Using only the numbers 1, 2, 3, and 5, and the operations +, -, *, and ÷, how many different numbers can you make? For example:

1 + 2 + (3 * 5) = 18

How many more can you make?

I can apply my computational skills to find equations that equal each of the numbers from one to one hundred.

This is called "Four Choices," and we will revisit this challenge periodically. You will work in groups of 3.

Our task will be to develop equations that equal each of the numbers from one to one hundred. You can use the four digits between one and nine that your group chooses, as well as the standard mathematical operations to accomplish this task.

For example, imagine my group chose the digits 2, 3, 5, and 8. I need to use these four digits and mathematical operations to create equations that equal one through one hundred. I could start with any number, but for this example, I will take the four digits I chose and create an equation that equals three: 3 = 2 · 3 + 5 - 8

There are three main rules for each equation:

• You can only use the four digits you chose.

• You must use all four of those digits.

• You cannot repeat any digits.

Let's make groups!

You will record your work on this sheet. First, your group needs to choose the four digits you will use for this challenge. You cannot change them once we start, so choose wisely!

You have the rest of today's time to see how many numbers you can get. We will stop periodically to share our progress and strategies. Ready. Set. Go!

How will I be graded in math class overall?

You will receive one of the following grades:

4 = A

3 = B

2 = C

1 = D

0 = F

Your grade will be calculated in the following way:

25% Classwork and Homework (based on completeness)

25% Formative assessments (weekly quizzes)

50% Summative assessments (chapter exams and projects - based on mastery)
