Mathematical reasoning is every child's natural right. It is a capacity every human brain inherits, the product of countless generations of evolution. A capacity that took that long to develop deserves instruction attuned to it, not against it. Yet students are rarely given the foundation that reasoning could stand on: a named, ordered sequence that works on any problem, in any topic, and that every later skill can be built upon. 6QRC™ exists as a response to the nationwide decline in math scores by providing that foundation. It is built to raise the floor without lowering the ceiling: gifted minds will always see further, but now everyone can reach the starting point.
