DS8 is also in 2nd grade. He is pretty much self taught. He wanted more in math , so we started going through singapore math. He completed through 4b as a first grader. His spring MAp score was a 235. His school starts compacting math in 3rd grade (its 3 years of math completed in 2 years). DD10 is in this program (finishing 5th grade math as a 4th grader) and her MAP score finally surpassed DS this spring due to exposure.
