Here's my 3 sentence blog post:

1) Word problems do not exist in real life outside of school.

2) We teach students strategies for solving word problems like Three reads and CUBES.

3) Students will never use strategies like Three reads or CUBES in real life outside of school.

I think this is a good article from @FiveThirtyEight about how they treat probabilities. A good read for any senior class.

Last week I was in San Diego for NCTM and while there I got around the city riding these electric scooters that were literally sprinkled all over the city. Well @MrOrr_Geek and @mathletepearce made a little mini 3 act task dealing with them

A couple of new ones from @MonaChalabi on the effect of skin colour on school suspensions

Do you know what colorism is? It’s the kitchen staff who are darker than the people out front waiting tables. It’s my family members hoping their kids will be light-skinned. And it’s here, in the US school system. Using data from The National Longitudinal Survey of Youth, US sociologists found a clear correlation between how dark a student’s skin is and the probability that they would be suspended. I found this part of the study important: “The disadvantage for darker-skinned young men derives from their link to a disfavored group (criminals) in an analogous way that the disadvantage for young women does (unfeminine and unattractive).” The researchers note that there’s a lot of discretion when it comes to how the school system punishes small offenses (like talking loudly) and darker skinned pupils suffer disproportionately. They note that future research should look at Hispanic communities too (I would add all poc communities to that list!) Source: Lance Hannon et al, Race and Social Problems, 2013 The Guardian has a special series all this week on colorism edited by Dream McClinton that I highly recommend!

Colorism affects how much money you earn... Economics professors studied the wages of men aged 19–65 who were working, not self-employed, and earning less than $100k per year. They found that those with lighter skin earned more. Source: Arthur H. Goldsmith et al, The Journal of Human Resources 42(4), 2007
