Most states (44 out of 50) in the US have signed onto the Common Core Curriculum this year including my state. Instead of having Pre-Algebra, Algebra I, Geometry etc. in the public schools, it will be Math 7, Math 8, Secondary Math 1, Secondary Math 2, and Secondary Math 3. They will be integrated with Algebra, Geometry, and Data/Probability spread throughout all the courses. Students will finish this series in 11th grade with the option to take Pre-Calculus in 12th grade. There will be an honors sequence which will cover the Pre-calculus topics allowing the honors students to take Calculus in 12th grade. It lines up pretty closely to the Singapore NEM curriculum I think. I know that our local school district will be starting the transition next year.
