It was an interesting idea to have kids building with materials that felt similar to those in the architectural photos. But the rhyming text and illustrations felt like a mismatch to the strong informational photos. The poems were all arranged graphically to try to mimic the building materials, too. The assumption that rhyming text makes a good children's book is faulty and in this case distracting. In fact, I would have preferred photos of kids building with these materials over the illustrations.
