These have been so great to have on our fridge. My 4 and 6 year old have been putting them in alphabetical order, and also matching beginning sounds with animal magnets we have. My twin 2 yr olds love to move them around and ask what letter each is. They get so excited when they find letters for their name. The only down side is a few can be easily bent. The sign for Z has already been glued in one place. But I do have four children who are all very interested in them, so I guess it's a bit expected that they won't last. I think I would LOVE them even more if they were made of wood instead of thick foam.
