Math

Third graders learn to take measures into their own hands and bring King Peter Plus, Queen Mary Minus, and Martha Multiplier, and Duke Divide into the practical world. Topics of exploration include linear distances, through the use of rulers and measuring tapes, mass, by way of scale balances, volume, through simple kitchen accessories such as teaspoons and cups, and time, from the seconds, minutes, and hours of clockwork to the days, weeks, months, years, millenia of calendarwork. Third graders also practice the art of bartering by calculating change to make-believe purchases. Regrouping (borrowing), multi-digit multipliers, and long-division are practised throughout these exercises.
