CBT Math Mini-Lesson Activity Template General/Contact Information: Name: Jacqueline Roberts Email: email@example.com School: Technology Training Center Grade Level: 7 Subject: Math Surveys, Statistics, and Patterns Specific Skill: An Introduction to Measures of (Algebra, Geometry, Trig, Calc, etc) Central Tendency Activity Title: “THE POWER OF DATA” - How is Central Tendency Used? Lesson 2-3 class Duration: sessions GLEs #31 Analyze and interpret graphs, and determine which graph is the most appropriate type of graph to use. (D-2- Addressed: M) #32 Describe data in terms of patterns, clustered data, gaps, and outliers. (D-2-M) Mini-Lesson Procedure: Objectives: Objectives: Measures of Central Tendency (list all that apply) 1. The students will identify characteristics of data distribution. (mean, range, clusters, outliers, and gaps). 2. The students will compare characteristics of data in order to make decisions and predictions. 3. Present findings in a PowerPoint Presentation. Procedures: Type in the cell below. Essential Questions: 1. What is the significance of identifying clusters, gaps, and outliers in data? 2. Explain how an outlier affects the mean in a set of data. 3. What affect does changing one data value have on the measures of central tendency – the mean, the median, and mode? Vocabulary Bingo - students will be allowed to pair up and play vocabulary bingo with vocabulary words as a form of review and to continue helping students become familiar with unit terms. Intro to Lesson – Address GLE’s and Objectives of the lesson Pre-Assessment for Measures of Central Tendency Activities 1. Pre-Assessment: The teacher will pre-assess students’ knowledge of mean, range, clusters, outliers, and gaps. 2. PowerPoint as a teacher tool: The teacher will present the iLEAP warm-up, P.O.D., a review/teaching video from Unitedstreaming, Glencoe transparency, other lesson samples as needed and close with a 3-2-1 summarization. 3. Students will watch United Streaming video clips (Segments A, B, and C) applying real world examples of how measures of central tendency can be used. They will take notes from each segment to observe the application of finding the mean, mode, median, range, clusters, outliers, and gaps in a set of data used to interpret and give data more meaningful results. (use foldable handout here) Real-world example A: Scenario- Line Plot Video Students will view real-life application of the use of a line plot. Then teacher will pause video and students will create a line plot of their own from the data given, discuss the range, and find the mean, mode and median from the line plot. Real-world example B: Scenario-Stem and Leaf Video Students will view real-life application of the use of a stem and leaf plot to find the weight of dogs. Teacher will pause video to check for understanding while students create a stem and leaf diagram from the data given on the clip. Real-world example C: Scenario – Cluster and Gaps Video Students will view real-life application of identifying clusters and gaps from finishing times of races. Teacher will then pause video to check for understanding before formal assessment of all three graphic representations. After monitoring and determining student needs the teacher will provide more examples (these examples can be taken from Glencoe transparencies already on the PPT or other.) 4. Teacher will then hand out formal assessment. 5. As the lesson continues teacher will introduce collaborative group assignment. Students will work in groups of fours or fives to complete assignment Group Activity Group 1 Students will work at computer stations Group 2 Students will make stem and leaf diagrams Tasks: to collect data exploring the or line plots from Inspiration to record data. relationship between grams of fat and (identify what each grams of protein in menu items at group will do-at least 2 various fast food restaurants. groups are required) Group 3 Small group will collaborate to create Group 4 Small group will interpret data from graphs graphs for each restaurant showing the and create a power point to present to grams of fat against the grams of class their findings. protein in individual servings of lunch and dinner items. 5. Collaborative Groups- Original Scenario for students’ technology product- This activity explores the relationship between grams of fat and grams of protein in menu items at various fast food restaurants. Students will go to www.caloriechart.org (gives specific food items that you buy at the grocery) www.mcdonalds.com or www.wendy’s.com (gives all menu items in chart form) www.burgerking.com (you have to choose each menu item to get information) and make a copy of the calories chart for the students to use. From copies of calories chart students will create stem-and-leaf plots, line plots or other graphic organizer to arrange data. As a class they will create 3 double bar graphs (one for each restaurant) showing the grams of fat against the grams of protein in individual servings of lunch and dinner times sold at various fast food restaurants. 6. Student groups will complete and present a PowerPoint presentation which includes: graphics to illustrate their findings of the grams of fat and grams of protein in menu items at various fast food restaurants. They will determine the mean, mode, median, range, clusters, gaps, and outliers of data. (Inspiration or Microsoft Word can be used to make graphic representations. Then interpret data to make logical reasoning about how healthy we eat when we dine out at these places.
