Understanding Temperature and Its Scales

Ms. Hugley introduces sixth graders to rational numbers, focusing on positive and negative numbers. The lesson includes learning targets, vocabulary, and activities like 'Notice and Wonder' and 'Above and Below Zero' to explore temperature changes using number lines. Students engage in discussions and practice problems to understand the concepts of positive and negative numbers, with a check for understanding to assess their grasp of the material.
