After I posted my Restaurant Math blog I heard from parents reminding me of more ideas. I will post these as they come in!
Ordering pizza-use fractions to discuss the slices and how many pieces everyone eats. You can also use fractions with young children when discussing ordering a pizza with two toppings. “Half” the pizza with cheese, and “Half” with pineapple and ham (my favorite). Hmmm…gotta go order pizza for lunch now!
