The goal of universal early algebra is to get more students to take calculus in high school. Minnesota has tried it for years — with less-than-promising results.

Topics include systems of linear equations, matrix algebra, elementary matrices, and computational issues. Other areas of the course focus on the real n-space, vector spaces and subspaces, basis and ...

James Keivom Despite a citywide decline on the Algebra 1 Regents exams this year, the DOE mandated the use of Illustrative Math in all but six of 420 high schools. In a statement Saturday ...
