In this story YOU are going to be the whale. All at once he saw two fish swimming near him in the ocean. Show me what happened. Each child takes two fish out of the cup and places them on the ocean storyboard. Each child eats one of the fish.
Children answer one.
Pretty soon 2 more fish came swimming along. Show me with your counters. Continue the story having children add and subtract fish until all crackers are gone. This game should be played over and over again to reinforce number concepts at different levels. Let the children improvise on the theme and take turns telling the story to the group.
