 * **Source** || **Objectives in Student-friendly Language** ||
 * ALCOS || We will discover that it takes slightly more than three diameters to equal the circumference of a circle. ||

 * Human Circle Activity ||
 * The students will share with a partner the results of the pizza boardwalk. Students will work in pairs to measure and predict the ratio of the circumference to the diameter of the circle. The students will record their findings on a record sheet and graph their circumference/diameter results. Each pair of students will have different size circles. ||


 * <span style="display: block; font-family: 'Century Gothic','sans-serif'; text-align: center;">Review/Assessment ||
 * The review of this activity will occur as a summary discussion where the students will have the opportunity to identify the symbol used to represent the value slightly more than three (pi) - approximately 3.14. ||
 * TTW will read the class the book "Sir Cumference and the Dragon of Pi". ||

The class will create a general conclusion about the ratio of the circumference to diameter and be introduced to the word that represent this ratio. ||
 * <span style="display: block; font-family: 'Century Gothic','sans-serif'; text-align: center;">General Description of Lesson ||
 * Students will measure circular objects to find the relationship between the diameter and circumference of a circle.


 * <span style="display: block; font-family: 'Century Gothic','sans-serif'; text-align: center;">Differentiation Supporting English Language Proficiency Levels ||
 * TTW use multiple representations to illustrate the lesson. During discussion, TTW verbalize what is written in the pizza boxes which illustrate the vocabulary as well. TSW also review and demonstrate the math vocabulary in an activity. ||


 * <span style="display: block; font-family: 'Century Gothic','sans-serif'; text-align: center;">Teacher Notes (process, procedure, safety, hints, tips…) ||
 * * TTW use technology to activate prior knowledge.
 * The student will be given different size circular objects for better data collection and all students must measure using the same unit of measure (centimeters).
 * Create chart for students to record their circumference, diameter, and ratio of the circumference and diameter results.
 * Create graph for students to plot the recircumference and diameter measurements relationship.
 * The class need a large open space to complete the Human Circle Activity. ||
