I have many of the instant learning centers and love them all. It makes center time fun, engaging, and reviews previously taught skills. The directions make the use of the center easy to understand.

I cut the mats in half so that I could sort the word based on their vowel sound when I wanted to. I don't think you can even tell they didn't come that way. The tiles are stackable and my kids like that feature when they use this set. They sometimes spell the first word, then stack the new letter on top of the first.
