Math Wars

Math wars is the debate over modern mathematics education, textbooks and curricula in the US that was triggered by the publication in 1989 of the Principles and Standards for School Mathematics by the National Council of Teachers of Mathematics (NCTM). The term "math wars" was coined by commentators such as John A. Van de Walle and David Klein.

Examples of innovative curricula introduced in response to the 1989 NCTM standards include:

Mathland

Core-Plus Mathematics Project

Investigations in Numbers, Data, and Space
