-690397-693682Lesson Plan2010 – 2011Instructor Name: Miss LachesisObjectives:SWBAT calculate the number of calories they need per day.This will serve as a review for the following skills: conversion between units, plugging in numbers for variables, decimals, order of operationsMaterials, Texts & Reminders:Power pointWorksheetCalculators (to check work)NOTE: Powerpoint and worksheet attached!Key Points:Conversions, decimals, variables, order of operationsAssessment/Check for UnderstandingWorksheet collectedHigher Order Thinking Questions/Big Question:How can we use this knowledge to make healthy decisions in the future?Do Now:Brainstorm four ways math is useful in real life. Be creative!How tall are you in inches? Remember: 1 foot=12 inchesLesson:Review Do NowRead through introduction or worksheet together (on powerpoint)Go through example quickly on white boardGuided Practice: Go through step by step on powerpoint as students use their own information.Independent Practice: Have students complete follow up questions, will finish for homework.NOTE: Be sure to keep having disclaimer that this is only an estimate of how many calories they need each day. As teenagers who are still growing they may need more than people who are done growing. Also, the more muscle you have the more calories you burn. HomeworkAnswer the follow up questions at the end of the worksheet. This may be started in class.Modifications/Accommodations/Differentiated Instruction:Read problems out loudOne on one attention when needed with repeated reviewStep by step instructions in worksheetIEP Students:Visual AidsModified testExtended TimeRepeated ReviewStudy Aids/ManipulativeSmall Group InstructionGuided NotesShortened AssignmentsAdvanced Students:EnrichmentCompactingTiered AssignmentsName: Period: Real Life Math: How many calories should I eat each day?Introduction:Vocabulary:Expenditure: How much you use or expend.Metabolic/Metabolism: The chemical processes by which cells produce the substances and energy needed to sustain life. The rate you break food down into energy.The first step in designing a personal nutrition plan for yourself is to calculate how many calories you burn in a day; your total daily energy expenditure (TDEE). TDEE is the total number of calories that your body expends in 24 hours, including all activities. TDEE is also known as your "maintenance level" because it is how many calories you need to keep your weight the same.One of the most accurate methods for calculating TDEE is to determine basal metabolic rate (BMR) using multiple factors, including height, weight, age and sex, then multiply the BMR by an activity factor to determine TDEE. BMR is the total number of calories your body requires for normal bodily functions (excluding activity factors). This includes keeping your heart beating, inhaling and exhaling air, digesting food, making new blood cells, maintaining your body temperature and every other metabolic process in your body. In other words, your BMR is all the energy used for the basic processes of life itself.Stop and Jot: What does our BMR tell us? What is the difference between BMR and TDEE?Formula to determine BMR:Men: BMR = 66 + (13.7 X wt in kg) + (5 X ht in cm) - (6.8 X age in years)Women: BMR = 655 + (9.6 X wt in kg) + (1.8 X ht in cm) - (4.7 X age in years)Stop and Jot: Before plugging in numbers what do you need to do? What information do you need to find?Find Basal Metabolic Rate (BMR):Step 1: Conversions!Convert your height from inches to centimeters.Note: 1 inch = 2.54 cm.Convert your weight from pounds (lbs) to kilograms.Note: 1 kilogram = 2.2 lbs.Step 2: Plug into equation for BMR and solve using order of operations. See example below.Men: BMR = 66 + (13.7 X wt in kg) + (5 X ht in cm) - (6.8 X age in years)Your BMR:Example: You are femaleYou are 30 yrs oldYou are 5' 6 " tall (167.6 cm)You weigh 120 lbs. (54.5 kilos)Your BMR = 655 + 523 + 302 - 141 = 1339 calories/dayD.) Calculate your Total Daily Energy Expenditure (TDEE). Now that you know your BMR, you can calculate TDEE by multiplying your BMR by your activity multiplier from the chart below: Activity MultiplierSedentary = BMR X 1.2 (little or no exercise, desk job)Lightly active = BMR X 1.375 (light exercise/sports 1-3 days/wk)Moderately active = BMR X 1.55 (moderate exercise/sports 3-5 days/wk)Very active = BMR X 1.725 (hard exercise/sports 6-7 days/wk)Extremely active = BMR X 1.9 (hard daily exercise/sports & physical job or 2X day training, i.e marathon, contest etc.)() Your BMR x () Your Activity Multiplier= () Your TDEEYour TDEE= How many calories you should consume each day!Follow Up Questions:Were you surprised about your TDEE?Why is the equation to find BRM different for males and females? How are you going to use this information in the future? What would happen to your TDEE if you increased your activity level? What happens when you consume more calories than you need? Less calories? Find the amount of calories you will need (your TDEE) when you are 45 years old. Assume you are the same height and weight and spend the same amount of time exercising.Step 1: Find BMR. Don’t forget to convert your weight and height and make sure to properly use order of operations!Men: BMR = 66 + (13.7 X wt in kg) + (5 X ht in cm) - (6.8 X age in years)Step 2: Find TDEE. () Your BMR x () Your Activity Multiplier= () Your TDEE How does your answer above compare with your current calorie needs? Why do you think that is? What are other things you want to learn in math class? REMEMBER THIS NUMBER FOR NEXT FRIDAY!Awesome quote: “Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.” ― Albert Einstein ................
