How is it possible to count a complicated pattern of strawberry seeds or grapes on a vine or camel humps–in a blink of an eye? If children can open their minds to new ways of perceiving math, anything is possible! Greg Tang shows readers creative ways to use patterns and combinations of numbers to solve math puzzles quickly and effectively. Rather than laboriously counting 24 mushroom slices on a pizza, Tang suggests: "Let me give you some advice, / Just do half and count twice." And in adding the number of dots on a fan: "Instead of seeing groups of threes, / Count by fives and it's a breeze!"
