“About 1 in 5 adults in the U.S. lacks the math competence expected of a middle-schooler, meaning they have trouble with those ordinary tasks [calculating a tip, doing fractions to double a recipe, know how much change to expect from a cashier] and aren’t qualified for many of today’s jobs.”
I came across this quote in an article called “Early Number Sense Plays a Role in Later Math Skills“. The author attempts to trace this statistic back to a root cause and comes up with a University of Missouri study done with 7th graders who were given a test to assess a variety of math skills needed to function in the world as an adult. They found that the students who were behind on the seventh-grade test were the same students who had the least number sense or fluency in mathematics in the first grade.
“So I’m there on the beach with my friend Ben when we notice a taco cart up the road. Ben wants to walk straight over, but I’m thinking we walk a lot slower in the sand than we do on the street. So I say we walk straight to the street and then down the street to the cart. So we went our separate ways…” Thus begins the first Three-Act math task I ever experienced, courtesy of Dan Meyer.
