Are you taking Algebra I, Geometry, or Algebra II in the fall?  Do you want to brush up on your Algebra skills? Algebra Combat is back by popular demand! Algebra Combat is a one-week preparatory session run by Rivers School teachers, Samantha Vandergrift and Tori Wilbur. We will reinforce computational and algebraic skills as well as strengthen critical thinking and problem-solving skills. Target topics include real number operations, factoring, solving multi-step equations, graphing relationships, and solving systems. Students will start each day with a pretest to examine their existing skill set and this will determine their grouping for the day. The small classes along with the two professionals leading the groups will allow for individualized instruction and hands-on activities.  

Tuition:  $480.00

All materials and lunch will be provided.
