Great scaling strategy Elps! And a lovely way to find a decimal equivalent for 5/8.

Intentional math discussions beat chaos every time. Don’t fish for random answers—highlight the strategies that actually build understanding.

Some may find #ranked-choiceVoting complicated but my 1st and 2nd graders at Stanford #mathCircle seem to understand it. They have created scenarios where the winner is nobody's 1st choice, somebody's last choice, determined by a "spoiler", and more. #mathisfun #mtbos #iteachmath #mathAndVoting

In this week's Stanford #mathCircle, we look at very nice work my 1st & 2nd graders have done w/ranked-choice voting, a "spoiler" choice, when we seek consensus, etal. I'll introduce idea of other kinds of majorities: absolute maj, supermaj, unanimity. #mtbos #iteachmath #mathAndElections #mathisfun

Rather than stressing why one doesn't belong, emphasize what the other three have in common. Discussion is key! Do it for each quadrant!
