  3. Global Classroom • McRel Evaluation instrument • Standard II: Teachers establish a respectful environment for a diverse population of students • Teachers embrace diversity in the school community and in the world. Teachers demonstrate their knowledge of the history of diverse cultures and their role in shaping global issues. They actively select materials and develop lessons that counteract stereotypes and incorporate histories and contributions of all cultures. Teachers recognize the influence of race, ethnicity, gender, religion, and other aspects of culture on a student’s development and personality. Teachers strive to understand how a student’s culture and background may influence his or her school performance. Teachers consider and incorporate different points of view in their instruction.

  4. McRel Evaluation instrument • Standard III: Teachers know the content they teach • Teachers know the links and vertical alignment of the grade or subject they teach and the state standards. Teachers understand how the content they teach relates to other disciplines in order to deepen understanding and connect learning for students. Teachers promote global awareness and its relevance to the subjects they teach. • Teachers incorporate 21st century life skills deliberately, strategically, and broadly into their teaching. These skills include leadership, ethics, accountability, adaptability, personal productivity, personal responsibility, people skills, self-direction, and social responsibility. Teachers help their students understand the relationship between the state standards and 21st century content which includes global awareness; financial, economic, business, and entrepreneurial literacy; civic literacy; and health awareness.

  5. GeoMath • A series of 7 lessons (warm-up, review and project) • Geography + Math = a Global Classroom

  6. GeoMath Lessons • Angles of elevation & angle of depression using the world’s tallest buildings • Calculating the perimeter and area using flags of the world • Time Zone math • Calculating percentages while making a cartogram • Linear regressions and population predictions • Finding the circumcenter to determine a distribution center in Africa • Making choropleth maps using various methods of calculating the data

  7. Angles of elevations and depressions

  8. Enrichment How would the angle of depression change if the student moved from the top observation deck to the lower observation deck? How would the angle of depression change if the student were riding on the Eye of London?

  9. Area and Perimeter of Flags

  10. Time Zone Math

  20. Different ways of “slicing” data • The Data {42, 50, 55, 57, 61, 77, 79, 97} • Equal interval • Three classes based on range 40 to 100 • {42, 50, 55, 57} {61, 77, 79} {97}

  21. Different ways of “slicing” data • Quantile • Quartiles (lowest 1/4 of observations, next 1/4, …) • {42, 50} {55, 57} {61, 77} {79, 97} • Natural breaks • {42} {50, 55, 57, 61} {77, 79} {97}

  22. Different ways of “slicing” data • Standard deviations • Mean = 64.75, Std. Dev. = 15.977 • {42} {50, 55, 57, 61} {77, 79} {97}

  23. Quintiles Natural Breaks Equal Interval
