Presentations & Workshops. Get Posts by E-mail. January 7th, 2015 by Dan Meyer. As I mentioned on Twitter earlier this week. I find a particular kind of math problem extremely exciting now. Here are five of them. I want to know what to call them. I want to know what are their essential features. I want more of them and I want to. Here is one of the five, taken from Scott Farrand’s presentation. Here are some points in the plane:. 4, 1), (17, 27), (1, -5), (8, 9), (13, 19), (-2, -11). These problems are a...

Explaining Huffman’s Impossible Pyramid | mathblag
https://mathblag.wordpress.com/2015/03/11/explaining-huffmans-impossible-pyramid
Musings on mathematics and teaching. Explaining Huffman’s Impossible Pyramid. I read about Huffman’s Pyramid from the consistently excellent blog Futility Closet. Huffman’s Pyramid is a drawing of a figure that cannot exist. However, the impossibility of this figure is hardly obvious. Here is the reason: if the slanting lines were extended, then they would have to meet at the apex of a pyramid. However, the lines do not meet. Contradiction! Are you convinced yet? To represent a polyhedron with two triang...

Tape Diagrams, Big Feelings and other Predicaments of Teaching – Discovery and Conjecture
https://discoveryandconjecture.wordpress.com/2016/11/19/tape-diagrams-big-feelings-and-other-predicaments-of-teaching
Tape Diagrams, Big Feelings and other Predicaments of Teaching. November 19, 2016. Many, many 4th graders I taught repeatedly told me, Tape diagrams don’t help me. Teachers wonder how much value they should assign to a child’s ability to make a tape diagram that accurately represents the problem. If a kid can solve the problem but can’t make a tape diagram that matches, what does that mean? A big, big question for me as a 2nd grade teacher is whether or not making tape diagrams is developmentally appropr...

Dots! | Talking Math with Your Kids
https://talkingmathwithkids.com/2014/06/30/dots
Talking Math with Your Kids. Reports from the field. June 30, 2014. The New York Times published an article about Common Core homework. As is going to be the case with a news article (in contrast to say, a post on a blog dedicated to children’s mathematical ideas), one can’t really learn any mathematics from the piece. One critique got hit twice, though that children are being forced to draw lots of dots. Here near the beginning of the piece:. And a bit later:. Talking Math with Your Kids. Arrays (with d...

Chinese School – Are Our Children Tough Enough | Mr Lock's Weblog
https://mrlock.wordpress.com/2015/08/04/chinese-school-are-our-children-tough-enough
Mr Lock’s Weblog. A blog about teaching – my job! August 4, 2015. Chinese School – Are Our Children Tough Enough. This blog was written in 55 minutes following the programme. Please forgive any errors. Prior to the first episode of Are Our Children Tough Enough. Broadcast on 4th August 2015, very many people (including many teachers) on twitter, and I’ve no doubt many not on twitter had decided to dismiss any possible positive outcomes. The most common response was a varient of. There were more predictab...

https://mikesmathpage.wordpress.com/2015/08/05/what-learning-math-sometimes-looks-like-counting-edition
Mike's Math Page. What learning math sometimes looks like – counting edition. Aug 5, 15. Ran across a nice example problem in Art of Problem Solving’s. Introduction to Counting and Probability. This morning – problem 5.5 in section 5.3:. In how many ways can a dog breeder separate his 10 puppies into a group of 4 and a group of 6 if he has to keep Biter and Nipper, to of the puppies, in separate groups? Next we looked at the approach using case by case counting – could we find the mistake here? What a ki...

An attempt to explain Graham’s number to kids | Mike's Math Page
https://mikesmathpage.wordpress.com/2014/04/12/an-attempt-to-explain-grahams-number-to-kids
Mike's Math Page. An attempt to explain Graham’s number to kids. Apr 12, 14. Last week Evelyn Lamb posted a great piece about Graham’s number:. Http:/ blogs.scientificamerican.com/roots-of-unity/2014/04/01/grahams-number-is-too-big/. I’d never head of Graham’s number before, but Lamb’s piece (and the Numberphile piece linked in the piece) really grabbed me. Here’s their video for completeness:. This is all pretty heavy stuff, so I wanted to come back a little bit closer to reality, so we wrapped up with ...

Mike's Math Page. Random thoughts since the start of the All-Star tour. Aug 12, 15. Qxhna Titcomb told me about her plans for the All-Star ultimate tour this winter. The only thing that wasn’t super exciting to hear was the August stop in Boston – we’d be on vacation😦 Below are some things that I’ve learned from the start of the tour from my chair on vacation:. 4) Though I would not thought it possible ahead of time, watching Opi Payne play in the Molly Brown All-Star game the filmed games from Colorado...
