Geom7-1
1) The document provides instructions for a geometry class activity where students cut a triangle out of orange paper, label the angles with letters, rip off the angles, and tape them back together with the outer corners facing in to observe properties of the angles.
2) Students are then asked to make observations about the angles and not write "IDK".
3) The document concludes by mentioning exterior angles and assigning homework problems from section 7.1 of the notes due on Monday.
Geom13-1
This document contains notes from a geometry lesson on graphing lines. It includes examples of graphing lines by writing out the steps, using different methods like a "defensive lineman" or "ballerina." It also covers finding intercepts, graphing circles, and using a calculator. The agenda is to cover Chapter 13 and review for a final. Students are assigned exit slip problems graphing an equation using a table and checking on their calculator.
Geom5-6
This document contains notes from a geometry lesson on five ways to prove that a quadrilateral is a parallelogram. It lists the five properties: 1) both pairs of opposite sides are parallel, 2) both pairs of opposite sides are congruent, 3) one pair of opposite sides are parallel and congruent, 4) the diagonals bisect each other, and 5) both pairs of opposite angles are congruent. It directs students to examples in the textbook and ends with an exit slip quiz and assigning homework problems.
Geom5-4
This document provides geometry problems and instructions for students. It includes an example problem to find the measure of an angle within a diagram. It defines key terms like convex polygon and diagonal. It lists the exit slip problem and homework problems assigned, which are problems from a textbook on pages 237 and 238, with the homework due on Wednesday.
Geom5-5
1) The document is notes from a geometry class that discusses properties of polygons.
2) It provides bell work asking about the sum of angles in triangles, quadrilaterals, and pentagons.
3) The agenda lists practicing problems, completing a worksheet on properties of quadrilaterals, and an upcoming quiz.

A 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.
