These activities correspond with the Negative Functions video playlist on our YouTube Channel (https://bit.ly/3hG1OL5).Students learn how to add and subtract using negatives on a number line, on a chip board and with the traditional algorithm. We examine the patterns to build the algorithm for multiplication of negatives. Then use that algorithm with fact families to build the division of negatives algorithm.Videos can be accessed via the QR code on each page. All answers are in the correspondin
