Using two-sided counters is another way in addition to using a number line to model adding and subtracting integers.

How to use counters to subtract integers. Then we subtracted 3 3 negatives from 5 5 negatives to get 2 2 negatives. First we subtracted 3 3 positives from 5 5 positives to get 2 2 positives. In the above figure if you remove two zero pairs the result will be three positive counters.

For Students 5th - 6th. The other color red will represent the negatives. Each example used counters of only one color and the take away model of subtraction was easy to apply.

Tell students that another way to model addition of integers is to use counters Show students that the light colored empty circlecounter represents a positive and a dark colored countercircle represents a negative Show students that when adding integers we can use the counters by just putting out what the problem says and then removing the parts. 5 - 2 5 -2 Start with five positive counters to represent 5 and two negative counters to represent -2. Students use two-color counters to find the difference in 4 subtraction problems with integers.

First we subtracted 3 3 positives from 5 5 positives to get 2 2 positives. Get Free Access See Review. I show students how they will draw pictures to show what they do with their counters.

Middle school students want to have some fun too but giving up instructional time is impossible. We let one color blue represent positive. I explain that if we add 1 -1 the yellow.

Write the given subtraction as addition. Middle school students want to have some fun too but giving up instructional time is impossible. In this subtraction of integers activity students write a subtraction expression for 4 blackwhite counters.

So the answer is 3. Then we subtracted 3 3 negatives from 5 5 negatives to get 2 2 negatives. Now lets see what happens when we subtract one positive and one negative number.

Add and Subtract Integers with Red and Green Candy Use red and green MMs jelly beans or paper scraps as positive and negative counters for a hands-on concrete engaging lesson. Each example used counters of only one color and the take away model of subtraction was easy to apply. If we have one positive counter and one negative counter the value of the pair is zero.
