Challenging Minds: Enhancing mathematical learning of African American students through games

Presented by Dr. Crystal Hill Morton.

Minority Access to Revolutionary Instructional Extensions (MATRIX) was a two part pilot project that coupled parent engagement and supplemental mathematics instruction. The MATRIX supplemental mathematics curriculum was built around six games designed to foster the mathematical development of elementary students. This presentation describes the MATRIX mathematics curriculum and provides findings related to the project’s impact on African American students’ number sense and attitudes towards mathematics.

Great Articles!

This week's articles are split between a pair of articles shared by Audrey MacLaren about mathematics in the world around us and a reflection by Jenise Sexton on research in mathematics education shared by NPR.
Math in the Real World

I couldn’t decide which of these two articles to write about this week, so what the heck, here they both are. 

The first one’s about snow. In Montreal, as in many places around the US this winter, the big news lately is the snow, so this post by Marcus Woo about the math behind removing it all seemed apropos. Talk about real world math! If I were teaching graph theory, I’d have my students read it. It describes how one mathematician, Peh Ng, used the Chinese postman problem algorithm to find the most efficient snowplowing route in her own town, then gave it to the city planners, who then used it to save the city money!

The second one is about Bayes’ Theorem. I’m sure I learned it back in university, but probably only at the level of remembering the formula and recognizing when to use it – my least favourite way of knowing. This article uses Lego pieces to get it across. I love this kind of writing, and this kind of approach to understanding math – intuitive, visual, and infused with a love of causing understanding.

The Sigh Heard Around Twitter

Many of you have probably seen a retweet with the title 5 Lessons Education Taught Us in 2014.  

For some, the initial reaction was probably one of excitement.  You’re most comfortable when you can stand and deliver, tell students steps for completing computation, and drill students using timed tests.  Some of you may have vomited a little in your mouths, picturing those figure heads within your district saying, “See I knew this ‘new math’ isn’t what will increase our scores”.  And others saw through the selective data, stared truth in the face and carried on.

Looking closer at the actual data report it can be concluded the data used in the study was self-reported by teachers.  Therefore we have no information about the teachers’ understanding of mathematics, the manner in which these practices mentioned in the report were implemented, and no information about the teachers’ understanding of effective practice as defined by other research.

Puzzle for the week:

Look at the map below. If you are trying to get to Bronx Latin School in the Bronx, which subway stop (marked with an M) should you stop at so as to minimize your travel time to the school?

You can tweet @davidwees with your solutions or any solutions your students develop.
