Welcome! This page contains my work fromEMT 668, EMT 669, and EMT 670. I hope that you might find something that is useful for your classroom.

The essays and investigations below were created in EMT 669 with my partner Ashley LIttle. You might find something you can use.

Essay One - "How much does a brick and a half weigh..."

Essay Two - An investigation of Napolean's triangle

Essay Three - The gingerbread problem

Instructional Unit Two - Translations Lab

Instructional Unit Three - Rotations Lab

Instructional Unit Four - Square Root Lab

Instructional Unit Five - Functional Shift Lab

The following lessons and activities are meant to be used with a Pre-Algebra class. We are using the

The first couple of days, I like to get the students familar with how
to use the TI-34 calculators. It allows them to get "comfortable"
with the technology they can use every day and review the mathematics at
the same time.

**Explanation of TI-34 lab**

**"Getting to know your calculator"
lab **

This chapter is a good time to get the students exposed to the TI-81
and its many capabilities.

**Section 1-1 "Order of Operations"**

**Section 1-2 "Variables and Expressions"**

**Section 1-5 "Variables and Equations"**

**Section 1-10 "Inequalities"**

In this chapter, students are using both the TI-34 and TI-81 calculators
to look for patterns.

**Section 2-1 "Integers and Absolute Value"**

**Section 2-7/2-8 "Multiplying and Dividing
Integers" **

A brief section on finding area and perimeter of rectangles is introduced
in Chapter 3. This is a perfect time to get the students introduced to GSP.
The following is a handout you can pass out to students to introduce them
to some of the basics.

**An Introduction to Geometer's Sketch Pad**

**Section 3-6 "Area and Perimeter"**

In this chapter it is important for students to become comfortable with
exploring. They should be looking for patterns and also generalizing.

**Section 4-2 "Powers and Exponents"**

**Section 4-5 "Greatest Common Factor"**

**Section 4-7 "Least Common Multiple"**

It is important for the students to know how to use the "fraction"
key on the TI-34 calculator. However, a much better approach to teaching
how to add and subtract fractions is to let them enter the problems in the
calculator and then figure out **how** the calculator gets the answer.

**Section 5-6/5-7 "Rationals: Adding
and Subtracting Rational Numbers"**

Once again, the technology can be used to work "backwards"
and identify what steps were taken to arrive at a particular answer.

**Section 6-3/6-6 "Rationals: Multiplying
and Dividing Rational Numbers"**

This is where my **other** project begins. My EMT 670 project was
much more work than I expected. Therefore, this project is a continuation
of my 670 project.

This chapter provides an overview of linear equations. I like to spend
the time having the students becoming familiar with the capabilities of
both Geometer's Sketch Pad and Algebra Xpresser.

**"Using GSP to graph linear equations"
**

"Using Algebra Xpresser to study perpendicular and parallel lines"

This chapter deals with ratios, proportions, and percentages. I find
this a wonderful time to expose students to the uses of the spreadsheet.
This was designed for Symantec Greatworks, but could be easily used with
any spreadsheet program.

**"Worksheet for M&M lab"
**

**"Using the TI-81 to compute statistics"
**

**Because this chapter deals with probabilities, it is a nice time to
show the students how to use their calculators to generate random numbers.
They can use the calculator to simulate the toss of a coin or the roll of
a die. The wonderful part is that you do not have to worry about dice or
coins flying all over the classroom!
"Dice simulation activity"

**The students should feel comfortable using GSP by now. This is a wonderful
chapter for students to do lots of exploration!

not used already)**

**Students should be exposed to the internet right from the beginning.
A nice application is to have a student get the math quote of the day from
this internet link. This site is provided by Furman University.

day!

**Here is another source students can access that gives a complete index
on famous mathematicians. Once there, you can access the mathematicians
that were born on that particular day. This site is provided by St. Andrews
College in St. Andrews, Scotland.
