About This Chapter

Share these fun videos lessons with your 6th-grade students as you teach them how to work with percents in mathematics. Scroll down to see suggestions for how you might incorporate these videos into your classroom instruction or homework assignments.

Standard: Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent. (CCSS.Math.Content.C.RP.A.3.C)

About This Chapter

Percent notation is the focus of this group of lessons. Completing these lessons will boost your students' understanding of how to express rates using percents and how to solve problems that include percents. Practice with real-life examples in these engaging videos as your students learn to apply taxes and discounts. These lessons feature topics such as:

  • The definition and application of percents
  • How to solve word problems including percents
  • How to calculate taxes and discounts

As students start to grasp these concepts they will easily convert between percent, decimal, and fraction notation with ratios and rates involving portions of 100. They will be able to pull essential information from word problems and organize it into an equation, solving for the unknown variable indicated by the equation. They will also be able to solve percent questions where either the part or the whole is missing.

How to Use These Lessons in Your Classroom

Incorporate these lessons into your classroom instruction

Watch these videos all at once or over several days (they are all less than 10 minutes long). After each video, discuss other real-world examples that the students come up with similar to those presented in the video. Complete the quizzes and chapter test either as homework or in class; perhaps the quizzes as homework and the test in class to gauge comprehension.

Nutrition label homework

After watching the Solve Problems Using Percents video in class, describe briefly the basics of nutrition labels. Focus on the percent of daily value figures and identifying which items they should avoid (excess fat and simple sugars), which they should moderate based on activity (protein) and which they should seek to max out (essential vitamins and minerals). Next assign the homework of recording the nutrition labels of 10 of their favorite foods, snacks, and drinks. Have them assess the healthiness of their food choices as a function of whether they are exceeding the limits they should avoid and meeting the values they should seek.

Classroom liquidation sale!

Create 'price' labels for several objects in the classroom and attach them to the objects. For each object assign a percentage that the product price is being reduced. Watch the Solve Problems Using Percents and Taxes & Discounts videos with the students and then let them know that the classroom 'store' is going out of business and must sell everything at hugely discounted rates. Break the class up into groups, give them a budget, and have them choose items to purchase that fall within their budget, taking note of how much they are saving in the process. Have them announce their list, how much they spent, and how much they saved and let the other teams decide how they made out.
