Ms. O'Hara: RE your story Sunday, "Does proficiency give full picture?" >From your lede: *"Pop quiz: What number is both a prime number and a factor or 56"?*
If I understand correctly, this is a question on an exam given to fourth graders, 9- or 10-year-olds. Could you please point me to some source in the city or state education departments who can tell me what short- or long-term value this question about mathematics -- NOT arithmetic -- has for students that age? We live in a state where it is a rare cashier who can do the mental arithmetic to make change from a $20 bill. Can we first find out if fourth graders can do that before getting into primes and factorials? -- ============================================ Tom Johnson - t...@jtjohnson.com Institute for Analytic Journalism -- Santa Fe, NM USA 505.577.6482(c) 505.473.9646(h) *Visit Global Santa Fe <https://www.cloudhq-mkt29.us/mail_track/link/6145c0f66e61f84a31_1721673834933?uid=226430&url=https%3A%2F%2Fglobalsantafe.org%2F>* ============================================
