Reflection: Flexibility Where Do We Go From Here? Adding Integers on the Number Line - Section 2: Introduction


It is the beginning of the year and I am in the thick of teaching and re-teaching classroom procedures.  This takes time.  Also, I am adjusting from the fact that my class time is 1/3 less than that of last year.  That being said, I had to combine the introduction section and the problem solving section to make up for "lost" time.  We worked on the introduction problems using our pointers on the number line.  Knowing that I wanted to have a lot of time for students to do their independent work, I asked the questions that belong in the problem solving section during once we solved the introduction problems.  We skipped the actual problem solving section itself but still answered the essential questions.

Also, it is important and helpful (I think) to provide a real-world context for the essential question.  A simple question might be "I have $2500 in my checking account.  Is it possible for me to add a value to my account and end up with less?"

Where Do We Go From Here? Adding Integers on the Number Line

Unit 1: Rational Number Operations
Lesson 3 of 27

Objective: SWBAT determine when a sum is less than or greater than the first addend using a number line

Big Idea: What happens when we add a positive or negative number? Is the result a lesser or greater value? Travel along a number line to find out.
