Essential Question: How do Computers Count?
Source: Original material
Format: Slide Presentations, "Simon Sez", Pair Share, "Simon Sez", Group Practice
Learning Objectives: Students will:
Learn Latin: digit = finger and index = pointer
Learn the Assyrian "finger pad" counting system
Combine "finger pad" with "twelves" to count to 156
Learn how computers use binary digits (bits)
Use fingers to count to 31 with one hand
Use arms (2 people) to count to 15
Summary: Students can be intimidated by technology. This exercise uses anthropogenic (human body-based) counting as a bridge to understanding the math and engineering of computers, and also gives students permission to "give the finger" to the teacher (count 4). It's fun, and it provides opportunities for students with different skill specialties (math, dexterity, pattern recognition, ability to focus and do what they see) to shine.
