Review excerpt: This sixth App from Duck Duck Moose is designed for iPhone and iPod Touch and contains seven easy to explore games, each with multiple ways to explore some powerful math concepts — of the variety that will someday loom at the root of an SAT question. The games include Swing (Count up to 50 as a rabbit swings. You can either watch, or “push” the rabbit with your fingertip); Slide (Help ducks climb to the top of a slide. Quantities are show both visually and in an equation, simultaneously); Seesaw (Balance a seesaw by adding and subtracting mice); Apple Tree (Subtract as apples fall from a tree); Sandbox (Complete patterns by dragging and dropping toys); Bench (put dogs and numerals in order, from smaller to larger. It’s especially nice that you can make the order from either left to right or right to left); and Picnic: Counting (Feed a hippo the correct number of food items).
