Almost every time students or adults go shopping, they will find items that are on sale. These items have been marked down a certain percent. Almost everyone has to pay sales tax when you purchase items. This project will help students to see some applications of percent's in everyday life.
• To find the original price of an item given sales price and percent discount.
• To find the sales price of an item given original price and percent discount.
• To find the percent discount of an item given original price and sales price.
Students will find three different items that are on sale from an advertisement in the newspaper. The ad/documentation can only have two of the following: original price, sale price or percent of savings. It cannot have all three. Students will create a booklet containing the following information: a cover sheet, project summary, documentation of the ads, and a balance sheet.
This is a project that I created for my Honors Algebra I 9th grade class. It could easily be used at any grade that percent's are taught. My students attend a public optional (magnet) high school in Memphis Tennessee.
I am flexible about how they put the project together however I found over time that I don't allow internet ads. There were too many bogus ads when I accepted a printout from the internet so I stopped allowing internet ads. I bring newspapers from home for students to go through so they can't use the excuse "we don't get the newspaper so I can't do the project." I go into much greater detail on the project sheet. The download is the actual rubric/project sheet that I give to students.
The most amazing comments show up in the project summary. One of my favorites is when a 9th grader says to me "I never knew how to find sales tax before now, thank you for showing me how to find sales tax on something that I buy at a store." Also I offer extra credit for parent comments, this is to get parents to see what their child is doing in school and hopefully they will check over the project for mistakes. I get some of the neatest comments from parents.
Sometimes I think the project is too simple for a 9th grader but I am always amazed at their comments and in the long run it’s just a neat way to teach a real life concept to kids that they will use in their everyday day someday!
