Hi. OP here. On the Rational Number Project matter, you'll notice that I didn't recommend the entire body of work, but rather one article relevant to the matter at hand. It's worth a read—totally practical and applicable, and it reinforces Mr. Khan's intuitive sense that decomposing decimal numbers is important. I do look forward to future iterations of the decimals stuff. The teaching and learning of fractions and decimals is tremendously complicated stuff. Problems in this area are arguably at the root of many, many people's struggles in mathematics, which is why I think getting it right matters so very much.
