This is a great activity that I used as an extension activity. In the activity, students first choose what they need to buy a new TV for: video game tournament, Netflix marathon, or Super Bowl party. They then solve for critical information about four televisions: original price, sale price, percent discount, and discount amount in dollars.
After all of that, students get to select which TV they would purchase, add a protection plan, calculate the percent increase of adding the protection plan, add the cost of shipping, and finally add the tax!
Advanced kiddos can certainly work this on their own, but I find it best to have students work with a partner on this activity. It is quite involved and brings up interesting conversations. Enjoy!
I could also see this being used as a form of assessment since it covers several real-life percent situations associated with making a discounted purchase.
(PS - To reduce paper waste, I used this as an online worksheet.I recommend either doing that or printing front/back and having them work in partners. You could also print a class set front/back, slide them into sleeve protectors, and have them use skinny dry-erase markers.)
