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

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

I'm preparing for Stanford 1st/2nd grade #mathCircle on math of #voting. Several years ago I shared tinyurl.com/mathInstVoting and now I'm adding material about midterm #elections. Most of the unit is based on concepts like majority, ranked choice voting, runoffs, etc. #mtbos #iteachmath #mathisfun

We're in a unit on analyzing games in 1st/2nd grade Stanford #mathCircle. Last week students wrote about games they like & why - what a nice list they compiled. So many correctly figured best/worst cases for guessing a number 1-100 with higher/lower feedback! #mtbos #iteachmath #mathisfun

Yesterday at @ncbg.bsky.social I had #mathisfun w/a gifted Kindergartner. In this our most recent session, we explored stochastic patterns & learned #PascalsTriangle. He was particularly engaged when I asked him to build Pascal's Triangle fr Legos(tm) at the end - to be continued! #mtbos #iteachmath

What a cute response I got to a #mathCircle question for 1st & 2nd graders re: number bases; we use base 10 because we have 10 fingers so have 10 digits. What if we had another number of fingers? This 1st grader had an answer for 11; for 16: "I would ask my daddy"! #mtbos #iteachmath #mathisfun

In ChapelHill #mathCircle my kiddo led a group w/her #origami love. I worked w/my 1st-3rd graders on #FermiEstimating. Several est. bricks on a walkway, leaves on shrubs, people at a white coat ceremony,etal. I disproved one who said they go to 1000 homes at #Halloween. #mtbos #iteachmath #mathisfun

I had a lot of #mathisfun with one of my 5yo students. We looked at counting including when items were missing, patterns including one where we included and discussed randomness, and partitioning. She brought a cool Lego(tm) structure and we discussed symmetry. #mtbos #iteachmath

In Stanford #mathCircle for 1st/2nd grade this wk we reviewed hw incl finding "Handshake Numbers" which some saw as Triangle Numbers. I love how some enacted this. One made a cartoon showing she understands-why with, say, 20 people, there are 19+18+17+...+ 0 handshakes. #mtbos #iteachmath #mathisfun
