    Body mass index (bmi) Body mass index (bmi) Presentation Transcript

    • Please be patient while we ensure that everybody is logged on and their equipment is working correctly.
      We will begin shortly!
      Welcome to your Live Lesson!
    • 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
      What you will need for this lesson
    • 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
      Rules for the Live Lesson
    • Body Mass Index (BMI)
      An Introduction to your BMI and how to calculate it.
      By JenniStorck and Erin Markus
    • 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.
      Lesson Objectives
    • 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.
      What is BMI?
    • 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.
      What is a “healthy” BMI?
    • BMI Chart
    • The Formula that you will be learning today looks like this:
      [W ÷ (H)2] x 703 = BMI
      W= Weight
      H=Height
      The BMI Formula
    • 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!
      [W ÷ (H)2] x 703 = BMI
    • 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.
      Partner Activity
    • 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.
      Partner Activity
    • In this activity, you will use your own weight and height to figure out your own Body Mass Index. Please answer the following questions:
      What is my BMI?
      Is my BMI considered healthy or unhealthy?
      What can I do to improve my BMI, whether I am considered underweight or overweight?
      Please submit your answer directly to the instructor using our submission area. This information will not be shared with the rest of the class and is to learn about your personal health. Please contact your instructor if you have questions!
