“We can all be math people,” according to this encouraging debut. Sharma—founder of Zearn, a nonprofit organization that creates educational software—argues that contemporary math instruction places too much emphasis on speed and memorizing formulas rather than understanding the underlying concepts. Expounding on more effective ways to teach math to elementary and middle schoolers, Sharma recommends using “pictures and objects” to illustrate concepts and describes how one Zearn program shows video of a teacher cutting two oranges into quarters to visualize how fractions can represent sums greater than one. Sharma calls for institutional change, urging schools to commit more resources to assist struggling students instead of funneling them into remedial tracks. She also entreats parents to find organic opportunities to develop their child’s math skills outside the classroom (helping a kid determine “how long it will take him to save enough money to pay for a new toy,” for instance). Assertions that technology can “democratize access to an excellent education” come across as plugs for Sharma’s nonprofit, but the recommendations otherwise provide pragmatic ideas about demystifying math. It adds up to a sensible reassessment of how to improve math education. (Aug.)
