motivating and suitable

Recommended by a friend, his books st TB. I am learning to read to my son to read the first alone motivates him, he read it twice the first day of its receipt. he still has 2 sounds pr able to read the second, he looks forward.
I find that these six progressive works are great and very suitable ... damage than there is no other, I would have gladly bought several.
at that price no need to deprive rather deprive our children of this extra motivation pr learn to read.
