1. Zoom In Inquiry “I Spy” Geometry in Primary Sources

2. BIG Question: What might primary sources tell us about geometry? Determine what 2-D and 3-D shapes you see and think about what questions you can ask to get the big picture.

3. Key Vocabulary *line*line segment *intersecting lines *parallel lines *perpendicular *vertex/vertices *angles ~ right, acute, obtuse *polygon *triangle ~ right, equilateral, isosceles, acute, obtuse, scalene

4. More Key Vocabulary *quadrilateral*square *rectangle *parallelogram *trapezoid *rhombus *pentagon*hexagon*octagon *decagon *circle *rectangular prism *cube *cylinder *cone *sphere

5. What 2-D and/or 3-D shape(s) do you see?

6. What additional 2-D and/or 3-D shapes do you see now?

7. Describe who or what you see in this image now? When do you think this image was taken?

8. Describe who or what you see in this image now? When do you think this image was taken? How does geometry in primary sources show that math is all around us?

11. What might this last image tell us about geometry in primary sources? Does it show “how” math is all around us?

12. The End Remember to for math all around you, everyday!
