For example, 5 - (-5), would require five yellow chips to start and would also require the removal of five red chips, but there aren't any red chips! Adding or subtracting zero (a red chip and a yellow chip) has no effect on the original number, so we could add as many zeros as we wanted to the pile, and the number would still be the same.

In the first set where the range is -9 to 9, the difference between the two numbers is always 1.
With the largest range, a difference of up to 5 is allowed.
You may also want to get one of those giant integer number lines to post if you are a teacher, or print off a few of our integer number lines.
You can also project them on your whiteboard or make an overhead transparency.
One hugely important reason is that there are many high school mathematics topics that will rely on a strong knowledge of integers and the rules associated with them.
We've included a few hundred integers worksheets on this page to help support your students in their pursuit of knowledge.If you remove the zeros, you don't change the answer at all.The benefit of removing the zeros, however, is that you always end up with only one color and as a consequence, the answer to the integer question.In our example 5 - (-5), you would add 5 zeros, so that you could remove five red chips.You would then be left with 10 yellow chips (or 10) which is the answer to the question.Adding with two-color counters is actually quite easy.You model the first number with a pile of chips flipped to the correct side and you also model the second number with a pile of chips flipped to the correct side, then you mash them all together, take out the zeros (if any) and voila! Since there are a few confused faces in the audience, let us explain a little further.Subtracting Integers Subtracting with integer chips is a little different. To subtract with integer chips, begin by modeling the first number (the minuend) with integer chips.Next, remove the chips that would represent the second number from your pile and you will have your answer. This works beautifully if you have enough of the right color chip to remove, but often times you don't.They should quickly realize that negative numbers are counter-intuitive because they are probably quite used to larger absolute values meaning larger numbers.The reverse is the case, of course, with negative numbers.
