My 2 1/2 year old grandson can now read all the words on these cards. Other sets of Flash cards from this company have been used with him as well. I purchased these cards so I had a set to use with him, as his are at his home. He not only can count to 200, he knows his colours, shapes, animals. He is reading sentences put together from the words of all the sets. I am talking, printing the sentences on anything and he reads them.
