Also, worth noting that the sequence and content varies between states. North Carolina has Math 1, Math 2, Math 3 which replaces Algebra 1,Geometry, Algebra 2 with some topic re-ordering. Also, individual schools can implement gifted programs and curriculum differently (NC has a mandate for implementation of CCSS to specifically address the needs of AIG students.) The state suggests one way of doing this by using a 4:3 compacting; so, grades 6-8 cover the 6-9 material (or core 6th-8th and Math I.)
