This simple memory game I started with Eaton about 3 months ago when he was 22 months old. I wasn't so consistent with doing it because it was hard for me to find a right time when Eaton was willing to do that activity. I did that only one a day.
I will try to introduce that game again with increased number of cards.
I will use one of my favorite site for free printables.
I use these cards because they teach plural and singular words. Great activity:2 in 1!
