My daughter figured out the letter A on her own because only the right pieces fit together, so she's not guessing. The wooden pieces feel sturdy and the upper and lower case letters paired with the little pictures make it easy for her to connect sounds to shapes.

The self-correcting design is genius, my daughter can tell she's got the right letter just by how the wooden pieces click together. She's been matching uppercase to lowercase on her own for twenty minutes without asking for help, which never happens.

My 4-year-old figured out the upper and lower case matching on her own within a day because only the correct pieces fit together. The wooden pieces have held up fine through daily use, no chipping yet.
