It is a very engaging program for my 3 year old son. He already knew his letters and phonics but he enjoys the review, the songs, and the characters. The pronunciation of the letters in the songs seem a bit off; it sounds like the gal is saying "ba" instead of making just the "b" sound, "da" instead of the "d" sound,etc, so we work more on correct pronunciation. He struggles still with putting words together and I worry it's more about him memorizing the words and less about actually learning how to read. He's been able to read the first two books and with just the word review (without pictures) he struggles with some words. We practice diagraphs and sight words separately and so it helps him Underwriter how to put words together a bit better. Trying to write the letters is very challenging for my 3 year old. I have special toddler pencils and we practice traicing on sand paper letters with his finger prior to trying to write the letter or trace it with on paper. Overall, the program is at least very engaging and he's more than happy to do it every day.
