Review on Revolutionize Learning with PicassoTiles Building Educational Construction Development by Jesse Stewart

Unfortunately they are very different from other Picasso tiles. They're not very modular. My kids had a hard time building tracks because the track and vehicle sizes are so incompatible. I was trying to build the track pictured on the box for my 5 year old son. In fact, it was impossible to build it like in the photo. As close as I could get to the picture, it actually didn't leave enough room for the cars provided to drive under the track. He and I were very disappointed that we couldn't even build the track shown in the photo. He liked building paths, but they had to be simple or non-circular or the path wouldn't properly cross. We LOVE other Picasso tiles but this was an expensive disappointment.
