Here is a presentation on it.
http://www.pisd.edu/staff/districtdigest/2009-10/Math_Rocks.pdfIt is a 2+ year acceleration for mathy kids. Kids also get a lot of college credit.
Here is the class sequence.
6th grade: Honors Math Rocks 6.
7th grade: Honors Math Rocks 7 with Honors Algebra 1 (for high school credit).
8th grade: Honors Math Rocks 8 with Geometry (for high school credit).
9th grade: Algebra 2 combined with Pre-Calculus (for 2 high school credits).
10th grade: Calculus 1/Calculus 2 (for college credit from UTD).
11th grade: Differential Equations/Number Theory (for college credit from UTD).
12th grade: Abstract Algebra/Multi-variable Calculus (for college credit from UTD).
A lot of kids also take the AMC series. ( A high score on the AMC is much better than a high score on the SAT.)
