## 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!
