Reflection: Cycles of Inquiry Those Negative Numbers - Section 1: Launch


Despite having models to explain addition and subtraction of signed numbers, my experience in teaching my students is that many struggle more  with understanding subtraction with integers, than multiplication with integers. Despite this recognition on my part, I still find it a difficult topic to teach. I've never been fully satisfied with student outcomes after teaching integers, and, I have tried multiple approaches. Unfortunately, too many students carry weaknesses in this area far past middle school, which is one of the reasons I include this review lesson for 7.NS.A.1 in my Grade 8 class.

I personally think that students need much time and support in their earlier years, starting at the lower elementary level,  to conceptualize negative numbers, so that by the time they reach middle school, performing operations with signed numbers is grasped more easily and of course, fully understood.

If you have thoughts or lessons that work for you, I would love to hear from you. I continue to look for and try new ideas.
