Students will understand the Binary (Base 2) Number system. They will know how to count in Binary. How to convert from Decimal 2 Binary. How to convert from Binary 2 Decimal. How to Add and Multiply in Binary. This lesson is the 1 of 4 in the Digital Logic Project, and leads to Building a Digital Logic System
Introduction: This lesson is designed to introduce students to the Binary (base 2) number system. They will know how to count in Binary. How to convert from Decimal 2 Binary. How to convert from Binary 2 Decimal. They will know how to Add and Multiply in Binary.

How I Teach This Lesson: I start by giving my students an Entry Ticket where they can spend 5-6 min looking at a site to give them an introduction to binary numbers.
Then I start the slide presentation, where I "Ham" it up, telling the students that I'm a Psychic and can read their minds. I will let a student pick a number, and then click through the 6 slides and then "guess" their number. Then I'll do it again with 3-4 more students as time allows.
Then I'll work through a lecture 20-30 min, and then work a few of the problems with the students, and then I'll let them review the slides and Entry Ticket web sites for about 5 min. During this time I will walk around and make sure my students understand.
Then I point them to the Google Quiz and have them take #1 and #3. then maybe the next day before I start the next lesson in this module, I'll have them take Quiz 2 and 4.
Good Luck, Have Fun.
Prior Knowledge: Students should have an understanding of how the Base 10 number system works. How and why we carry when we count from 9 to 10 or 99 to 100. Understand the concept of the "One's", "Ten's" and "Hundred's" place values.
