Serve up fractions in the most common context. Real-life photography makes them delicious. It represents 1 whole, 1/2, 1/3, 1/4, 1/6 and 1/8 values in 6 pizzas (24 pieces total) that stick to any magnetic surface for demonstration or student activities.
These pizza fractions helped me to introduce the concept of fractional parts to a whole, to my 3rd grade class. I keep them on the board and when students are comparing fractions, they use them as a resource. Very colorful.
