### Body mass index (bmi)

1. 1.  Please be patient while we ensure that everybody is logged on and their equipment is working correctly.  We will begin shortly!
2. 2.  You will need to be logged on to Adobe Connect  You will need a computer with a microphone and speakers  You will need to have a piece of paper and a pencil with you to work problems on your own  You may use a calculator for math problems
3. 3.  Please be patient when using audio and visual online tools. We may encounter problems, but we will work through them as fast as possible.  If you have a question, please choose the “Raise Hand” Icon and wait to be addressed.  DO NOT try to talk over someone else talking, it can affect how others hear the lesson  If you are having technical problems, let the instructor know by either raising your hand or typing in the chat window. We will address the issue as soon as possible.  Do not use the whiteboard feature for doodling, unless the instructor allows it for fun.  Write clearly on the whiteboard
4. 4. An Introduction to your BMI and how to calculate it. By Jenni Storck and Erin Markus
5. 5. The student will:  Know that BMI means Body Mass Index  Demonstrate how to figure out a BMI by performing a mathematical equasion  Work with a partner to solve a BMI “real-life” scenario problem  Calculate their own BMI and determine if their own BMI is in a safe range.
6. 6. BMI means Body Mass Index and is used to calculate a healthy weight range from underweight to overweight people. BMI is often used by doctors, nutritionists, and fitness professionals to determine the best diet and exercise program for an individual.
7. 7. Once your BMI has been calculated using a mathematical formula, you can determine if your BMI fits in a healthy or unhealthy range by using the BMI Chart.
8. 8. The Formula that you will be learning today looks like this: [W ÷ (H)2] x 703 = BMI W= Weight H=Height
9. 9. Step 1: Square the height of the person (in inches) Step 2: Divide the person’s weight (in pounds) by the squared height Step 3: Multiply that answer by 703 Step 4: Now that you have the person’s BMI, you can now look at the chart and find out if it is a healthy or unhealthy BMI! ** WRITE THE EQUASION DOWN ON YOUR PAPER BECAUSE YOU WILL BE USING IT TO DO THE NEXT ACTIVITY!
10. 10.  For this activity, you will work with your partner in your own chat room to solve the problem on the next page. Once you are finished solving the problem, we will share our completed problem on the whiteboard with the other groups.
11. 11. Sarah is 14 years old and feels she is overweight. She visited a nutrition counselor who calculated her Body Mass Index to determine if she is considered overweight. Sarah is 5 feet 3 inches tall and weighs 125 lbs. What BMI did the nutrition counselor come up with for Sarah? Is this considered overweight, normal, or underweight on the chart? Please post your completed math problem on the board and your answer to the question.
