Sky Typing

Discover the challenges of aerial message delivery with Sky Typers. This interactive experience explores the transformation of a message meant to be viewed from a plane. Learn how to create ordered pairs for the letters in "MATH" and how to adjust the message's position and size for optimal visibility. From reflection and rotation to dilation and translation, we guide you through the steps to communicate your message effectively, all while mastering algebraic transformations. Can you determine the best way to convey your message?

Presentation Transcript

  1. Sky Typing http://robertkaplinsky.com/work/skytypers/

  2. Plot points & Make a list of ordered pairs for each letter: M – A – T – H – Would this message look different if you were viewing it from a plane above the message instead of on the ground?

  3. UH OH – The message was supposed to be read horizontally from east to west instead of vertically from north to south.

  4. UH OH – The message is too small. It needs to be 50% larger!

  5. UH OH – This is a message for Los Angeles and they can’t see it well because it’s a few miles away. It needs to move 3 units west and 10 units north.

  6. We’ve moved it! Now how do we tell the computer to move from the original points to the finished points in ONE algebraic command?

  7. Algebraic Transformations • Reflection across the x-axis • 90 Clockwise Rotation about the origin • 50% larger Dilation • Translation 3 units left, 10 units up • One transformation to tell the computer in ONE step
