Daily newspapers, magazines, any type of media which uses fractions, decimals, ratios, and percents
-Glue or glue sticks
PreparationsGather necessary materials- poster board, glue, markers.
Have on hand extra newspapers and magazines for students who did not bring in examples prior to lesson.
ProceduresNOTE: Students have already learned how to compute percents, decimals and fractions.
The students gain a better understanding of the importance of knowing how to use percents, ratios, fractions, and decimals in everyday life.
1. A few days prior to the lesson, ask students to bring in examples of percents, ratios, fractions, and decimals that they find in newspapers and magazines, etc. Show students examples that you have found in the daily paper
2. On the day of the lesson, assign students to groups of four or five.
3. Instruct students to work in groups to develop posters that depict the use of the percents in the media which they brought in.
4. Encourage students to be creative emphasizing the many ways percents are used in articles and advertisements.
5. Provide real life examples of how percents are used in the media and how understanding what a percent means will enable them to make better decisions in the real world.
1. Ask students to present their posters to the class.
2. Encourage students to discuss the many examples that they have used in their posters.
3. While groups are presenting, lead the discussion to the relationship among fractions, decimals, and percents in the real-world using the examples on the posters.
4. Instuct students to change the percents to the decimal and fractional equivalents.
5. Have the students turn in the conversions along with a short paragraph explaining whether or not the use of percents is the best method to use to explain the examples presented.
AssessmentsThe students will demonstrate understanding by completing the assigned posters and the conversions of percents to decimals and fractions. Offer feedback to those who are having difficulty. Assess students on their ability to state the relationship among percent, decimals and fractions and to state whether percent is the most appropriate method in the real world context shown on the poster. Do not count off for incorrect calculations. Pair more able students with those who are having difficulty doing the calculations correctly.
