Graphic Organizer: Lattice Multiplication, Partial Product
Multiplication and the Standard Algorithm.
Self Checking Activity
One of the big common core changes is that students are expected to be able to deconstruct common algorithms and explain how they work. This lesson teaches Multiplication 3 ways: Lattice, Partial Product and the standard algorithm. Students are supported with graphic organizers which break things down step by step. Each portion of this lesson contains practice problems for students to test out each of the multiplication methods. This lesson concludes with a self checking activity, which allows students to examine their own work for mistakes.
You will be impressed with the results.
