Banking for a practical number sense

Students in sole proprietorships or partnerships keep the banker busy as they earn base-ten units with each roll of their dice. By placing their groups of ten on the correct columns of their company’s place-value mat, they trade units for longs, and longs for flats as their mats fill with earnings. Student entrepreneurs who maintain orderly transactions should be able to tell the banker what the value of their business is whenever prompted. This gently competitive exercise helps students learn and improve their knowledge and understanding of  place value.
