Graph Builder is a sorting and counting game with Galah the friendly bird. A little jumble of things lands on a picnic mat: apples and bananas, hens and pigs, crabs and turtles. Tap one and it hops into its own column on Galah's clipboard, or drag it there. Every thing stacks up as a picture block, so your child builds a real picture graph. Then Galah asks with big picture buttons: Which has the most? How many ducks? The first stages have two kinds and a few of each. Later come three kinds, bar graphs with a number scale, ready-made graphs to read, and 'how many more?' questions. A wrong answer just wobbles, then the graph counts up with you. Each stage wins a new set of graph tiles.
