I'm not sure about you but in Ontario right now we are having some very, dare I even say summer like days. I'll take them! This is actually an activity that we did in June but works great for warm fall days as well and is so easy to set up. I got the print out from Pinterest! (Thanks Pinterest) then just stapled them on some paper bags this set upbecame part of the activity for my older children, they love helping with play prep in the summer.
Finding items like robins eggs and animals that had passed, led to all sorts of questions and hand holding so that little fingers didn't get to close. It also gave me the opturnity to listen. The children were very empathetic to the animals and each other's feeling.
