Understanding Opposites and Rational Numbers

Ms. Hughley presents a sixth-grade math lesson focusing on positive and negative numbers, plotting points on a number line, and understanding rational numbers and their opposites. The lesson includes activities such as solving a problem of the day, reading temperatures on thermometers, and identifying opposites on a number line. Students are encouraged to actively participate and check their understanding throughout the lesson.
