So I've made a decision - we are going to drop the Red/Yellow/Blue scheme. I understand that presenting the letters to the children in the order that they are in the alphabet probably really isn't the best way to introduce them. But it is the way that is working best for these children this year.
I am, however, using similar resources found at My Montessori Journey (particularly from KidSoup) combined with ideas that were contained in the language album from the Montessori Online Training Course that I am taking - particularly the idea of Sound Boxes, although I keep all the items for the Sound Boxes on my newly named Letter Shelf. (What DID we do all day is taking the course too, so that is why some of our resources look similar.)
Here is my new Letter Shelf:
Cards that go with our Alphabet Song.
(on the first shelf) See next photo for more explanation.
(3rd sheet on the right on the blue shelf)
Alphabet flashcards that show the capital and lowercase letters together (on the 2nd shelf. The Flashcards came from the dollar section at Target last fall.)
The pictures in the Letter Cards are the same pictures that appear in the Little Letter Books.
So far, LOVING the new system. The children are really learning the letter sounds and they enjoy doing many of the activities.
