There are 2 different main dishes, 3 different side dishes, and 4 different drinks on Bridgette’s menu.
Bridgette would like to know how many combinations would be available to her
customers. Can you help Bridgette?
·
How many meal combinations can you
make?
·
Use words, pictures, tables, and/or a chart
to prove that you have all possible combinations.
·
Can you write an equation that would
help you determine how many total combinations you will have?
·
If
N= number of main dishes, X = number of side dishes, and Y = number of drinks, is it possible to write an equation that
would always work, even if Bridgette added another choice in one (or any) of
the categories?
Now see how we solved it!
Evan used a tree diagram and color coding to find his solution.
Margaret solved her problem using a table.
Griffin made an organized list.
Clara used a tree diagram. Notice that she identifies the "proof" that her answer is correct.
Kieran used two methods. Compare his equation to some of the others.
Problem solved! Lena is one happy mathematician!
Ireland takes a snack break!
Ireland made an organized list for the hot dog combinations then multiplied it by 2 to get the total combinations. Awesome work Ireland!
Jarod's equations. If Bridgette adds another main dish will his second equation still work?
Still working :) Check back tomorrow!
Update!
Day 2 of the "Bridgette Problem"
Lydia and Ella used a table. They seperated the "hot dog combos" and the "hamburger combos".
Griffin's Final Poster
Fantastic!
Like Ireland, Silas discovered that he just needed to figure out the total number of hot dog combos and then multiply it by 2 to get the total number of possible combinations.
After comparing Clara and Kieran's work, something pretty cool happened. Watch the video below to see Kieran, Ella, Evan, Griffin, and Silas discover and discuss the associative and commutative properties of multiplication.
