This was an easy (and fun) activity that we all enjoyed. We have played with golf tees in the past, and had SO much fun (check it out!). My Little Guy will often times ask if I can pull out the golf tees for him to hammer into an empty egg carton.
We took this activity outside and hammered away! This was big time fun for Little Guy and Big Sister. They sat for a long time as we hammered golf tees all around the big tree in our back yard.
Baby Girl got in there, too. She would pull the tees out and put them back into the holes.
We ended up adding the yarn again to connect the tees for more fine motor (and fun) play.
