Gia loves her set of letters and pictures. Her Melissa and Doug Self-Correcting Alphabet Letter puzzle really helps practice. She is able to play by herself as only one match fits; however, I like to get involved to provide some guided learning as well. For example, I will ask her to find the animal that matches the letter and then the letter that matches the animal. We also put them in alphabetical order to reinforce her alphabet practice. At the end, she has some fun of her own by building shapes! The puzzle pairs are made very well and come in a box with an easy to slide-in lid. I was so pleased that I got the number puzzle pairs too. We really enjoy the quality and fun of Melissa & Doug toys!
