We used Peter's Lego Duplo Read and Build set for play school time yesterday. This contains a book and the bricks to make two Lego models that are part of the story. He asked for the book ten times in a row (no joke!). I really like this set as it is a first introduction to the world of making models using Lego instructions and anything that encourages a love of Lego is a winner in my opinion. It's great for motor skills, colour recognition, problem solving, creative play and we have (so far) used it to learn about height and as manipulative for adding and subtracting!
