Task of the week: Rainbow garland
Today we would like to present you the task “Rainbow Garland” as the task of the week, which was developed and published in Berlin by math teacher Felix Schlosser. The goal of the task is to determine the length of a garland to be fitted into an arch over the entrance of a church. Felix Schlosser reports on his task and the use of MathCityMap in the classroom below.
How did you come across the MathCityMap project? How do you use MCM?
I came across MathCityMap via a teacher training course. Ms. Reit from Frankfurt also presented many other interesting ideas there. Out of curiosity, I then deepened my knowledge in an independent MCM training. However, since it took me more than a year to start using it in the classroom, I attended another three-part training course from MathCityMap, which was structured and went into detail about everything that was important for smooth operation.
I presented Math-City-Map in a regional group for the Berlin project “Mathematikunterricht-konkret” and in order to put ourselves in the students’ shoes, we tried out a trail at the Gendarmenmarkt. This inspired me to create tasks myself for the three-part advanced training, for reuse near my school, of course. This way I can also present them at the professional conference and let them try them out.
What can learners take away from working on the task?
The rainbow flag on the church gave me the idea for the task. The theme is very appealing as a symbol of diversity. What is special about the task is that in addition to finding the necessary formula for the circle calculations, the students are also challenged to find the necessary measurements. What values can we get even though we can’t measure directly? Thus the task is graded, one has to think on different levels – literally. The measures can only be determined indirectly and only approximately. This increases the puzzling character and consequently the motivation to solve the task.
