In this 2 day course, children will form a concrete and abstract understanding of how to use the stamp game to solve static subtraction problems. Static subtraction is what we call subtraction that does not require any trading/exchanging.

Class Experience

The teacher for this class will either be Meghan, Sierra or Chantell. 

Meghan is the founder of World Montessori Academy, as well as having her MACTE Montessori Teacher training and Registered Early Childhood Educator. She has a warm and welcoming nature. Meghan actually went to Montessori when she was little! She fell in love that knew that when she grew up that she wanted to become a Montessori teacher... and look where we are now! Her dream came true and she can't wait to share her love of Montessori with you and your children! 

Sierra has been teaching for 8 years. She is a Montessori Master Teacher, certified and trained through the American Montessori Society (AMS) and MACTE. Teaching is her true passion. Guiding children through academics while creating a curious environment and fostering a true love for learning is what fulfils her. Sierra is so excited to be able to share her love of Montessori online with students around the world.

Chantell has been an Elementary Montessori for over 5 years and is a mother to two young boys. She loves to be outside in the warm weather and enjoys spending time with her little ones. In the classroom, Chantell encourages independence, and guidance when needed. She is so excited to teach your children!

All of the Montessori classes from World Montessori Academy are taught by certified, trained Montessori teachers. This ensures that you are receiving the best, authentic Montessori experience for your child. When looking for Montessori classes, please make sure that the teacher has one of the following trainings/certifications: MACTE, AMI, AMS.
Children will be required to have the stamp game, either the printable one that I will send you, or even better, the real stamp game! They aren’t very expensive, they tend to be around $30. My favorite Montessori material suppliers are Montessori Outlet (US) and Thinkamajigs (Canada).
20 minutes per week in class, and maybe some time outside of class.
