Colors (Red & White)

I guess a month or so ago we started exposing Nolan to some learning videos. After watching the videos, I made him some colors and shapes flashcards. Then we started having a few sessions a day of exposure to the flashcards. 

After that, I kept a record sheet of how often he chose right/wrong. It took about 3 weeks before I'd say he 'mastered' these two colors (meaning he chose correctly during every session for a week). He now mostly always choses correctly between red and white. Fixing to add in another color and start our square and circle card!
