Aim: How can we practice using the addition and subtraction algorithm of rational numbers?
Homework: No HW
1. -10 - (-12) = 2. -2.5 + (-5.7) =
Classwork: We explored subtraction problems with integers and understood this central point: subtracting a negative is the same as adding a positive AND subtracting a positive is the same thing as adding a negative.
Announcements: There will be a quiz next week, tentatively Wednesday 10/4/17
