#1 Pipe Cleaners and Colander
What a huge success! He did this for 30 minutes straight. It took him a little bit to figure out how to actually get them in the holes, but filling up the strainer was just as fun.
#2 fabric balls and cupcake pan
This one he liked to, just not as much as the first. He "counted" as he placed each ball. We practiced numbers and colors. This kept him occupied for about 20 minutes.
#3 Play Doh
He actually liked playing with the cups more than the play doh. Every time he would touch the play doh he'd look at me with this "ew" face. I bought a set that had a truck which is a favorite of his right now so this was a solid 30 min plus of play.
Big. Fat. Fail. I saw this using fruit loops instead of beads as well, but he isn't quite there yet. I ended up just stringing the beads myself and them letting him take them off and put them away. This only gave me maybe 10 minutes.
