Trig Summer Assignment

Summer Mathematics Prep Chesterfield County Public Schools Entering Trig/Analysis or Trig/Advanced Algebra Department of Mathematics

Summer Mathematics Prep documents provide self-directed student review, practice, and preparation for high school mathematics courses. Students are encouraged to first attempt these review problems on their own. Checking accuracy against the solution document can help students identify their own strengths and areas of challenge. Students can utilize instructional online resources to address areas of challenge. All of these resources can be found at http://mychesterfieldschools.com/about/instruction/other-academic-programs/summer-programs/.
