[] = = =**Adding Integers with Number Lines ** = We can learn how to add and subtract integers by moving up and down our number line. Remember, to the left of zero are negative numbers and to the right are positive. This is not the only way we can add or subtract integers, check out another way with algebra tiles. media type="youtube" key="ZxbXjORORSU" height="390" width="480" media type="youtube" key="RDw3Gq-heTw" height="390" width="480"

** Adding Integers with Algebra Tiles. **
Algebra tiles are a tool that we can use to model adding and subtracting integers. Some people like them, some people don't. We will try them out and you can decide if you like them or would prefer to use the number line method as you saw above or memorizing the rules, another method. In our class, we will use the dotted tiles to represent positive integers and the smooth tiles to represent negative integers. We will not use the coloured tiles that the teacher in this video uses. They will work the same though! One dotted tile (positive one) combined with one smooth tile (negative one) makes zero; they cancel each other out. We call this the zero principal. media type="youtube" key="Js9sVSFpyFE" height="390" width="640"
