As promised, here is our preschooler area. We have the little rocking chair, preschool sized pillows and as I like to call them - the Busy Bins. Each bin has a different activity and every so often I switch things up so the activities don't lose their staying power.
I have found the more activities I have for my preschoolers that involve fine motor skills, the easier time they have writing when they get to school age. The puzzles help with problem solving in math and the view finder and blocks help with coordination, imagination and problem solving as well. There is also a mini trampoline and jumprope out there as our current preschooler is a boy and physical activity is worth it's weight in gold during school time. Sometimes a boy just needs to move before he can settle. (Girls like jumping too!)
