Khan's effort is praiseworthy. But we need improved math curriculum for each grade. We are sick of easy to do math curriculums. These are just waste of money; these curriculums don’t help our children to compete with the international students.
Our students are extremely good, smart, intelligent and competent. If they get proper guidance then they can rock the world. They can do better; accelerate innovation by having more challenging Math curriculum to match the exceptional level of intelligence; we need a math program that will increase the expectation of what our young generation can achieve. Recently I have found tutorteddy math curriculum. I have bought it for my daughter; she is in 8th grade. The curriculum is extremely good, cheap and reusable.
