Educators at a small private Christian school in Olde Town Augusta are seeing results with a math curriculum imported from halfway around the world.
For the past three years, Heritage Academy has used Singapore Math as its basal math curriculum for kindergarten through sixth grade.
In the first year the school adopted Singapore Math, all of its kindergarten and first-grade pupils met or exceeded proficiency standards on the Iowa Tests of Basic Skills, as did 80 percent of second-graders.
Why use math from Singapore?
