Pizza Party!

It's pizza time! Teach students the various parts of a whole by fitting together slices of a pie. Add toppings for addition and subtraction practice, and voila! That's one delicious lesson.

OBJECTIVE
Students will learn and practice the concept of basic fractions -- quarters, thirds, halves, and whole -- as well as simple addition and subtraction.

MATERIALS
Fiskars scissors, glue, colorful paper.

SET UP AND PREPARE

1.    Explain to students that a fraction is a way to count part of something. Have them think about everyday fractions: have they ever had a slice of pizza, or a whole pizza pie? Explain that today, they'll be learning about fractions--quarters, thirds, halves, and whole--using pizza pie slices!

2.    First review the parts of a fraction: the numerator and the denominator. The numerator is the top number in the fraction, and it represents the part of whatever it is you’re counting. The denominator is the bottom number in the fraction, and it represents the total number of whatever it is you’re counting.

3.    Give an example: if you're counting 1 slice of pizza in a pie made up of 4 slices, the fraction is 1/4. The number 1 (the slice you're counting) is the numerator, and the number 4 (the total number of slices in the pie) is the denominator.

DIRECTIONS

1.    Organize students into small groups. Give each group 3 large circles of paper (or pizza pies.) Together, cut the pies so that one is made up of 2 halves, another is thirds, and the last is quarters.

2.    Have students work in small groups to make their own pizzas using quarters, thirds, and halves.

3.    To practice simple addition and subtraction, have students cut out “toppings” from colored paper. Suggest making pepperoni, sausage, mushrooms, etc. and explain that each topping has a value of 1. Have students add and subtract toppings to each slice, recording the values on notebook paper.

4.    Hang the pizza fractions in your classroom to reinforce the lesson!
