Our outdoor area is a work in progress, expected to be complete by September/October.
Our brand-new fence will be the home to the areas above. Our sensory table is custom-built from an old coffee table! We even have a mud bin! Everything was hand-done by my husband and I for their enjoyment. 
Our science area includes a weather station and plants. Our art has a whiteboard and custom-made chalkboard. P.E area includes multiple games for large-motor skill development.  There's also a yard to run around in, plus a dramatic play area.  
On nice days, we may just take snack outside, and we can also take our daily activity outdoors.
