I read about this style of number cards in the book, Teaching Montessori in the Home: The School Years (Affiliate Link), and thought it was a really clever idea. Basically you just stack the cards on top of each other to make any number with each card representing either the thousands, hundreds, tens, or unit place. Then you can take a number (like 7401) and dissect it into its component parts (7 thousands + 4 hundreds + no tens + 1 unit). If you combine these cards with the Montessori Golden Beads, they become even more meaningful. I made a free, downloadable printout to make it extra easy to make a set of these cards, but you could also write the numbers by hand on cardstock or note cards cut to a workable size.
Recommended Age Range: Kindergarten and Early Elementary
Time Required: ~30 minutes
Cost: Practically free, though cardstock can be a little expensive if you have to buy a whole pack. However, you’ll only need 3 sheets.
- 3 Sheets of Card Stock (I used 110 lb weight paper, but any heavy paper would work. You could also use regular paper and laminate it after printing, but that would obviously be more time-consuming.)
- Number-Symbol Cards document (You might need a free Adobe Acrobat reader if your computer does not already know how to read pdf files.)
Supplies & Tools:
- Print the Number Symbol Cards document onto card stock.
- Cut along black lines.
There are many ways to use these cards. Since at present I work mainly with a kindergartener, we only use the tens and the units place cards, and take turns making and reading numbers. If you have Montessori bead material, you can use the beads to illustrate exactly what each number means.
