AIM: How can a chip model or number line be useful in finding a subtraction algorithm?
Class: Like we did with the addition algorithm, we will investigate how integer chips and numbers can be used to model integer subtraction problems. From here, we can derive an algorithm that can be used for all rational numbers. Resources: https://www.khanacademy.org/math/arithmetic/absolute-value/adding_subtracting_negatives/v/adding-and-subtracting-negative-number-examples Make sure to check off "Subtraction" and "Negatives" on the left. Adjust the level of difficulty as you get better. http://www.thatquiz.org/tq-1/math/arithmetic/ ## Leave a Reply. |
