Over the summer I found a little trampoline at Goodwill for $5. I have been wanting one for a while to keep indoors for those long winter months of limited physical activity. In the last week or so, it's been hard to get outside and my kids discovered the trampoline. My 4 year old son likes to jump while shouting out is ABC's. The older girls shout out the Greek alphabet. They are trying to invent games that involve bouncing on the trampoline (kind of like an obstacle course in our basement).
