I few months ago I was given this set of pattern piggies and their sorting cards. I had tried a few times to use them with the boys, but they just weren't ready yet. However, I busted them out this week and both boys did great with them. The piggies are different colors and different sizes. There's the daddy pig, mama pig, brother pig, and the piglet. The pattern cards are either by size or by color. What I like about this set is that the boys have to pay attention to detail and follow specific directions to get them all done correctly. They really enjoyed playing with these.
