**Project and Presentation on Linear Equations**

The students are required to create a presentation similar to the 'Traveling with Linear Equations' activity that we complete as a class. The project will give the students experience using a computer and an online site to help organize their knowledge and information. The students will also have to use some creativity to come up with scenarios that can be represented by equations.

**Word Problem Example**

Students must learn how to analyze word problems involving mathematics. Some important things to remember is that it helps to take the problem one sentence at a time, there might be irrelevant information in the problem that you do not need, and it often takes more than one time reading the problem to figure out what it is asking. Also, it is extremely important to be specific when answering word problems. For instance, if the question asks for the total cost of a product, the answer is not just a number. It must be represented in terms of money since that is what the question is looking for.

Example: Meredith is at the mall shopping, and she found a sweater for $25.00 plus a 7% sales tax. After she buys her sweater, she has $43.25 left. How much money did Meredith start with?

*The student will only receive full credit if all of the information above is set up and solved correctly. The student will receive half-credit for setting the equation up correctly but messing up the mathematical steps in solving the problem. The student will also only receive half-credit if they do not specify what their answer represents.

Example: Meredith is at the mall shopping, and she found a sweater for $25.00 plus a 7% sales tax. After she buys her sweater, she has $43.25 left. How much money did Meredith start with?

- Discussion: How do you write a % as a decimal? How to we find sales tax for an item?
- Equation: x=25+(25*.07)+43.25
- Solve for x: parentheses first (25*.07)=1.25
- Addition from right to left: 25+1.25+43.25
- Meredith began her shopping with $70.00

The student will receive half-credit for setting the equation up correctly but messing up the mathematical steps in solving the problem.

**Multiple Choice Questions**

There are two type of multiple choice questions assigned within the unit. The first type is an opportunity for the students to show me that they understand the meaning of a mathematical term. For example,

Any symbol, usually a letter, which could represent a number is a/an...

a) equation

b) variable

c) expression

d) symbol

The second type of multiple choice question tests the comprehension of the mathematical material learned within the unit. For example,

Which equation is written in slope-intercept form with a y-intercept of 5?

a) y=5x+2

b) x=3x+5

c) y=14x+5

d) x=5y+15

*In both instances, the students must circle ONLY one answer. If the student selects the correct answer, he/she receives full credit for that problem. If the student choose any of the three wrong answer choices, then no credit is received.
