Wooden Hierarchical Material - Number Cards

This material is a clear indicator of the differences between primary and elementary, even with the same material. It is also a perfect example of how the outward appearance of Montessori changes with each plane of development - so for those who jump ship after primary because they instinctively know that the primary experience is not appropriate for their second plane child, here is just one teeny tiny example of how Montessori addresses those very needs. 

At primary, the children can receive this presentation – it uses place-value colored number cards with spaces between the hierarchies, NO commas. These cards are available for download in a number of locations – free or for purchase – or can easily be handmade.
DIRECT AIM: focus on place value and the new hierarchy (millions) - counting the zeroes. This age does not need the comma for this presentation. (they do get the comma with the dot game and can use the comma with the division with racks and tubes work)

At elementary, the child should get this work again (or for the first time), because now, there is a new component: The Comma. The primary level colored cards can be used, just add a green comma after each number, such that when the cards are stacked in number formation, you have the following number:

1, 111, 111 

Those of you who have been following the recent blog posts and various discussions may recall one more aspect: some elementary albums describe the elementary number cards as being written in black (and still with a comma).

FINAL RESULT in the Real World: 

• Primary: colored, no commas 
• Elementary: colored OR black numerals, with commas to match (either green or black)

Homeschool option:
Take the cards from the Elementary Bank Game cards if they are laminated, use a dry-erase marker to write in the comma for this presentation; then remove it for Bank Game work.
