After writing about how Caspar was using Montessori number work to practice his numbers, I received a copy of Montessori letter work to review also. Having these books together is really useful. You can see our letter work book is looking worn, it's certainly getting used.
I would suggest these books are best suited for a child around three years - when the child first expresses an intersest in writing. Although Otis at 20 months loves counting books and Caspar at five years uses these for practicing some of the more difficult numbers and letters.
The books could be used alone, in conjunction with a sand tray, chalk and black board or pencil and paper. The books are board books, thick and sturdy. The numbers and letters are slightly textured, not as rough as the sandpaper letters I've felt.
I've said it before but I think these books are a great at home alternative to the sandpaper numbers and letters. They would also be a good home schooling tool and could be combined with other methods of education.
Caspar was first introduced to the sandpaper letters in a Montessori school environment. At home he sometimes traces the letters with one finger, sometimes two and sometimes he just brushes his hand over it. He is left handed though.
