Distance and Position in Math

This video introduces seventh graders to rational number arithmetic, focusing on interpreting negative numbers. The lesson includes activities using thermometers to understand number lines and temperatures, as well as exercises comparing vertical positions of animals relative to sea level. Students are guided through a rational number card sort activity, arranging integers, fractions, and decimals from least to greatest. The video emphasizes the importance of visual aids and provides opportunities for extra credit through challenging questions.
