AIM: How is the multiplication of integers represented on a number line a chip board?
HW: ACE #1, 9, 10; p.66-67
Classwork: Today we used a number line, in the context of a relay race, to discover the results of when integers multiply. This is the next logical sequence given that we’ve learned how to add and subtract integers. After looking at a series of problems using running to the right on the number line (positive) and running to the left (negative) in both the future (positive) and past (negative), we were able to draw some conclusions. We looked at multiplication tables and facts and were able to determine the following about multiplying integers: 1) a positive times a negative is a negative & 2) a negative times a negative is a positive. Use this concept when working on your homework.
