NYC public schools deceived me into thinking my son was a straight-A math student but he cant do fractions, basic algebra

For 13 years, Adriana Aviles, a fierce education advocate and former NYPD cop, has been the ultimate insider in New York City schools.As a powerful leader on the Citywide Council on High Schools, she championed Queens District 26 as one of the best in the city.

She knew the principals and the teachers — and trusted them.She was gratified that her son consistently received good grades, especially in math, throughout his K-8 years.

He couldn’t solve basic algebra.He couldn’t do geometry.

He couldn’t compute elementary-school fractions.Yet at PS 221Q, the North Hills Elementary School, he regularly received the highest grade in math.At MS 67Q Louis Pasteur Middle School in Little Neck, his lowest math grade on an end-of-term report card was an 89 in seventh grade.

He got a 92 in sixth grade and a 93 in eighth grade — the equivalent of As.When he was admitted to his first choice high school, one New York’s top-rated schools, we had every reason to believe he would continue to excel.What I saw when I sat down with my son to study shocked me to my core.He stared blankly at the page, completely puzzled by the material.He was completely thrown off by equations that conta...
