Pizza Fraction Fun (Digital Resource and Read A Loud)

Have some pizza fraction fun with these digital slides. They are absolutely no-prep and will get your students to identify fractions.

I love it when we can combine math and literacy. What fun it is to read a book and then work on some math. Well, I’m working on a new series that will help you introduce fractions through books. With each book I recommend, I will have Google slides that your children can practice a concept with.

The first in the series worked on seeing fractions in groups, and this is even reviewed in this book. But today we are mainly focusing on pizza. And learning that a numerator tells us how many parts are in a whole, and the denominator shows us how many parts it takes to equal a whole. 

Fraction Read – A – Loud

Today we jump in and begin reading “A Fractions Goal – Parts of A Whole”. 

Now I would always recommend that you read the book to your students. It is so much better that way because you can point out pictures, ask questions, and have discussions about the book. But if that isn’t possible for some reason – say social distancing – then you can watch it being read on YouTube .  

I love this book, with its rhyming words, cute pictures, and of course introduction to fractions. As you read through it, make a point to show the numerator and the denominator. Ask questions about how fractions are made, and how we can figure out which number goes where. 

Pizza Fraction Fun:

Now it is time to jump into some pizza fun. These google slides are a fun way to practice identifying pizza from pizza. 

Most of the slides just show a pizza, and the children get to drag and drop the numerator and denominator into the correct spot. With Google slides you will have to go back and check to make sure they are correct. 

There are a few slides that ask the students to label the numerator and denominator. Just an extra step to get them familiar with those fun math words. 

The Next Step:

Once your kiddos work through these digital learning slides, I highly suggest you try this activity that will expand on their knowledge of numerators and denominators. 

There is a printable version (which I prefer).

Learning about fractions can be fun, and pizza fractions are even more fun. I hope these resources help!

Build a Pizza Fraction Game

This post may contain affiliate links.

One of the most fun ways to learn fractions is with everyone’s favorite food, pizza!  This Build a Pizza Fraction Game is so much fun for a beginning fraction lesson for kids.

It’s also a fun one to pull out for pi day! Having a little pizza pie on pi day is always a good thing.

The build a pizza fraction game is one that doesn’t really feel educational because kids just enjoy playing it! Who doesn’t love to design their own pizza?

How to Play the Pizza Fraction Game:

The Build a Pizza Fraction Game can be played alone, in pairs, or in groups racing one another to finish their pizza first.

You will need a regular 6-sided die and a game piece for each player.

The slices of pizza are different fraction amounts. There are 1/2, 1/4 and 1/8 size pieces. Also included, are 8 different types of toppings: tomatoes, red onions, pepperoni, olives, ham, mushrooms, peppers and basil.

The goal of the game is to make a complete pizza with at least one of each topping on the pizza. You build your pizza right in the center of the game board.

Roll the die and move around the game board. You can collect toppings ,but they cannot be put on until you build a complete pizza.

Occasionally you will land on a space where you eat a fraction portion of the pizza which sets you back a little bit.

What the Pizza Fraction Game Teaches:

In this game, kids are learning basic fractions including whole, 1/2, 1/4 and 1/8. They also learn equivalent fractions a little bit when they recognize that 2 – 1/4 pieces equal 1/2.

The pizza fraction game is easy to put together and kids really have a great time with it!

My son was my tester and model for this activity and he had a blast building his pizza. He said multiple times during the game: “This is so fun!” I say that’s a good testimony!

So, if you are ready for some fraction fun, print out this game and get going!

Pizza Anyone? Introducing fractions (+ multiplying)

Welcome to Week 2 of  January’s Back to Math Basics  — a quick review of the basic math that you need to do everyday math. Answers to last Friday’s integers questions are at the end of this post.

When kids are first learning about fractions, teachers often turn to something that all but the lactose- or gluten-intolerant can appreciate — pizza! (And I can empathize with the allergy inclined. For you, imagine a dairy-free,  vegetable pie with polenta crust  — yum!)

This is for very good reason: Fractions are simply parts of the whole. When you cut a pizza into 12 equal parts you are creating twelfths. To count them, you’d start at one piece and count around the pizza (or in random order, makes no diff): one-twelfth (1/12), two-twelfths (2/12), three-twelfths (3/12)… all the way to 12-twelfths (12/12) or the whole pizza (1). Half of the pizza is six-twelfths (6/12) or one-half (1/2). A fourth of the pizza is three-twelfths (3/12) or one-fourth (1/4). Get it?

(Okay, so it’s really, really hard to write a blog post about fractions. In Word, I can depend on something call  MathType  to write fractions, which I’ll create for examples below. But in paragraphs, this doesn’t work so well.  So please bear with me!)

It might make sense to start with addition and subtraction, but in this case, multiplication and division is the better start. (Spoiler alert: You’ll use multiplication to add and subtract. Really.) But just like with integers, multiplying and dividing fractions are really, really easy.

So let’s go back to those pizzas. Let’s say your son is having a birthday party, and he wants to serve pizza. If each kid can eat 1/4 of a pizza and there are 12 kids at the party, how many pizzas do you need to buy? (Seriously, this is not as dorky a question as it might sound. I have had to figure this out  IRL .)

Are you actually multiplying two fractions here? Why, yes. Yes you are! In fact, any whole number can be written as a fraction — just use the number itself as the numerator (the top number in a fraction) and 1 as the denominator (the bottom number in a fraction). So…

Now, here’s the multiplication rule. Just multiply the numerators together and then the denominators together.

How easy is that? But what does 15/4 really mean? This is called an improper fraction — which just means that it’s got a numerator that’s bigger than the denominator. But it has a much, much bigger meaning — improper fractions are bigger than one.

How many pizzas is 15/4? Well this is easy too.

Fractions mean division. So to turn an improper fraction into divide the denominator into the numerator. But 4 doesn’t divide evenly into 15. In fact, 4 goes into 15 three times, with 3 left over. (Or as your third-grade self said: 3, with a remainder of 3.)

The whole number is the number of times 4 divides into 15. The remainder becomes the numerator of a fraction, and 4 stays in the denominator. Like this:

Whew! What this is means is that you need 3 and 3/4 pizzas. I don’t know of any pizzeria that delivers in this way, so round up to 4 pizzas, and you should be good to go.

That’s a lot of information. So here’s a quick summary:

1. Any whole number can be written as a fraction. Just use the number as the numerator and put a 1 in the denominator.

2. To multiply fractions, multiply the numerators together and then multiply the denominators together.

3. To change an improper fraction to a mixed number, divide the denominator into the numerator. The whole number answer is the whole number in the mixed number. The remainder is the numerator, and the denominator stays the same.

Show me (or better yet, yourself) what you’ve got with these examples. I’ll have the answers in Wednesday’s post. Questions? Ask them in the comments section.

Answers to Friday’s challenge questions: -30, -2, 5, 32, -14. How did you do?

"Coffins"

Here is a collection of difficult math problems with elegant solutions that possess a unique history.

• The main list of problems
• Problems submitted by others

The history of this collection

Sample solution, other links.

In the summer of 1975, while I was in a Soviet math camp preparing to compete in the International Math Olympiad on behalf of the Soviet Union, my fellow team members and I were approached for help by Valera Senderov, a math teacher in one of the best Moscow special math schools.

The Mathematics Department of Moscow State University, the most prestigious mathematics school in Russia, had at that time been actively trying to keep Jewish students (and other "undesirables") from enrolling in the department. One of the methods they used for doing this was to give the unwanted students a different set of problems on their oral exam. These problems were carefully designed to have elementary solutions (so that the Department could avoid scandals) that were nearly impossible to find. Any student who failed to answer could be easily rejected, so this system was an effective method of controlling admissions. These kinds of math problems were informally referred to as "coffins". "Coffins" is the literal translation from Russian; in English these problems are sometimes called "killer" problems.

These problems and their solutions were, of course, kept secret, but Valera Senderov and his friends had managed to collect a list. In 1975, they approached us to solve these problems, so that they could train the Jewish students in these mathematical ideas. We solved some of them. Here I present some of the "coffin" problems from my archive.

I invite people who faced "killer" problems to send them to me to add to my list.

Problem 31.

A quadrilateral is given in space, such that its edges are tangent to a sphere. Prove that all the points of tangency lie in one plane.

Solution. Begin by observing that each vertex of the quadrilateral is equidistant from the two points of tangency of the edges it is on. With that, put a mass into each vertex of the quadrilateral that is proportional to the inverse of the distance from that vertex to a point of tangency (of an edge it's in). Then the center of mass for any two neighboring vertices is the point of tangency of the edge they share. Then the center of mass of all four vertices should lie on the line connecting opposite points of tangency. That means that the two lines connecting the opposite pairs of points of tangency intersect, so all four of them lie in the plane those two lines define.
