Strategies for Solving Word Problems with Rational Numbers

This video tutorial teaches how to solve word problems using rational numbers by identifying keywords, writing equations, and creating models. It reviews integers and rational numbers, demonstrating their representation with number lines and chips. The tutorial provides examples, including a submarine's depth change, a football team's yardage, and a bird catching a fish, illustrating strategies like highlighting keywords and using equations and models to find solutions.
