This PowerPoint Presentation (created in PowerPoint 2013) follows along with the Eureka Math/Engage NY sixth grade Module 2 Topic D. These four lessons delve into number theory - thinking logically about multiplicative arithmetic. You will find that these presentations will practically eliminate your planning time - except to review the slides of course! You will be able to focus on your students - not on how are you going to teach this topic using a document camera. There are enough colors, animations, and surprises to keep the most jaded sixth grader engaged! I have added Bell Ringers taken from the released questions from the 2015 New York state test. I hope you find my slides helpful. Be sure you have Microsoft Office 2013 - 2009 will work but the animations will be wonky and the spacing will be off. I will be putting up the rest of the sixth grade work - keep checking back!
