Today, Arin and I were going to play Uno, however, Ella wanted to play as well, so we attempted to make it a little more toddler friendly. First, I set the game up by placing four cards on the floor (one of each color). Then, the girls took turns drawing a card and placing on the appropriate pile.
For Ella, that meant simply matching colors.
Once Arin was tired of playing, I laid four cards on the floor, one of each color. Then, one at a time, I handed them to Ella and she would match their colors. Without so many options, she was able to match the colors pretty easily.
