Lesson objective: Add and subtract fractions in a word problem.
This lesson provides an opportunity for students to apply their knowledge and understanding of fraction addition and subtraction to a real-life situation.

The distance of one segment of the course is not revealed, so students must use addition and subtraction strategies to accurately model it.

(Model with mathematics) by using a description to create a model of a real-world situation, and then using that model to answer question about the situation. The number line is especially important in this lesson as students use it to show the distance between the obstacles.
