Students in a similar class made these Riemann sum puzzles:

Here is some data on this. (darker dot = higher pass rate on 4th grade math state test; 21 = proposed avg class size cap) You are correct that there are many schools with large classes and excellent outcomes. Schools with good test results are popular and become overcrowded.

One more... What do you #noticeandwonder ?

Which schools benefit most from the proposal to lower class size caps in NYC? A snapshot of elementary schools in 4 NYC districts: * 21 = proposed avg. cap for elem. classes * darker dot = higher pass rate on state test (4th grade math) * left to right = decreasing affluence

Or know about, and have access to, the "STEM Pathway" of extracurricular and advanced math/science experiences: beammath.org/the-pathway

A mini-story, translated from Contes liquides, Jaime Montestrela and Hervé Le Tellier A #math question: How long would it take to "count" to 80,000,007,002, in alphabetical order?

However: Only <<10% of Harvard freshman did not take calculus in high school. >25% took courses BEYOND calculus. features.thecrimson.com/2019…

And I’m concerned about how some kids have access to a “STEM pathway” of advanced and extracurricular math work, while other families don’t even know it exists. So messaging that ignores or downplays this is problematic. (beammath.org/the-pathway)
