These are sweet potato latkes I made for the last day of Chanukah.
9 yo pragmatically responded: "You did not live long enough to have a million meals."
This is the math that 9 yo did to show how many meals 7 yo ate in his lifetime. I helped him set up the equation, but he worked out the rest on his own.
This is my baby who thoroughly enjoyed the above-mentioned latkes.
This is why I keep on coming back to child-led learning as the best way to learn. This is why I doubt that there is a school program out there that would be perfect for 9 yo.
