    Although linear algebra has been included in the high school curriculum (CCSSI 2010), better support is needed for teachers. Most textbooks are written for college students and emphasize heavy computations, algorithms, and procedures.

The school administration scrambled to find a replacement, going from substitute teachers to mathematics graduate students (from a nearby university) to its own mathematics chair, who had no previous experience teaching linear algebra either.
