This document contains notes from a math lesson on identifying proportional and non-proportional relationships in graphs. It includes homework assignments to complete problems sets and exit tickets. The lesson discusses representing proportional quantities with a line graph passing through the origin, and a common student mistake of thinking relationships are proportional if points just lie on a line instead of passing through the origin. It emphasizes that for proportional relationships, the graph points must lie on a straight line that goes through the origin.

Functions based algebra 1 pesentation to department 042312
This document provides an overview of a teacher's training, philosophy on teaching algebra, units taught, and results from implementing a functions-based approach to teaching algebra. The teacher has taken several courses related to curriculum, instruction, and assessment. Their philosophy is to use a functions-based approach to help students make their own associations and build patterns, using visualization and context to give meaning to algebra. Units covered include families of functions, linear, absolute value, systems, exponential, quadratic, polynomial, and radical functions. Test results showed students scored higher using the functions-based approach, particularly co-taught students. The teacher reflects on personal and professional growth from implementing this approach.
Module 1 lesson 4
This document contains notes from a mathematics lesson on equivalent ratios. The lesson defines equivalent ratios as ratios where corresponding terms are in the same proportion, using a constant value (c) to relate the two ratios. Students practice identifying equivalent ratios using tape diagrams and the definition. They determine if sample ratios are equivalent or not, and justify their answers. The document provides examples and exercises for students to apply the concept of equivalent ratios.

https://app.box.com/s/y977uz6bpd3af4qsebv7r9b7s21935vdA Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

What is a common mistake a student might make when deciding whether a graph of two quantities shows that they are proportional to each other? Both graphs can have points that lie on a straight line, but the graph of the quantities that are proportional to each other also goes through the origin. In addition the graph could go through the origin, but the points do not lie on a straight line.
