Lesson objective: Solve problems by ordering and comparing integers based on their distance and direction from zero.

This lesson provides an opportunity for students to apply their knowledge and understanding of integers to a real-life situation. Students are asked to determine the locations of frogs using details from Robbie's notes.

Key Concept students will use:

• There are three possible relationships between any two numbers, a and b (namely a < b, a > b, and a = b) for the set of integers.

Skills students will use:

• Plotting points on a number line
• Interpret and reason with mathematical language

Students engage in Mathematical Practice 1(Make Sense of Problems and Persevere in Solving Them) as they use their knowledge of integers on the number line to determine the location of the frogs.

Key vocabulary:

• Above sea level
• Below sea level
• Depth
• Greater than
• Integer
• Less than
