I got out the old Dora TV telephone video game for my 3 year old:
Amazon product
and let him play with it this morning. We heard him asking, "where's the 2? I can't get the two!"
So I helped him learn how to do the controls. He was apparently playing a math game where dora would give him "1 + __ = 3" and he was looking for the two to complete the equation. I figured the video game waited for a bit, then told him the right answer, so I didn't think much of it, but I stuck around after showing him how to select the two.
The next questions was "5 + __ = 9" and he stared at it for a few seconds, then started saying, "Where's the four... wheress the four..." and he was able to find the four and select it. Apparently Dora did not become impatient and tell him the right answer - not only does he know his numbers, but he can do simple addition.
Obviously our plan of completely ignoring him and letting him decide how much to watch educational shows and how much to play outside is working. Thank goodness for Roku and Netflix.
