Your name: Shawn Fan School, grade & course: Hugh Boyd Secondary School, Math 9 Topic of unit: Solving Linear Equations (1) Why do we teach this unit to secondary school students?  Solving Linear Equations is a crucial part of the secondary school curriculum, acting as a bridge for students transitioning from reasoning with numbers to reasoning with unknowns. This topic prepares students for understanding more complex functions, equalities, and inequalities, and finds applications in fields like science, finance, and engineering. The beauty of linear equations lies in their simplicity and universality. They represent a fundamental principle of reversing or undoing mathematical operations, and can model real-life situations, such as travel, money, age, or number problems. By mastering this topic, students gain a powerful tool for problem-solving and logical thinking, skills that are not only useful in mathematics but also in everyday life. Thus, the study of linear equations is ...

As a teacher, the examples presented in the article highlight the nuanced ways in which language and images in mathematics textbooks can influence students' perceptions, positioning them in relation to mathematics, their peers, teachers, and the world outside the classroom. The framework for examining textbook language and its impact on learners' experiences underscores the importance of considering the socio-cultural context and linguistic choices in shaping students' engagement with mathematical concepts. As a former student, I know how these subtle linguistic and visual cues in textbooks might have influenced my understanding and attitude toward mathematics. The emphasis on depersonalization and abstraction in mathematical reasoning, as discussed in the article, resonates with the often perceived difficulty of making mathematical concepts relatable to real-life experiences. It prompts reflection on how the language used in textbooks can either bridge or widen the gap bet...

The state of flow is a profound and fulfilling experience that transcends specific domains, encompassing various aspects of life such as art, sports, and work. Personally, I have experienced a state of flow during activities that align with my skills and provide a challenging yet achievable environment. This often occurs during problem-solving. The idea that flow can be connected with mathematical experiences resonates with my own encounters with mathematics. Mathematical problem-solving, particularly when dealing with challenging yet solvable problems, can induce a state of flow. The process of grappling with mathematical concepts, experimenting with different approaches, and experiencing the "aha" moment when a solution is found mirrors the characteristics of flow described in the talk. I believe it's entirely possible to create conditions that facilitate a flow state for students. As teachers, we can play a crucial role in designing lessons that strike a balance betwee...

To find a fraction between 5/7 and 3/4 using a common denominator, express 5/7 as 20/28 and 3/4 as 21/28. Since there is no integer between 20 and 21, expand further to 40/56 and 42/56. One possible answer is 41/56. However, if the numerator is 11, the least common multiple of 5 and 3 is 15. In this case, we cannot find an integer that fits in. Stop 1: Dave highlights the issue of students memorizing procedures without truly understanding the underlying concepts. This prompts reflection on the traditional teaching methods and the importance of fostering a deep comprehension of mathematical principles. Stop 2: The discussion about the statement "2 + 3 = 5" as a profound concept that extends to various situations challenges the perception of basic arithmetic as isolated facts. It encourages educators to delve deeper into the fundamental principles and implications of seemingly simple mathematical expressions. Stop 3: The emphasis on awareness in learning fractions, particularly...

In the context of the article, "arbitrary" refers to those aspects of mathematics that are based on conventions, names, or memorization. These are elements that students must accept and adopt without much room for interpretation. They include things like mathematical notations, terms, and established rules. As a teacher, I need to recognize that these elements are essential, and my role is to inform students about them. However, I should also be aware of the potential challenges in this area, especially for students who may struggle with memorization. To address this, I could consider innovative teaching strategies, mnemonic devices, and frequent practice to help students grasp and retain these arbitrary elements effectively. Conversely, "necessary" elements in the article refer to mathematical properties that can be understood and worked out through reasoning and problem-solving. These are the underlying principles, relationships, and concepts that form the foundat...
