1. Capture the attention of the learners by connecting them to the concept in a personal way. Have students solve a problem similar to 12 - 2 x 3 + 7. Gather and record all the different answers.
2. Guide students to reflect on the activity. Ask students to explain why so many students had different answers.
3. Give the learners a new and wider view of the concept by connecting to their personal knowing of the concept. Share the correct answer with the students. Challenge them to discover how the answer was found.
4. Provide an acknowledged body of information related to the concept. Explain Order of Operations. Practice with the four operations, then expand to the use of parentheses and exponents. Share the acronym, PEMDAS, "Please Excuse My Dear Aunt Sallie".
5. Provide a hands-on activity for practice and mastery of the elements of the concept. Students complete worksheets to practice working on the concept. After they have achieved partial mastery, students work with a partner and challenge another pair of students to play the game, "How the West was 1 + 2 x 3".
6. Learners apply the concept to a constructive project. Groups of students create their own game that also utilizes Order of Operations.
7. Refine and edit work. Students check work against the criteria listed in the rubric. Students play the game with another group to make sure it works. Changes are made if necessary.
8. Share the work with others. During "Game Day" students share their games with others. The games are then placed on the game table for use during free time.
