This summer I've been having DS do a workbook that helps him with reading comprehension.
Typically, there's a story (in this case non-fiction) and a set of questions (a,b,c,d choice) and one "essay" question.
Today the subject was Presidents' Day. The essay question was: "Do you think it's fair that Washington and Lincoln are the only presidents who have a holiday? Explain.
DS wrote: NO! 2P/43P is 0.8% of the presidents have holidays...that is NOT fair.
Originally, he wrote that there were 130 presidents (but oddly, his original percentage was correct for the correct-ish answer of 43/44!) We went online and I showed him that actually there have been 43 individuals who have held that office, even though there have been 44 terms.
I was proud that he used his math knowledge to support his answer.
