Dynamic & Modifiable Illustrator (w/o words) Not sure why many texts make this into such "thing" (by calling it a corollary or another theorem). Isn't the original theorem good enough?🤔 https://t.co/9L3SvzdyLS

Today we tried & ’s skeeball problem. They ❤️‘d it. I ❤️’d the variety of ways they organized their thinking 🤔 They know they can find more ways & R going 2 work on it at home 💕🌟

Ts: For those Ss who need a little more of a challenge 🙂: Given the base of this solid = circle of radius R, & cross sections shown here are regular hexagons, express the VOL of this solid WRT R. https://t.co/wptjdzXTxG

How will you approach your mathematicians Monday? Thank you & ❤️💡🎾 I loved the story, Infinity & Me. I’m going to try this in 2nd. I changed the numbers, and I’m going to ask them to reflect too.

Create your own solid: Cross sections || yAxis = regular hexagons. Upper & lower FNS & boundaries all modifiable . Explore here: https://t.co/wptjdzXTxG. Made w/ GC (now w/#AugmentedReality 😀!)

Sometimes it’s nice to think about how patterns grow, where they grow from, and if through their changes they might come to a limit.

Basic point plotting (x, y, z) & solid construction exercise in GC : Solids have = radii & height = 2*radius. And with Ss can VIRTUALLY TEST the accuracy of their models! 🙂 beta demo .
