What are integer tiles?
Integer tiles are one way of using a material representation to introduce the concept of adding and subtracting integers. This model can be useful for working on the type of problem that many students find harder, that is problems like -4 + -5.
What are counters in math?

How do you use integer chips?
HOW TO USE THIS PRODUCT Teach students how to use Integer Chips to add integers by moving red (negative) and yellow (positive) chips into rows, and taking out the Zero Pairs. Students love moving the chips around the board on each slide.
How many negative counters do you need to represent-4?
Start with four negative counters to represent -4 and three positive counters to represent +3. Mark the zero pairs. In the above figure, if you remove the three zero pairs, the result will be one negative counter.
How do you find the value of a negative counter?
Start with four negative counters to represent -4 and three positive counters to represent +3. Mark the zero pairs. In the above figure, if you remove the three zero pairs, the result will be one negative counter. So, the answer is -1.
What is the sum of integers with different signs?
ADD AND SUBTRACT INTEGERS USING COUNTERS We can use the following colored counters to model the sum of integers with different signs. When you add a positive integer (yellow counter) and a negative integer (red counter), the result is 0. 1 + (-1) = 0
