I first saw this activity while I was teaching at a Montessori school. I found it very helpful in teaching the kids how to visually recognize letters and also it helps them realize if the letters are right-side up or upside down.
While Little Angel was doing this work, she realized that she had placed the "a" upside down and fixed it herself.I have a free download available for the letter matching at www.montessoriforlearning.com (Letter Recognition Matching Cards)
