5. Guided Practice: • Students self-assess their homework • Students peer-evaluate their partner’s data analysis to see if it was correct, accurate, and followed the requirements of the project 6. Closure: Have students preliminarily reflect on their findings; exit ticket 7. Independent Work: Check data and graph 8. Resources: graph paper, Algebra 1 text, rulers, colored pencils, graphic organizer Day 4: 1. Objective: • Students will be able to graph a data set • Students will be able to use a formula to calculate percents and peer evaluate • Students will be able to communicate findings to class 2. Standards: Students can use proportions and percents to graph reallife data collected 3. Anticipatory Set: • Students sign up for a time slot to present data 4. Teaching Presentation: • Students share their findings (data and graph) with the class, including self-evaluation of their work 5. Guided Practice: • Students answer reflection questions from Discussion Group and post to appropriate forum 6. Closure: Students write 3 things they learned, 2 things they liked, 1 thing they thought could be better about the project 7. Independent Work: none 8. Resources: timer, camera to photo student projects, computers, reflection questions, website

30 Our class experience... The Birthday Paradox was fun for students because they were able to poll their friends on birthdays. They analyzed the birthday data to see if it matched the project’s claim: 1 in 23 Our class data:
people will have the same birthday. In our own class of 30, 4 sets of 2 people shared a birthday! Students enjoyed the independence of posting onto a forum. Many knew how to use a forum already. The disappointing part of this project was that we were the first class to participate and the only one. Still students published their work and were able to share it with their parents and friends they had polled.

Our Class Data
We love marshmallows! Or at least we did before this project! The students loved the competition involved in this project. It really was entertaining to participate and the students will not stop talking about it in the classroom. We were the first class to participate in this project for the year so we had to alter part of our lesson plan, which involved looking at the data from other classes and graphing it. Instead, we graphed our own data only. Next time, I would have students hold up a sign showing how many are in their mouth in the picture. I also would ask the project designer to add more of a global component as the students did not have to get on the computer during the project.

*Notice of Change* The Marshmallow Project replaces the original GLP in this eNotebook We Are Family!. I chose to change to the Marshmallow Project because it supported the focus of my math department this year, which is AIMS review (Arizona Instrument for Measuring Standards – state testing). I would like to try We Are Family! another time, especially now that I have experience implementing GLP’s in the classroom.
