"S u mmary an d Teach er’s Gu id e: Th e Pyth agorean Th eorem, Geometry’s Mos t Elegan t Th eorem Sandra Haupt, mail.colonial.net/~shaupt Hello, and welcome to this BLOSSOM learning module. I’ve been a teacher of mathematics at Concord-Carlisle High School in Massachusetts for the past 10 years. In previous incarnations I was a geophysicist in the petroleum industry in Colorado and worked in Environmental Law in Vermont. I have always been interested in the history of mathematical thinking and the development of mathematical concepts, and make a point to emphasize contributions from both Western and non-Western civilizations. This learning module teaches students about the history of the Pythagorean theorem, along with proofs and applications. Feel free to use your own motivational ideas and tailor it to your students! This lesson is geared toward high school Geometry student that have completed a year of Algebra. The video portion is about thirty minutes, and with breaks could be completed in 50 minutes. (You may consider completing over two classes, particularly if you want to allow more time for activities or do some of the enrichment material). These activities could be done individually, in pairs, or groups, I think 2 or 3 students is optimal. The materials required for the activities include scissors, tape, string and markers. Calculators are optional. This lesson addresses the national standards of the National Council of Teachers of Mathematics and the Mid-continent Research for Education and Learning, specifically:
• • •

Analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationships Use visualization, spatial reasoning, and geometric modeling to solve problems Understand and apply basic and advanced properties of the concepts of geometry; Use the Pythagorean theorem...

Lesson 2 - The Importance of Team Work When a goose falls out of formation it suddenly feels the drag and resistance of flying alone. It quickly moves back to take advantage of the lifting power of the birds in front. Outcome if we had as much sense as geese we would stay in formation with those headed where we want to go. We are willing to accept their help and give our help to others. Lesson 3 - The Importance of Sharing when a goose tires of flying up front it drops back into formation and another goose flies to the point position. Outcome It pays......

#### How to Create a Lesson Plan

...There are many elements to take under consideration while creating a lesson plan, however these elements are important for different reasons and when combining the elements in the right order you can produce what every teacher hopes for: measurable student learning.

The first element that should appear in a lesson plan is the Common Core Curriculum Standards. This should be first within ones lesson plan because it withholds the standards that clearly communicate was is expected of the student at each grade level within the different subject matters. This element is important because it realizes that both content and skills are important. CCSS are also important because it sets a guideline for what students should be learning and include rigorous content and application of knowledge through high order skills that are aligned with future college and work expectations. The second element that should appear in a lesson plan is that of Performance and Learning Outcomes, or in different terms the objectives and goals. This should appear second because it outlines the topics and material that the students will be learning with a certain amount of time; also showing them......
