Summary

The recently released New York math briefs (found here) are not scientific and describe questionable practices. Many of these practices have been shown through decades of rigorous research to be ineffective, especially for students struggling with mathematics. These briefs should be withdrawn.

This letter (read below) outlines serious concerns regarding grave omissions and inaccuracies in the New York math briefs in summarizing what’s purported to be evidence-based math instruction. Given the detrimental impact on New York’s youth, we are calling for a retraction of the New York math briefs. We request that they be replaced with materials that are accurate and based on evidence from rigorous empirical studies. Given recent national attention to student literacy, we are concerned that the briefs inexplicably reinforce several of the exact myths dispelled in the Science of Reading. The result will predictably be that New York's poor math performance will not improve.
