Reflection: Flexibility Finding the Distance Between Integers On a Number Line - Section 1: Introduction

 

The problems in the introduction are presented to make sure students can use a number line to count distances between points.  (If you see your students get this, I wouldn't spend too much time on any of these problems.  I would let them jump straight to the problem solving section.).  Quite a few of my students had a unit of integer operations at the end of their sixth grade year.  They wanted to ignore the number line and just solve the subtraction problems.  I guess that is okay, but I noticed that many of them were making mistakes with their integer subtraction.  I had to keep reminding them to check their answers using the number line.  

Also think of this introduction as something that could be "re-mixed".  You may want to make a quick game out of finding the distances.  There may be no need to provide students with anything other than a number line and then ask students find the distances by posting them on the board.  A high paced game makes this a lot more fun than how it is presented in the resource.

 

Also, if you students quickly grasp the concept, move on to the problem solving section!

Finding the Distance Between Integers On a Number Line

Unit 1: Rational Number Operations
Lesson 2 of 27

Objective: SWBAT determine the distance between two integers on a number line and express the distance as the absolute value of their difference

Big Idea: Number line models allow students to easily find distances between points and relate the distance as the absolute value of their difference.
