Freebie! A lesson on the distance of two integers

Hot off the presses! I wanted to share this 7th grade lesson on the distance of two integers that I recently wrote for the upcoming Math Mammoth grade 7.

I'd be interested in feedback, as well!



It is written specifically to match the Common Core Standard 7.NS.1 (c)

Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.

In easier terms... the lesson deals mostly with integers, and teaches that the distance of two integers m and n can be found by taking the absolute value of their difference: |mn|.

Download the lesson here (a PDF file). There is no answer key at the moment -- sorry about that!
