These small sets of wooden blocks are great for children roughly 3 to 4. For these children larger sets are a waste of money as they won't employ more than 50 blocks at a time. (They will learn the names of shapes however). We can't stress too much that the way to buy blocks is to start small and expand the set over three of four years, enlisting relatives, marking birthdays and holidays. A 3-4 year old needs to be encouraged to play with blocks by playing with them - and more than once.
