Gallery Walk

This class built off of our previous discussion of looking to find multiple solving methods for one problem. We began by watching a TEDTalk in which a math teacher gave examples of problems and the various ways in which her students conceptualized and understood them. She mainly discussed series and how students observed patterns of growth by connecting them to other ideas. For example, one student saw the terms of a geometric series that took the shape of a triangle to be a visual representation of sand being poured into a pile. As more sand was added to the height of the pile, more sand spilled over the edges and made the base wider.

I am a very mathematical thinker, so when I look at a series like the one above, I don't often think of it in an abstract way when it comes to explaining the changes. I immediately jump to the algebraic expression that is used express the series. It was very interesting for me to see into the minds of various students to understand the ways in which they perceive problems. Believe it or not, we don't always have to think so mathematically about things in a math class!

Following our class discussion of ways in which we interpret patterns in sequences and series, we worked in groups to create various methods of answering a question: "How many dots will there be in the 100th figure?" We worked to create graphical, visual, algebraic, and abstract solutions, all using different methods of thinking about the problem. These solutions were posted for the class to see and we were able to walk around to see how other groups solved the same question. Comments were made on the pages and we gave verbal feedback on the creative ideas that were presented.




Using a gallery walk like this in a classroom is a great way for students to showcase their work in a context where they can be provided with valuable peer and teacher feedback. They can also be exposed to new methods of solving by observing how their classmates found and answer to the same problem. Activities like this allow students to broaden their spectrum of thinking beyond what they already know and understand. In turn, this can help them to solve similar problems in the future by having many different approaches in which they can solve and check their work.

The Japanese Bansho Method

In class we were introduced to a type of activity for problem solving called the Japanese Bansho Method. Ottawa Bansho defines Bansho as "a method of teaching developed in Japan that focuses on teaching math through problem solving. It allows students to see connections and progressions of the thinking involved when developing strategies to solve a problem" (https://ottawabansho.wordpress.com/bansho-in-the-class/). At first glance, this method seemed the same as the gallery walk activity that we had used in a previous class. However, this method takes solutions one step further by having students group and categorize solutions based on level of difficulty. We began the activity by solving a problem about a class with a certain number of boys and girls in it. This appeared to be a fairly simple problem, however we were again challenged to create multiple solutions. Each different solution was written on a separate piece of paper and posted on the board. Once all of the solut...

Block 1

My first block was a great first experience teaching in a high school classroom. I had the opportunity to teach a Grade 10 Academic Math class and it was a true testament to my passion for teaching and a clear indicator that I was right where I have wanted to be. I got to finish up a unit on quadratics, teaching concepts such as completing the square, quadratic formula, and problem solving. This was definitely a tricky unit for my students, as each new concept in quadratics builds off of the previous one, and many students struggled to keep up with the pace. Overall the unit was well done, although it is safe to say that the students were very happy to be done with it when it was over (seeing as it was the last of 3 units on quadratics). During this unit I was able to use Desmos to make graphing and visually representing quadratic functions quick and easy for my students. I often used this technology during my lessons and I also allowed students to use it for exploration activities. Th...

Creating Effective Problem Solvers (Reflection on Webinars)

As discussed in Building Thinking Classrooms , many students in math classrooms are afraid of and unable to effectively answer problem-solving questions. When provided with a problem to solve, students wait for the teacher's instruction and guidance rather than working out the solution on their own. Many students today have math anxiety and are afraid to fail. Even when a grade is not being assigned to a problem, they aren't willing to take risks and make mistakes when it comes to solving a problem that they haven't seen before. This webinar raises the question: how can we as teachers create students who aren't afraid to problem solve? How do we build thinking classrooms? One of the ways to do this is by moving away from typical lecture-style lessons where the teacher writes down formulas and solutions on the board and the students simply copy them down. This allows students to "learn" material without actually understanding it or retaining knowledge of it. ...
