nitpick: this blog post was written in 2013, so they were wasting their time watching TV or browsing facebook, not on "twerk tick" (I assume you sarcastically meant tiktok)
major point that is not a nitpick but is related: Since 2013, especially since the pandemic, most educators I've talked to agree it's gotten significantly worse. It was bad then and it's awful now. The reality is if you can add, subtract, multiply, divide, estimate, convert between, and understand the real world meaning of fractions, decimals, and percents, let alone apply it to real world situations like which bag of flour has a cheaper unit price, you are in a minority of american adults.
