Learn a way to multiply larger numbers that is not typically taught in the traditional classroom. While most students are only taught one way to multiply, there are many different methods that have been used throughout places and time. Lattice multiplication is a method of multiplying that has been dated back to the early Hindus and Arabians.

Class will be structured so that the first 1-2 minutes students will introduce themselves. 
Then next 3-5 minutes will be used to explain to students that there are always many ways to solve problems in math. Although it might not seem useful now with calculators, it is beneficial to see different ways to solve math problems. Seeing different methods of problem solving helps students develop their own problem solving skills.
The following 10 minutes will be a teacher demonstration of how to do lattice multiplication.
As a group, we will then complete some examples together for the next 10 minutes. Students will be encouraged to ask for any clarifications. 
The next 10 minutes, students will be given problems to solve individually. Students will check their work the next 5 minutes. 
The final 3-5 minutes, students will be asked if they have any questions and their overall thoughts on this method of multiplication.

I believe that true learning happens when the learner is actively participating and engaged. Mistakes are encouraged in my classroom. I believe we learn more from mistakes because we become critical thinkers as we try to understand the process so that we understand why we made our mistake. I try to allow many opportunities for students to participate.

It is encouraged for students to have the multiplication table up to 12 memorized.
