Some time ago I printed from Montessori Print Shop place value cards for the Golden Beads. These are cards which come in sets of 3, depicting a value in its number form, written word form and an image showing the beads representing that amount.
For anyone who doesn't use the Montessori beads, these could easily be substituted for something similar such as base ten blocks, and you can find websites to print the large number cards I'm sure for free.
Anyway, here is what we did.....
1.) I gave K the value card in words.
2.) K then brought the corresponding bead material.
3.) I gave K the picture card to check she was correct.
4.) I then asked K to bring the correct value number cards...........
...........which she had to put together to show the correct number
5.) Finally, I gave K the number card so she could check she was correct.
