Lesson Plan Template:
Model Eliciting Activity (MEA)
The comprehension questions/readiness questions and reflection questions can be used as formative assessment (for questions, see the Readiness questions section). Comprehension and readiness questions will indicate whether the students understand the problem and the problem context, and reflection questions are meant to elicit students' thinking as they are working through the problem.
The comprehension/readiness questions are asked of students after they read the first client letter (see Reading Passage 1). The teacher can ask the class to respond to these questions and ensure understanding before students begin working with the data. Students' responses to the reflective questions can also indicate whether scaffolding is needed. The reflection questions are asked by the teacher as students are working in their groups on parts 1 and 2 of the MEA. These questions can reveal any misunderstanding or issues that students have as well as guide them to think about what they are doing.
Feedback to Students
The teacher can ask the students probing questions while they are working to ensure that they understand.
Why did you pick that answer?
What is your reason for doing it that way?
The students will demonstrate mastery upon completion of MEA. Please see rubric located in the Instructional Suggestions section.
The students will demonstrate mastery of the ELA standards with the final letter written to the client.
The students will
Compare, contrast, and convert units of measure between different measurement systems (US customary or metric (SI)) to solve real world problems.
Compare, contrast, and convert units within a measurement system (US customary or metric (SI)) to solve real world problems.
Develop a letter which conveys their reason for developing their process for ranking.
Support their process by explaining their reasoning in a clear manner.
Part 1 (Days 1 and 2)
Ask students the formative assessment questions for math content (see Formative Assessment) and provide a review if needed.
Students receive client letter 1 (Reading passage 1) and dataset 1, (provided in the Dataset 1 section).
The teacher can ask the readiness/comprehension questions (see Readiness questions) to the class or have students complete them individually on paper. After students understand the task, they can begin to work in teams of approximately 3-4.
In teams, students work on the problem and respond to the client with the requesteddeliverables.
As students are working, the teacher circulates to each team to ask the first set of Guiding/Reflective Questions and address any issues that may arise.
Teachers can provide guidance using the reflective questions to help students determine the important factors and start thinking about how they can present their solution.
Part 2 (Day 3)
Students receive the client letter 2 (Reading Passage 2) and dataset 2. (found in the Dataset 2 section), along with their work from part 1.
Teams test, evaluate, and revise their first procedure as necessary with the seconddataset and provide the requesteddeliverables as specified in the second letter.
If teams finish early, they can begin preparing their presentations.
After all of the teams have completed their second letters to the client, the teams will present their results to the rest of the class and classroom discussion will follow. (Rubric)
Why do you think that?
How do you know if you have an answer to the problem?
Would your selection work in a different situation?
What are the most important things to consider in your procedure?
What are the strengths and weaknesses of each?
Reading Passage 1
Owl B. Smart Bed and Breakfast is a new hotel opening up on South Beach. We have a lot of competition in that area so we want to ensure that we have the best breakfast in town. Orange juice is one the most important elements of any breakfast. We are trying to decide which orange juice we should serve. We need your team's help!
In order to come to a decision, we need you to rank the juices from best to worst. Here are the steps we have taken in the process of finding the best orange juice for our hotel. We have researched five orange juice companies and have evaluated them on four criteria: price, health, environment, and taste. We have provided you with a copy of these ratings.
Please look over the data and then develop a procedure for ranking the juices. Please write us back and tell us the order in which you ranked the juices and why. Also, provide us with a clear and detailed procedure for how your team ranked the juices from best to worst. In addition, please calculate the price per cup for each of the juices. Make sure that your team's procedure will work even if we decide to research and collect additional data on other orange juices. Thank you for your help!
Sincerely, Owl B. Smart President, Owl B. Smart Bed and Breakfast
Our team, _________________, has determined the following procedure for ranking:
The order that we ranked our choices from highest to lowest is:
What is the problem?
Who is the client in this problem?
Who are the customers that the letter is referring to?
What does the client need?
What do the customers need?
What do you need to include in your letter?
Why is the client asking for a procedure to select the best orange juice?
Reading Passage 2
Thank you for all of your hard work helping to create a procedure for ranking orange juices from best to worst. The same day we received your letter, we finished researching two more orange juices. Since we just received your letter, we have not had the opportunity to use your procedure. We would like for you to help us by making sure that the procedure still works with these new data and any additional data we might receive.
Please write us back and tell us the order in which you ranked the juices and why. Also, provide us with a clear and detailed procedure for how your team ranked the juices from best to worst. Also, if your team had to make any changes to your first procedure, please explain what you changed and why each change was needed.
Thank you again for all of your hard work! We look forward to hearing back from you so that we can make our final selection of which orange juice to serve.
Sincerely, Owl B. Smart President, Owl B. Smart Bed and Breakfast
