Description
What our Compare Percentages lesson plan includes
Lesson Objectives and Overview: Compare Percentages teaches students strategies for comparing two percent proportion problems correctly. At the end of the lesson, students will be able to compare the amounts of parts between two percent proportion problems. This lesson is for students in 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 addition to this lesson is to have your students use real world examples from sales or products to compare percentages. You can also teach students to find equivalent fractions to find a part. Finally, you can have your students create advertisements for their favorite items with prices that are percent proportions.
Teacher Notes
The teacher notes page includes lines that you can use to add your own notes as you’re preparing for this lesson.
COMPARE PERCENTAGES LESSON PLAN CONTENT PAGES
Compare Percentages
The Compare Percentages lesson plan includes two content pages. Before learning to compare percentages, it’s important to review how to calculate numbers from percentages. A percent is the ratio of a number to one hundred. We write them using the % sign. To compare percentages, we need to know what part of the whole we are comparing. To compare percentages, we use the formula: is / of = % / 100.
The lesson includes a few examples of how to find the “is” in this formula. The first example problem is 40% of 150 is ?. To find the answer, we first cross multiply the two numbers that are diagonal from each other (40 and 150) and then divide that number by 100: 40 x 150 = 6,000 / 100 = 60. The “is” in this problem is 60!
When we compare percentages, we use symbols to indicate their relationship. We use > (greater than), < (less than), or = (equal to). We can then put the formula and the symbols together to compare! The lesson includes a few examples.
In the first example, we need to compare 5% of 25 and 3% of 50. First, we cross multiply each side of the comparison: 25 x 5 = 125 / 100 = 1.25 and 50 x 3 = 150 / 100 = 1/5. Now, we can compare these two numbers: 1.25 is smaller than 1.5, so 1.25 < 1.5!
COMPARE PERCENTAGES LESSON PLAN WORKSHEETS
The Compare Percentages lesson plan includes three worksheets: an activity worksheet, a practice worksheet, and a homework assignment. You can refer to the guide on the classroom procedure page to determine when to hand out each worksheet.
INDEX CARD ACTIVITY WORKSHEET
For the lesson activity, each student will receive a colored marker and an index card. On the index card, they will fill in the blanks in the sentence “___% of ___ is…” and return the index card to their teacher. The teacher will shuffle the cards and place them around the room for students to find. Students will find two cards written in the same colored marker and compare.
PROPORTIONS PRACTICE WORKSHEET
For the practice worksheet, students will compare percentage proportions using <, >, or =.
COMPARE PERCENTAGES HOMEWORK ASSIGNMENT
The homework assignment asks students to teach a family member or pet how to compare percentages, creating their own examples. They will fill in the worksheet with the correct terms related to comparing percentages.
QUIZ
This lesson also includes a quiz that you can use to test students’ understanding of the lesson material. For the quiz, students will compare two percentages.
Worksheet Answer Keys
This lesson plan includes answer keys for the practice worksheet and the quiz. 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.
