School Mathematics, followed by the Professional Standards for Teaching Mathematics (1991) and the Assessment Standards for School Mathematics (1995). Education officials lauded these math standards, and the National Science Foundation funded several projects to develop curricula consistent with recommendations of the standards. The Department of Education cited several of these programs as "exemplary". However, implementation of the reform has run into strong criticism and opposition, including parental revolts and the creation of antireform organizations such as Mathematically Correct and HOLD. These organizations object especially to reform curricula that greatly decrease attention to the practice and memorization of basic skills and facts. Critics of the reform include a contingent of vocal mathematicians, and some other mathematicians have expressed at least some serious criticism of the reformers in the past. In 2000, NCTM released the updated Principles and Standards for School Mathematics. Principles and Standards is widely considered to be a more balanced and less controversial vision of reform than its predecessor. Post–World War II plan In 1944, NCTM created a postwar plan to help World War II have a lasting effect on math education. Grades 1-6 were considered crucial years to build the foundations of math concepts with the main focus on algebra. In the war years, algebra had one understood purpose: to help the military and industries with the war effort. Math educators hoped to help their students see the need for algebra in the life of an everyday citizen. The report outlined three strategies that helped math educators emphasize the everyday usage of algebra. First, teachers focused on the meanings behind concepts. Before, teachers were expected to use either the Drill or the Meaning Theory. Now, teachers gave students purpose behind every concept while providing an ample number of problems. Second, teachers abandoned the informal technique of teaching. This technique was popular during the 1930s and continued during the war, and in essence depended on what the students wanted to learn, based on their interests and needs. Instead, math teachers approached the material in an organized manner. The thinking was that Math itself had a very distinct organization that could not be compromised simply because the student was uninterested in the matter. Third, teachers learned to adapt to the students by offering the proper practice students needed in order to be successful. After the sixth year, seventh and eighth grades were considered key in ensuring students learned concepts, and
