exterior angle theorem practice problems: The Baller Teacher Playbook Tyler Tarver Ed S, 2021-02-18 Does your classroom run the way you want? Most people enter the teaching profession wanting to make a difference in young people's lives. However, more and more teachers feel lost, frustrated, and overwhelmed with everything they're required to do. It's hard to be successful without a clear plan on getting control of your classroom, empowering your students, and making the learning experience more enjoyable for you and your students. These 18 chapters are crucial for any educator who wants to take their teaching to the next level. Teacher, Principal, Director, Dean, and YouTube/TikTok teacher, Tyler Tarver knows that education is more than just standing in front of students lecturing them on a specific topic - it's a culture of learning that educators foster to train the next generation. If you are attempting to be the best educator you can in the environment you're in, you need ideas and encouragement from someone who's been exactly where you are. Even if you had the time, money, and support we know teachers deserve, we know that applying any knowledge always has a greater impact when you're able to give personal and practical application to the ideas you know matter. Besides sitting through 60+ hours a year of professional development, there is another way to incrementally improve your teaching week after week. Spoiler Alert: It can also be fun. Tyler Tarver learned how to create the culture he wanted in his classroom. He was able to pass this on to any educator who wanted to get excited about teaching and have a deeper impact on their students. He wrote The Baller Teacher Playbook to teach others what it takes to expand your teaching and create a community of happy and engaged learners. These short, weekly chapters and accompanying resources will add enormous value to your classroom and the school you work for. In this 18-week guide, readers will be introduced to the top areas where truly successful teachers and their students excel: Reason vs Excuses: How do you overcome the hurdles inherent in education? Fun: How do you get yourself and students excited about learning? Creativity: How do you create a culture where every day is unexpected but not chaotic? Positivity: How can we roll with the punches but not have to fake it? Authenticity: How can I be myself but genuinely connect with young people? Leadership: How do I get my students to lead without me? Collaboration: How do I work with my administrators, colleagues, and parents to better every student's education? Diversity: How do I help build empathy and understanding among myself and my students? Development: How am I always getting better? Plus more! The Baller Teacher Playbook is the must-have guide for anyone who feels lost or overwhelmed by the current educational climate, even if they have been teaching for years. Learn from a fellow educator who had their fair share of mistakes and successes through the simple but effective tactics shared in these pages. Take things further: If you want to move forward even faster as an educational professional, read a chapter once a week with your team, and come together at weekly meetings to discuss experience, ideas, triumphs, and a community of educators trying to improve themselves and their classroom. |

exterior angle theorem practice problems: A Decade of the Berkeley Math Circle Zvezdelina Stankova, Tom Rike, 2008-11-26 Many mathematicians have been drawn to mathematics through their experience with math circles: extracurricular programs exposing teenage students to advanced mathematical topics and a myriad of problem solving techniques and inspiring in them a lifelong love for mathematics. Founded in 1998, the Berkeley Math Circle (BMC) is a pioneering model of a U.S. math circle, aspiring to prepare our best young minds for their future roles as mathematics leaders. Over the last decade, 50 instructors--from university professors to high school teachers to business tycoons--have shared their passion for mathematics by delivering more than 320 BMC sessions full of mathematical challenges and wonders. Based on a dozen of these sessions, this book encompasses a wide variety of enticing mathematical topics: from inversion in the plane to circle geometry; from combinatorics to Rubik's cube and abstract algebra; from number theory to mass point theory; from complex numbers to game theory via invariants and monovariants. The treatments of these subjects encompass every significant method of proof and emphasize ways of thinking and reasoning via 100 problem solving techniques. Also featured are 300 problems, ranging from beginner to intermediate level, with occasional peaks of advanced problems and even some open questions. The book presents possible paths to studying mathematics and inevitably falling in love with it, via teaching two important skills: thinking creatively while still ``obeying the rules,'' and making connections between problems, ideas, and theories. The book encourages you to apply the newly acquired knowledge to problems and guides you along the way, but rarely gives you ready answers. ``Learning from our own mistakes'' often occurs through discussions of non-proofs and common problem solving pitfalls. The reader has to commit to mastering the new theories and techniques by ``getting your hands dirty'' with the problems, going back and reviewing necessary problem solving techniques and theory, and persistently moving forward in the book. The mathematical world is huge: you'll never know everything, but you'll learn where to find things, how to connect and use them. The rewards will be substantial. In the interest of fostering a greater awareness and appreciation of mathematics and its connections to other disciplines and everyday life, MSRI and the AMS are publishing books in the Mathematical Circles Library series as a service to young people, their parents and teachers, and the mathematics profession. |
