I love the cheerful and always clear approaches that @howiehua.bsky.social shares. I'm going to show his www.youtube.com/watch?v=KAYg... to my algebra students in learning about harmonic mean. Lesson: understand the concept and the "why", then application will be clear. #mtbos #iteachmath #mathisfun
Is this a new way of finding the harmonic mean???

I have two students - and the younger 3rd grader brought a friend Chatter Max - in the midst of an assessment to possibly join @trianglemath.bsky.social for #mathisfun and language arts classes. I am optimistic about their placement though I wasn’t prepared to assess Chatter Max! #mtbos #iteachmath

Just a few minutes later I ran across this ball and it gave me an idea for future #mathwalks - is it big or small? What do these terms mean? In fact ‘Big Numbers’ is the topic of my Chapel Hill #marhcircle session for 1st-3rd graders tomorrow. #mtbos #iteachmath #mathiseverywhere #mathisfun

Before our last unit on fractions, I'm going to ask my level 3 students on Thursday a Purple Comet! Math Meet #mathCompetition #purpleCometMath purplecomet.org question that isn't bad if one carefully counts. I highly recommend color-if they use color, that will help! #mtbos #iteachmath #mathisfun

I'm thinking of asking prealgebra & algebra students this challenge question. AMC questions are generally tough, but some can be easy. I might change this to something sneaky like having 170 cans with the top row having two cans. #mtbos #iteachmath #mathisfun artofproblemsolving.com/wiki/index.p...

I love in-person & remote tutoring. Each week I work w/ a smart 1st grader (since he was a Kindergartener) remotely & just finished our 40m session. We talked last week about estimating; he claimed he could differentiate large numbers. We're leading to #mathisfun #fermiEstimating! #mtbos #iteachmath
