This mini-pack includes two foldables for interactive notebooks, and two real-world activities working with sales tax and gratuity (tip). Students will simulate real-world experiences of calculating sales tax at "Math-Mart" and calculating gratuity at "Mathies Restaurant". Check out the preview for more information, including notes for implementing in your classroom!
I've used these activities as a math center and in a small group. To save on colored ink, I just run off a few of the menus and department item lists and stick them in page protectors for students to share.
