"Frank Corbo, the head of Staples' math department, said the district spent about $70,000 to develop the new math curriculum - half to pay two dozen teachers to work on it over the summer, and the other half to pay HeyMath!, whose Web server in Singapore gives students 24-hour, 7-day-a-week access to class lessons, tutorials and homework assignments. He said that the district will soon save at least $25,000 a year on textbooks."
