Subtracting Integers With Color Counters Extra Zeros Needed Physics Take away the second number. so we need to take away 3 3 positives. but there are no positives to take away. add neutral pairs until you have 3 3 positives. now take away 3 3 positives. count the number of counters that are left. −5−3=−8 − 5 − 3 = − 8. the difference of −5 − 5 and 3 3 is −8 − 8 . Addition and subtraction: two color counters and number lines. these are similar to models used by ou. elementary colleagues and should be familiar to our students.when we model addition of integers with two color counters, we must first establish which color represe. ts positive values and which color represents negative v. Dr. powell uses the two color counter manipulatives to show how you can subtract integers. when you finish watching this video, please complete our brief sur. 5 5. negatives to get. 2. 2 2. negatives. each example used counters of only one color, and the "take away" model of subtraction was easy to apply. now let’s see what happens when we subtract one positive and one negative number. we will need to use both positive and negative counters and sometimes some neutral pairs, too.
