I had more energy with my first. On the walk to kindergarten, we would practice skip counting which she was not entirely fond of. She had memorized and internalized up to her 12s before first grade. This let us talk about groups of numbers and early division and fractions. By 2nd grade (with some problem scaffolding), she could add and subtract fractions. She never got bit by the math bug and liked boys better than calculus in high school. But she is very comfortable with basic numeracy, so I'll take it.
My favorite math memory was when in 7th grade, I thought I'd show some fancy algebra to prove that 0.999... is 1. I first asked her how it could be. A couple of seconds later, she said 1/9 is 0.111... so 9/9 is 0.999... and also 1. Waaaaay better than my method. Good job kiddo.
Another favorite 1st or 2nd grade: look at the thermometer outside. Can it get colder than zero? What does that mean? And her eyes grew big, "there are numbers below zero?!?!"
