Math

Hello class!

Today's lesson is on learning how to add and subtract integers. You will be learning a song that will help you add and subtract integers. Its a quick and easy song to learn and I promise you this song will help you for the rest of your life! Are you ready to start singing class?! Lets go!

First I will explain what are integers and a few definitions.

Definitions

• The number line goes on forever in both directions. This is indicated by the arrows.
• Whole numbers greater than zero are called positive integers. These numbers are to the right of zero on the number line.
• Whole numbers less than zero are called negative integers. These numbers are to the left of zero on the number line.
• The integer zero is neutral. It is neither positive nor negative.
• The sign of an integer is either positive (+) or negative (-), except zero, which has no sign.
• Two integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line. One will have a positive sign, the other a negative sign. In the number line above, +3 and -3 are labeled as opposites.

This right here is the lyrics to the song. The rhythm or tune to the song is the same as the song "Row, Row, Row Your Boat". So if you know that song, then you can defiantly sing this new song. The name of this song that you are about to sing is called "Same Signs Add and Keep". Here is the lyrics to the song:

Same signs, add and keep                            

Different signs, subtract

Use the sign of the bigger number

Then you'll be exact!

See, that's all students, it's short and simple and easy to remember.
