Preschool Math: numbers greater than 10
1) First ED counted the number of animals.
2) Then she pulled out the same number of beads-one golden bead bar (10) + single beads. I made a big deal about the group of 10 beads being called her special ‘golden beads.’ She promptly fell in love with them!
3) Next she chose the proper digit and placed it in the ones column to make it “one ten and one” (for 11), “one ten and two” (for 12) and so forth.
If you’re interested in the printout packet I made of the seguin materials you can download them here. You can also buy a proper wooden seguin board (such as this or this teens and tens board), but I never used them enough with my older two to warrant the price.
I got a great question about how to learn more about Montessori method of introducing the teens and tens to your 3-6 year old.
There is a series of videos at ehow that shows a teacher using the seguin board and Montessori beads. Teen Board-Montessori video In the sidebar you’ll find related articles and links.
Another fabulous resource is the online Montessori album (teacher’s manual for ages 3-6) at moteaco.com. There you’ll find a whole series of lessons on how to introduce the teens and tens to your preschooler.
Hopefully that’s enough to get you started!
