Happy Meals and Math

I'm envisioning a double lesson here. Proportions & Volume/Area of Irregular Shapes (with a built in lesson, if you would like, on choosing the right quantity of food per serving).

 Foremost, have your students bring in a happy meal box sometime within two weeks prior to the class, labeling everything that came in the box on the inside of the box with their name. You may want to swing by your local McDonald's and ask for extras for those who forget (don't forget to bring your teacher badge).

Next, you can go here and figure out the calories of each item. Or download the pdf

Next, have your students figure our what the proportion of calories in one Happy Meal is to their daily allotted proportion of calories per day , of which 2000 is probably a safe estimate.

Happy Meal/Calories Per day


Looking at the shape of the Happy Meal box you can see an irregular figure

Thus, have your students attempt to calculate the Area of the sides or Volume of the box.

Good Luck!
