My mother-in-law brought this toy for my daughter and I love it for her. She's going to be 4 in a month and it's helping me teach her shapes. The moon shape is the only shape she had a real problem with putting together, but everything else she could do. We ended up playing memory with it by turning over the halves and picking at random. I like it because it's a fun toy for her while exposing her to shapes she wouldn't normally see. The extra appeal to her was that it was in the shape of cookies (something she's very familiar with). I love this toy and highly recommend it!
