These small sets of wooden blocks are great for children roughly 3 to 4. These are quite small sets and are intended for youngsters who are in the out-of-diapers, beginning day care stage. For these children larger sets are a waste of money as they won't employ more than 10-20 blocks at a time. (They will learn the names of shapes however).
At the extreme, the TOD Sets are big enough to get started building, though if your child is already playing with blocks and building houses, you might be better advised to consider our Beginner Sets in the next larger group.
