Pamela loves this RDI exercise we do to help her reference my face for information. I have twenty-seven cards with one of three shapes (heart, triangle, circle) that are one of three different colors (red, yellow, blue) that are also one of three different sizes. I think of a criterion for each turn for her to match: same color, same shape, or same shape. I give her a card and think of a criterion (same color), and then she must point to a card. If it is the same color, I will smile; if not, I will frown. Once she finds a matching card, I shift my criteria and she has to find the next card by reading my face. She thinks my frowns are hilarious and giggles away. At the end of this clip, she even imitates my frowns! We both have much fun with this game!
