## TEJ3M/4M – Sept 22, 2014

IMPORTANT:  THE STUDENTS WILL BE HAVING AN IN-CLASS OPEN BOOK ASSIGNMENT TOMORROW COVERING WHAT THE STUDENTS HAVE LEARNED ABOUT IN NUMBER SYSTEMS SO FAR (CONVERTING BINARY, DECIMAL, OCTAL AND HEX NUMBERS).

I began the class today by mentioning to the students that I would be away from school tomorrow for a conference.  I then mentioned that they would be having an in-class open book assignment on what we have learned so far in number systems (this includes the lesson we did today as well).  The students can use their notes to help them complete the assignment.  This is an individual assignment so students are not to talk and are to show all of their work for each question.

After talking to the students about the assignment, I then did a lesson which was a continuation of the lesson we did on Fri Sept 19 titled “Converting Octal & Hex to Binary (and vice versa) – continued”.  I only had 2 more examples to do but I wanted to make sure the students had them for their notes.  Once I finished the lesson, I then told the students that we would be doing an activity which would help them with their assignment tomorrow.  I put up 4 questions on the board and asked the students to convert them.  The assignment tomorrow will be just like this activity.  I had the students try to solutions to the 4 questions at their desks and then we took them up as a class (I will post the questions with solutions below).  I then gave the students a few handouts.  The first handout was a summary of all the conversions we have done which students can use to help them study.  The second handout has conversions for the first 32 decimal numbers and related binary, octal and hex numbers in a table.

Below you will find a copies of the handouts/worksheets that were distributed/assigned in today’s class.

Sept 22 – Lesson – Converting Octal & Hex to Binary (and vice versa) – continued (this is continued from the lesson on Fri Sept 19)

Try These (practice questions for converting binary, decimal octal and hex) (these are the 4 questions we did in class with solutions)

Sept 22 – Handout – Binary, Octal, Decimal & Hexadecimal Review (I gave this to the students as an extra review)

Sept 22 – Handout – Binary, Octal, Decimal & Hexadecimal Conversion Table (this shows the conversions for the first 32 decimal numbers)
