Task of the Week: Cobblestones

Task of the Week: Cobblestones

This week our Task of the Week is located in Estonia. In the city of Tartu the German mathematics teacher Sascha Abraham created the task “Cobblestones”. In the following he describes his task and the Erasmus project “Making Technology Meaningful Through Digital Pedagogy”, for which he developed this interesting task.

How you get to know the MathCityMap project?

In march I participated in a workshop of MathCityMap. Unfortunately, I didn´t have enough time last school year to work with MCM in math class, but I am going to use the app in this school year. I want to use the tool in two ways. Firstly, I create trails to repeat the educational content before an exam or to illustrate the mathematical content. Secondly, I want that older students create MathCityMap tasks for younger students.

Please describe your task. Why did you create it? How could it be solved?

I created a mathtail and this task within the frame of the Erasmus project “Making Technology Meaningful Through Digital Pedagogy” in order to present MathCityMap to other teachers. The Erasmus project works on the question, how “new technologies” (e.g. electronical devices like tables or smartphones and available software) could benefit mathematical education. In my opinion, MathCityMap enables students to experience mathematical problems in the “real world outside the class room”.

The task cobblestone is an example for a counting task (How many cobblestones are placed in this area?). The task can be solved by calculating how many squared cobblestones at the rectangular area. However, there are two planted areas, wherefore students have to subtract the missing cobblestones. Lastly the students have to add the number of cobblestones, which are placed around the benches. The aim of the task is that students learn to observe their environment carefully in order to solve mathematical problems.

Why do you use wizard tasks?

Wizard tasks are mathematical standard problems, which can be identified nearly anywhere. Through the usage of the MathCityMap wizard users can created a small set of tasks very rapidly. In addition, wizard tasks demonstrate new users different possibilities for interesting mathematical problems.
