Nov 21: Exit slip

For my inquiry project, I am currently in the research phase. I have shifted my focus away from classroom layouts to exploring the role of formative assessment in mathematics, specifically the effectiveness of exit slips in promoting consolidation and reflection. One key issue I have observed is that many students struggle to answer the simple question: "What did you learn today?" when it comes to math. Susan also shared a story where  her son, when asked what they did in class, replied, "More math." This highlights a potential gap in formative assessment, particularly at the end of lessons, where there may be a missed opportunity to help students consolidate the concepts covered during the lesson. So far, I have already come across several articles and videos on the topic. I am in the process of reviewing them to select 8 for my annotated bibliography.

In the second half of class, we focused on the topic of dividing by zero. We discussed two main arguments. First, dividing by zero is non-invertible. Second, division by zero approaches both negative and positive infinity simultaneously. As part of the activity, we also engaged in free writing on the topic, with the option to write poetry. I wrote the following poem:

Zero as we know in modern times 

Is in the middle when we align 

All the number on a number line 

A comfort we all find

But when we divide, there are wars,

A paradoxical spot, ceilings and floors, 

Where positive and negative infinities score

All at the same time
