A Sociology teacher of mine liked to mention the lyrics of a song, when speaking about bias. He pointed out that people LEARN their values, and are TAUGHT their values.

"You've got to be taught
To hate and fear,
You've got to be taught
From year to year,
It's got to be drummed
In your dear little ear
You've got to be carefully taught.
You've got to be taught to be afraid
Of people whose eyes are oddly made,
And people whose skin is a diff'rent shade,
You've got to be carefully taught.
You've got to be taught before it's too late,
Before you are six or seven or eight,
To hate all the people your relatives hate,
You've got to be carefully taught!"
===================================
For high school, I went to the Bronx HS of Science. I found that a good place to address racism. When everyone in your class is above-average, and you have a variety of ethnicities represented in every classroom, the idea of some "race" being better or worse is easy to discard.
BTW, it's not that Asians are automatically better at math, it's that many are "carefully taught" to push for higher and perfect grades in math and hard sciences, so that a kid making a normal mistake may freak out about it because the family's pushed for a perfect score.
So, when you're shoulder-to-shoulder with a roomful of skllled people, their skin color can quickly become the least valuable piece of information.
