Description
What our Percentages lesson plan includes
Lesson Objectives and Overview: Percentages enables students to define and recognize percent and percentages, and change a percent to a fraction or decimal. At the end of the lesson, students will be able to define and recognize percent and percentages, change a percent to a fraction or decimal. The students will also be able to find the percent of a whole number. This lesson is for students in 4th grade, 5th grade, and 6th grade.
Classroom Procedure
Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the blue box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand.
Options for Lesson
Included with this lesson is an “Options for Lesson” section that lists a number of suggestions for activities to add to the lesson or substitutions for the ones already in the lesson. One optional adjustment to the lesson activity is to allow your students to work in pairs to create word problems for the activity. You can then collect the student-created word problems and use some or all of them for a quiz or for a separate practice page.
Teacher Notes
The teacher notes page includes a paragraph with additional guidelines and things to think about as you begin to plan your lesson. This page also includes lines that you can use to add your own notes as you’re preparing for this lesson.
PERCENTAGES LESSON PLAN CONTENT PAGES
Percentages
The Percentages lesson plan includes two content pages. If you’ve ever taken a test, the teacher likely calculated your grade as a percentage. The higher the number, the better you did on the test. The word percent means out of 100 or per 100. While every test you take doesn’t have 100 questions, your grade can still be calculated as a percentage. Let’s see how!
When looking at percentages, a good place to start is with looking at something that is calculated as out of 100. For example, 100 out of 100 equals 100%, 75 out of 100 equals 75%, 50 out of 100 equals 50%, and so on. You can turn each of these percentages into a fraction. 100/100 = 1, 75/100 = 3/4, and 50/100 = 1/2.
The lesson shows rectangles split into multiple parts with some of the parts shaded. For each rectangle, the lesson lists how much of each rectangle is shaded as both a percentage and a fraction. Just like fractions, percentages are parts of a whole. This means that all percentages can be changed into fractions and vice versa!
Now that you know about percentages and fractions, let’s look at an example. Say you got a score of 90% on a test with 50 questions. How many questions did you get right? To solve, we need to figure out what 90% of 50 is. 90/100 = 9/10 x 50 = 45. Therefore, you got 45 out of 50 questions right. The word “of” means to multiply, so 90% of 50 is the same as the percent times 50. To solve, you change the percent to a fraction, reduce, and then multiply.
It’s very easy to change a percent into a decimal. The decimal point is to the right of the last digit. To change a percent to a decimal, you move the decimal point two places to the left. If the percent is only one digit, you place a zero in front of the decimal. Let’s look at a few examples. To change 25% to a decimal, you move the decimal point two places to the left: 0.25. To change 8% to a decimal, you do the same: 0.08. Finally, to change 145%, you do the same again: 1.45. To change a decimal to a percent, you simply move the decimal point two places to the right!
To summarize, percentages are out of 100, so you can write percentages as fractions or decimals. Fractions and percents are both parts of a whole.
The lesson includes a chart with common percentages, decimals, and fractions. Almost all of the fractions are reduced. You will likely see these percentages, decimals, and fractions very often!
PERCENTAGES LESSON PLAN WORKSHEETS
The Percentages lesson plan includes three worksheets: an activity worksheet and two practice/homework worksheets. You can refer to the guide on the classroom procedure page to determine when to hand out each worksheet.
CREATING PROBLEMS ACTIVITY WORKSHEET
The activity worksheet asks students to create two percent word problems that each include two steps. They will show their work and the steps to solve each problem. They will then have another student solve their problems and solve another students’ problems as well.
FILL IN PRACTICE/HOMEWORK WORKSHEET
For the first practice/homework worksheet, students will fill in the missing percent or decimal, or the missing numerator/denominator, of each fraction shown. They will also solve five percentage proportion problems.
PERCENTAGES PRACTICE/HOMEWORK WORKSHEET
For the second practice/homework worksheet, students will first solve ten percentage proportion problems. They will then solve six word problems.
Worksheet Answer Keys
This lesson plan includes an answer key for one of the practice/homework worksheets. If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.
