It might be a close race, but I think students might like their phones, tablets, and gaming consoles more than school. The enjoyment I see from kids at my part-time job (Best Buy) can SOMETIMES exceed the excitement I see when I'm teaching linear or quadratic relations...okay, all the time. Depending on the course you're teaching, it can be a good idea to incorporate a weekly flyer into your class, to discuss discounts and better deals. Around this time of the year, flyers at any retail store are going to be pretty thick, so you have many options to choose from to answer the question: "what is the better deal?".
I've used this activity in a MEL3E night class, where I grab a few flyers and have students work in partners or a group of 3. I ask specific groups to tell me what is the best deal with respect to percentage discount and not actual price. I'll give one group laptops, another televisions, appliances, etc. It serves the purpose of students practicing working with percents, and also lets me know what the solid deals are (and yet still procrastinate on my Christmas shopping). At this time last year, my students (many above the age of 30) were gearing up for Christmas, so having them use a real flyer, instead of a made up worksheet, made this assignment more appealing. I'm sure many teachers have done this. I can give credit to the customers that always...always...ask: "which is the better deal though?".
Have a great day gang.
