TTL Spring 2003: Electronic Showcase for Understanding by Design Unit by Pat Larsen Wilson Elementary School Rapid City, SD Multiplication In conjunction with Handheld Computer Project

Stage 2: Determine Acceptable Evidence PerformanceTask: Each student will be able to demonstrate concrete understanding of the concept of multiplication by building, drawing, or discovering arrays around the classroom. (The Math Stations are a new addition to my UBD. The concept for these stations arose from the fall 2002 ASCD on-line course entitled: Differentiating Instruction. These stations were created as tiered activities to address student differences.) Math Stations (Activity #2) In this activity, students build given multiplication problems concretely. They can do this several ways: Make arrays using paper plates to represent the groups and unifix cubes to represent the objects in a group. 5 x 4 Array 5 x 4 Array

Tiered Activities: Make arrays using beans and cups and paper plates and monkeys. 5 x 4 Array 6 x 2 Array Math Stations: (Activity #2) Showing multiplication concretely Make arrays using string and horses and fishing line and lures. 2 x 2 Array 4 x 4 Array

Tiered Activities: Drawing Arrays 3 x 8 Array (Multiplication as repeated addition) Math Stations: (Activity #3) Showing multiplication semi-abstractly Drawing Arrays 6 x 4 Array 2 x 6 Array

Tiered Activities: Arrays Around the Classroom 2 x 3 Array Math Stations: (Activity #4) Showing multiplication abstractly

Quizzes, Tests and Prompts: By using handheld computers, students have the capability of instantly “beaming” their results to their teacher. Through a handheld software program called “Quizzler Pro,” teachers have the capability of automatically exporting these test scores into their electronic grade book.

Conclusion Upon completion of this nine-week long unit, the vast majority of students at Wilson Elementary have not only experienced success in their understanding of the concept of multiplication and their acquisition of the basic facts, but have also come to recognize how multiplication is a critical step in their “Math Learning Stairs.” This vital step is essential for all future math learning.
