Elevation Expedition Answer Key

This worksheet uses elevation to help students practice ordering integers from lowest to highest. Each location is described by a height above or below sea level, so students must interpret positive elevations, negative elevations, and zero before ranking all ten places. A location at -140 feet must come before one at -85 feet, while a location at 0 feet sits exactly at sea level, and positive elevations such as 125 feet or 310 feet come later. The activity strengthens integer ordering, positive and negative values, sea-level interpretation, least-to-greatest reasoning, and real-world data skills.

For a parent, this can be explained very simply: sea level is zero. Anything below sea level is negative, and anything above sea level is positive. The farther below sea level a location sits, the smaller its integer value. So -140 feet is lower than -65 feet. Once all the negative locations are ordered, zero comes next, followed by the positive elevations from smallest to largest.

Learning Goals

• Interpret Elevation as Integers: Students use negative values for below sea level and positive values for above sea level.
• Order from Lowest to Highest: Learners arrange all elevations from least to greatest.
• Use Zero as Sea Level: Students understand zero as the reference point separating below and above sea level.
• Compare Negative Elevations: Learners reinforce that -140 is less than -85.
• Apply Integer Skills to Geography: Students connect number order with physical height and depth.

Parent-Friendly Teaching Tips

A useful routine is:

1. Find all the negative elevations first.
2. Put the most negative value first.
3. Place 0 feet after the negatives.
4. Then order the positive elevations from smallest to largest.

For example:

-140 ft, -85 ft, -30 ft, 0 ft, 125 ft, 190 ft

is already arranged from lowest to highest.

Why This Worksheet Helps

• Gives Integers Physical Meaning: Students can picture locations below or above sea level.
• Strengthens Ordering Across Zero: Learners must combine negative, zero, and positive values in one list.
• Builds Geography Connections: Elevation gives students another real-world reason to understand integers.
• Reinforces Least-to-Greatest Order: “Lowest to highest” is a natural-language version of the same mathematical skill.
• Encourages Careful Comparison: Larger digit values do not always mean greater integers when negatives are involved.

Classroom & Home Use

• Great for Math and Geography Connections: Teachers can pair the activity with maps, mountains, or sea-level discussions.
• Easy for Parents to Explain: Ask, “Which location is physically lower?”
• Helpful for Visual Learners: A vertical number line works very well with elevation.
• Useful for Review: The worksheet gives strong mixed practice with positive and negative numbers.
• Good for Homeschool Lessons: Families can extend the activity by looking at real elevations from familiar places.

This worksheet helps students understand that integer order can describe real positions in the world. Below sea level, sea level, above sea level, positive values, negative values, and ordering all come together in a meaningful way. For parents, the simplest idea is: lower elevation means a smaller integer. In classroom and homeschool settings, this activity gives students another practical and memorable way to master comparing and ordering integers.
