8/23/24 – Pixel Drawing Protocol

Summary: Today we continued working our line drawing protocols and started on our pixel drawing protocols (see Google Classroom for more details).

Instructions…
Create a protocol to take any black and white pixel drawing on a 10×10 grid and turn it into binary.

Rubric…
Same as all of the other protocols (see Google Classroom for more details)

Homework: Line Drawing Protocols (due Monday morning). Pixel Drawing Protocols (due Tuesday Morning) (CA-07)

8/22/24 – Line Drawing Protocol

Summary: The fist thing we did today was register each student on the College Board Website (code: 2D9WVJ). If you’ve every had an AP class before or taken the SAT test please do not create a new account, simply sign up using your existing account. If you have never made a College Board account you will need to create a new account. Please write down the email address and password that you used so that you don’t forget it!

Today we worked on our “Square Grid Line Drawing Protocol” (see the rubric and details in Google Classroom).

Instructions…

Create a protocol to take any line drawing on a 12×12 grid and turn it into binary. The endpoints for every line segment of the drawing will be on a lattice point (aka on the intersection of the grid lines)

Rubric…

  • Functionality – The protocol accomplishes the task at hand. It always works.
  • Clarity – The protocol is written clearly and is easy to understand
  • Formatting – The document looks polished and professional.
  • Efficiency – The protocol uses as few bits as possible.
  • Ease of Use – It is fast and easy to use.
  • Examples – The protocol includes at least one example.
