Hexagon- the first spark | DIY: Math PD
https://diymathpd.wordpress.com/2014/10/30/hexagon-the-first-spark
Sometimes it's better to just do it ourselves. Hexagon- the first spark. This was my warmup today:. Draw a six-sided shape. I followed up in our discussion with “Is a hexagon a 6-sided shape? 8221; and “Are all 6-sided shapes hexagons? 8221; Tomorrow they’re going to be in groups to categorize the shapes from Christopher Danielson’s Hierarchy of Hexagons. Project. These are my probably incoherent notes:. Lots of people said yes, so we had to look up the definition of a hexagon. 6th period: Much less deba...

Hallmark ain’t got nothin’ on us. | DIY: Math PD
https://diymathpd.wordpress.com/2014/04/16/hallmark-aint-got-nothin-on-us
Sometimes it's better to just do it ourselves. Hallmark ain’t got nothin’ on us. We did an awesome project today inspired by Fawn. Coming up on area of composite shapes, I needed a way for students to practice the composite-ness and the “splitting up” skill. A popular text book problem asks about pools and tiling/grass/etc around the pool in the yard, so I thought about having them draw a pool and do all that jazz, but I couldn’t really get that idea together. Foreshadowing of calculus: the smaller we sp...

NCTM14 -> New members? | DIY: Math PD
https://diymathpd.wordpress.com/2014/04/13/nctm14
Sometimes it's better to just do it ourselves. NCTM14 - New members? NCTM 2014 left me ON FIRE. (Almost literally, it was so hot walking around on Saturday.) But seriously, it left me hungry for more: more PrBL in my classroom, more student conversations, more teacher online collaboration, more ed conversations, more all of it. Give a “new teacher” discount” a la student discount (how do you define/prove “new teacher”)? Give a first-time attender discount? As well as a similar one for prospective teachers.

Hexagons, cont. | DIY: Math PD
https://diymathpd.wordpress.com/2014/11/03/hexagons-cont
Sometimes it's better to just do it ourselves. Friday, we dove into a modified version of Christopher Danielson’s hexagon activity as partially described in my previous post. Instead of coming up with classifications for each individual shape, I asked students to group the shapes. Not a lot for them to go on. Here’s what I saw…. These pieces fit like a puzzle. They’re long and skinny. They look the same. Just enough so that each hexagon is in one group. November 3, 2014. Hexagon- the first spark. You are...

Small Groups | DIY: Math PD
https://diymathpd.wordpress.com/2014/10/29/small-groups
Sometimes it's better to just do it ourselves. Was able to do small groups with proofs today. I let them self-select into my facilitated group while the rest of the class tried on their own and checked against answer key posted online. Identified where individual students had trouble. Automatic buy-in because of the self-select. Students who were working independently were excited to try the proofs on their own. Only got through 1 proof.

Math Coolisms: The Curse of Rote Teaching [PEMDAS & its Siblings]
http://mathcoolisms.blogspot.com/2013/06/the-curse-of-rote-learning-pemdas-its.html
Where Math Education matters most! Sunday, June 30, 2013. The Curse of Rote Teaching [PEMDAS and its Siblings]. An excellent question was raised in the Global Math Department. Bulletin board that I decided to elaborate upon in here. In this post, I will address an MB related to PEMDAS. So, what to make of a student's treatment of let's say 4-6(3 x. The same way as -2(3 x. So, have the students predict the nature of the graphs associated with the above two expressions and then have them execute the actual...
