Schönes Beispiel von Tim Brezinski zur Veranschaulichung des Zusammenhangs zwischen Durchmesser und Kreisumfang.
Gut geeignet für die Methode #thinkingclassroom im #Mathe #Unterricht in der #Schule

Mein #wowdw waren die erste Versuche mit der Methode des #ThinkingClassroom #denkendesKlassenzimmer im #Mathematik #Unterricht
Die SuS stehen in kleinen Zufallsgruppen an Whiteboards und lösen Probleme.
Viel Kommunikation, viel Diskussion, eine spannende Atmosphäre und eine willkommene Abwechslung.
Das Ganze macht Lust auf mehr. Sogar die SuS fragten am Ende, ob wir das nicht häufiger machen könnten…

Needed an extra lesson on lines in #Algebra2 since one class met an extra period this week for some unknown reason. Bouncing ping pong balls to the rescue! Students dropped ping pong balls from different heights and measured the rebound height, plotted the data and found a linear model. We haven't learned about regressions yet (soon though!) so they used a ruler to eyeball the best line.
Challenge time. I took all the balls away and told them to use their model to calculate the proper drop height for the ball to rebound to 78 cm. I rigged up a small hoop I had lying around at just that height so everyone in the class could tell whether the rebound was to the right height. Hilarity ensued when several groups realized their drop height predictions were below the rebound height. Turns out they plugged in for x when they should have plugged in for y. A good learning moment.
It was a pretty basic, last minute lesson, but I think it went ok. It was nice having everyone's data, graph, and model on the whiteboards around the room for all to see. I have whiteboards on all 4 walls (no windows though!).
