I made a little game for the boys to play, kind of like bingo, only easier!
I cut a square, divided it into 9 little squares and drew animals in them. I made one for each boy, only two animals were different. Then I drew a larger card with all the pictures for the caller. We didn't shout bingo until the whole card was full which made it easier for Gavin to understand. He loved it! He's already asked to play it again, which we definitely will! Jared didn't get the game at all, or maybe he just didn't care, but he really enjoyed putting the buttons on and off the animals.
