Shirts and Shorts What is a combination? A Combinations is two or more people or things that are combined to form a set. What are some things we could make different combinations with? Examples: ice cream cones menu combinations outfits safe or padlock combinations

Shirts and Shorts In today's lesson, you will explore combinations involving shirt and short outfits. Materials: Distribute the Shorts and Shirts activity sheet to each student.Shorts and Shirts Each student will need eight crayons in the following colors: red, green, yellow, blue, orange, brown, black, and purple. Problem: Each shirt must be a solid color, either yellow, orange, blue or red. Each pair of shorts must be a solid color, either brown, black, green, or purple. How many different outfits can be made? No two outfits should be the same. Record your predictions on your activity sheet.

Shirts and Shorts Discussion: Compare your results with others in your group. As a class, discuss the results. Students should have the following 16 correct combinations: Yellow shirt, Brown shorts Yellow shirt, Black shorts Yellow shirt, Green shorts Yellow shirt, Purple shorts Orange shirt, Brown shorts Orange shirt, Black shorts Orange shirt, Green shorts Orange shirt, Purple shorts Blue shirt, Brown shorts Blue shirt, Black shorts Blue shirt, Green shorts Blue shirt, Purple shorts Red shirt, Brown shorts Red shirt, Black shorts Red shirt, Green shorts Red shirt, Purple shorts

Shirts and Shorts Discussion: Was anyone’s prediction correct? If so, what was your reasoning behind your prediction? Tree Diagram: In addition to the organized list on the previous slide, you could also make a tree diagram or table to solve this problem. For a tree diagram, start with the options for the shirt color and list them: Next, think about what color pants could be worn with the yellow shirt? Could those same colors be worn with all the other shirts? Yellow Orange Blue Red

Shirts and Shorts Tree Diagram: On your paper, a tree diagram may look something like this: Yellow Orange Blue Red

Table: Another way to organize data is to create a table. First, list the possible shirt and short choices. Then, Fill in the table. : Shirts and Shorts

Table: Your table might look like this on your paper. : Shirts and Shorts

Do you notice a general rule or pattern? Could we use multiplication, division, addition or subtraction to solve? How did your prediction compare to your actual answer? How do you explain this? Which method would be more efficient for finding the total number of outfits: multiplying, drawing a tree diagram, or making a table? Which method would be more useful for identifying the different combinations (outfits) possible: multiplying, drawing a tree diagram, or making a table? Shirts and Shorts
