I got these letter blocks to help my son, who is dyslexic. I got them mainly for the different colours for vowels and consonants, and the fact they are like lego. I was not prepared for the size of blocks, boards or box. It was a pleasant surprise to find how tough they are and that the box will withstand the test of time.
My son is able to use the difference in colours when building a word, and implement the visual memory when it come to written words.
Also my 2 daughters use them to make word searches, hangman and to practice their spellings too.
I am very happy I found this product and that it caused for more than I expected.
