The chunky wooden pieces are easy for little hands to grip, and my daughter loves that each pair only fits one way, so she can check her own work without me hovering. We've been doing a few letters every night before bed and she's already matching upper and lowercase on her own.

The self-correcting design is genius, my daughter can tell right away when a letter piece doesn't fit the right picture. We've been using them at the kitchen table for about 20 minutes a day and she's already matching upper and lower case on her own.

My four-year-old is obsessed with these, and I love that each letter has its own object to match, like an apple for A. The upper and lowercase on the same piece is such a smart touch since we're working on both right now. He'll sit and do the whole alphabet without me even asking.
