This presentation is a great way to teach students how to add and subtract positive and negative integers in 7th grade. It directly correlates to standard [7-NS1] and [7-NS3] in the Common Core. This concept is frequently reviewed at the beginning of 8th grade because of its importance in mastering other standards. This lesson is designed to get students involved through questioning. The answers to each example are provided at the end of the PowerPoint. It can be easily converted into a Flip Book for Smart Board users. I use the PowerPoint on my Smart Board as it is.
Included is a worksheet with answers that may be used for a homework or classwork follow-up activity. It is a 20 question worksheet that includes computation questions, an error analysis question, and a word problem.
