What are two integers that make a zero pair?
| Aa | Bb | Dd |
|---|---|---|

What are examples of zero pairs?
Remember that each member of a pair of numbers such as –3 and 3 is called the opposite of the other number. The pairs are also called “zero pairs” because their sum is zero. Example: In one game, you scored 9 points. Then, you made mistakes that lost 3 points.
Why do you have to add zero pairs before subtracting?
You can’t take 2 positives (yellows) away because you don’t have any. Therefore, you will need to add some zero pairs. These do not change the value of -5 because they are worth zero. If too many zero pairs are added, they can be removed after working out the problem.
Is zero a integer number?
As a whole number that can be written without a remainder, 0 classifies as an integer.
What is the pair of integer whose sum is 0?
negative
The sum of the positive counting number and the negative counting number gives the value zero. There are lots of similar pairs eg: (-1, 1), (-2, 2), (-3, 3), (-4, 4) etc.
How to add and subtract integers using zero pairs?
How to add and subtract Integers? Using integer dots to demonstrate the adding of integers using zero pairs. The positive dots and negative dots cancel to leave the answer. Examples: 6 + 2 =-6 + (-2) = 6 + (-2) =-6 + 2 = -4 + -3 =-2 + 5 = -3 + 1 =-2 + -2 =-3 + 3 = Show Step-by-step Solutions
Can you write 3 positives and 3 zero pairs?
Students will collectively say no. Ask students to ponder what should be done. Many students will tell you to write 3 positives and take away 3 zero pairs. Do not shy away from showing students why this will not work. Use their previous learning over addition of integers to help prove that scenario incorrect.
Can you pair negative and positive numbers to get a sum of zero?
If students are unaware of pairing a negative and a positive number together to get a sum of zero, then they will struggle with this. However, this is a great teachable opportunity to introduce zero pairs to those who do not know this concept.
When do you use zero pairs in swbat?
SWBAT use zero pairs to apply and extend previous understandings of addition and subtraction to add integers. Zero pairs! These are a fun and rigorous way to help kids understand integers.
