Absolute Value and Temperature Concepts

This video tutorial covers Math 6 Unit 7 Lesson 7, focusing on comparing numbers and distances from zero using absolute values and negative numbers. The lesson includes activities on plotting rational numbers on a number line and comparing elevations relative to sea level. Students engage in exercises to understand the concept of opposites and absolute values, and they complete a table based on elevation comparisons. The lesson concludes with a summary and homework instructions.
