## Reflection: Connection to Prior Knowledge Multiplying and Dividing Rational Numbers - Section 1: Launch

For my openers, I try to continually spiral in previous material, so that information is not lost or forgotten.  For this opener, the first two problems are unit rate problems - the second one
contains the word "per" and is more obviously a unit rate problem. Students were able to easily solve the second problem, but struggled a bit with the first.  Not only did the first problem not contain the word per, but it required students to compare paint to walls, not walls to paint as the order of delivery of facts in the problem might suggest.  Proportional reasoning is a major work of the 7th grade, and we spent an entire nine weeks on that strand of the common core - I will certainly continue to practice PR questions during opener time, and I will make sure that not all questions are obvious in what they are asking.
