#### Transcript of Making Organized Lists and Diagrams - Problem Solving Strategy

Making an Organized List Problem Solving Strategies for Word Problems When solving a problem, don't just think, write something! Draw a diagram or make a list!
It is often obvious when you should draw a diagram. And it is often obvious when you should make a list.
Take a very simple example: putting things in order. Ten people arrive at a party. If the party is in Turkey , each person kisses every other person twice, once on each cheek. How many kisses are there? Make an organized list for the following problem... You and a friend decide to eat dinner at a pizzeria. Here are your options of pizza toppings:
Cheese: mozzarella or parmigiana
Veggies: onion or bell pepper
Meat: sausage or pepperoni Try this one! A tree diagram is a useful type of list.

For example,
the game of dominoes is played with black and white tiles.
Each tile is divided into two halves and on each half a number from 0-6 is represented in the form of dots.
Each tile contains a pair of numbers and each pair appears only once in a complete set.
How many tiles are there in a complete set of tiles? The solution to this problem can take the form of a tree diagram. Lists and diagrams There is a common saying,
"Don't just stand there, do something!" For example:
The letters ABCD, can be put into a different order: DCBA or BADC. How many different combinations of the letters ABCD can you make? To answer this question, obviously, you have to make a list. Begin by making a list of the people at the party.
How will you identify each person?
With numbers? Letters?
How many kisses will the first person have?
The second? Third?

How many kisses are there total - can you simplify it with numbers? How many different combinations of pizza can you and your friend make? I will give you the beginning of a tree diagram to start with...see if you can finish it to solve the problem :D
