Students will work in pairs to build a solution with toothpicks or use the computer model to create their solutions. Students will be required to keep a log of their solutions for use in their write-up. Student pairs will meet with another pair of students in order to share and discuss solutions discovered. It is important that all groups share their methods and reasoning for solutions with groups in order to promote peer tutoring. The sharing of ideas will also create a deeper understanding of students' own thought processes and expose them to the ideas of other students that may not have occurred to them.
Sharing also develops a confidence in students' abilities.
Students will break up to work individually. After completion of write-up, students will share their papers with another student to score them based on the Student Scoring Guide . After scoring each other's papers, students will informally talk with each other, explain the scores they gave their peers, and ask questions about the scores they received from their scorer. All papers are turned into the teacher for scoring based on the Official Scoring Guide .
