Montessori Stamp Game *Exchanging Practice* for Lower Elementary Learners

**IMPORTANT: 
Is your learner ready for this class? Can your learner:
- count by tens and correctly identify the numbers 1-100? 
- build the physical quantities of golden beads, base 10 material, or stamp game stamps asked for if given a number like 5,239?
- add numbers in each place value without needing to move to the next place value*? (*For example: 3,482 + 1,415 = 4,897. We call this "static" addition and subtraction in the Montessori world. No "borrowing" or "carrying" is needed.)

If you answered yes to all of the above, then you are in the right spot!

The stamp game is a great way to practice numbers through the thousands place value and the math operations: addition, subtraction, multiplication, and division. Even if you have never heard of Montessori, this one, hands-on material might make all the difference in the world with your first or second grade learners. 

We will be working on "exchanges" in each operation, or "dynamic" addition, subtraction, multiplication and division. (Montessori doesn't use "carry/borrow" -- it's all just an "exchange" at the bank.)

In this ongoing class, we will cycle through all of the operations over the course of 10 weeks. Didn't catch the first class? No problem! Since we are always working on the process of exchanging from one place value to the next, join us at any point, for any operation!

I use a shared screen in class that shows me using the Stamp Game and writing on my own white board. I'm expressive and I encourage enthusiastic participation. I keep the class size limited to a maximum of 5 learners so that everyone can participate. I prefer to leave learners unmuted, but if a background is too noisy, I will ask that they mute unless they are actively speaking.

Learners will need to have their own stamp game or work with a virtual stamp game *on a different device*.  Learners should be set up in an area that is free from distractions and they can tilt their screen down so that I can view their work area as needed. Learners should have a white board and marker to record their work as we go.
