**THREE DIFFERENT METHODS OF MULTIPLYING (ONE LESSON)**

Overview:

Students learned three multi-digit multiplication methods (Lattice, Russian Peasant, and Visual Multiplication Methods). Following the lesson, students were advised about appropriate ways to discuss alternative problem-solving methods with their teachers.

Objectives:

- Master 3 alternative multi-digit multiplication methods.
- Recognize there can be more than one way to solve a math problem.
- Compare different multi-digit multiplying methods and analyze the efficiency of each method in relation to the problem provided.
- Learn how to follow directions and learn how to communicate effectively when you have different solutions to a problem.

Resources and Opportunities to Explore More:

Students were encouraged to teach their parents the three methods. Students may enjoy timing themselves to see which method is the most efficient or researching why each method works. The procedure and practice problems for the three multiplication methods can be found at the following sites:
