What it practices

• 7.NS.A.1: adding and subtracting integers on a vertical number line, and subtracting as adding the opposite
• 7.NS.A.2: sign rules for multiplying and dividing (Express Elevator)
• 6.NS.C.5–6: positive and negative numbers as positions above and below zero

Use it in class

• Warm-up: project Ground Floor and let students call out floors.
• Class vs. teacher: you play, they shout corrections before the doors open.
• Exit ticket: students pick one rider from their review and explain the move in words.
• Whiteboard: students can sketch their own number line or jumps before they tap a floor.

Why it clicks

A wrong answer isn't a red X. The elevator goes back to the start and rides the move one floor at a time, so students see where 3 + (−7) lands and why. Every miss can be replayed again from the results screen.

What it practices

• 7.NS.A.1: adding and subtracting integers, including subtracting negatives
• 7.NS.A.2: sign rules for multiplying and dividing

Use it in class

• Brain break with math: Chill speed works for every student. Hype is for your speed demons.
• Error hunt: each question has a sign-flip trap door. Ask why it's tempting.
• Exit ticket: pick a missed question from the review and explain the fix.

Why it clicks

The wrong doors aren't random. One is always the sign-flip answer, and the others are the classic slip-ups, so students practice catching their own mistakes.

What it practices

• 6.NS.C.6b: what the signs of a point's coordinates say about its quadrant
• 6.NS.C.6c & 6.NS.C.8: plotting and reading points in all four quadrants, and moving left, right, up and down on the grid
• Axes and the origin: points with a 0 coordinate, and the classic "x first, then y" mix-up

Use it in class

• Warm-up: project one flight and let the class call out each course.
• Independent practice: students fly solo on their own devices. A mission takes about 5 minutes.
• Exit ticket: "Write the coordinates of every stop your ship made, in order."

Why it clicks

Every right answer moves the ship, so students see exactly where their coordinates point. Wrong answers get a hint first and the full steps second, so students fix the mistake themselves.

What it practices

• 5.NF.A.1: adding and subtracting fractions with unlike denominators
• 5.NF.A.2: answers greater than 1, as improper fractions or mixed numbers

How it ramps

• Warm-up (gates 1–3): one denominator is a multiple of the other, like ½ + ¼
• Getting there (4–6): unrelated denominators, like ⅔ − ¼
• Challenge (7–10): bigger denominators and sums greater than 1

Why it clicks

The running and jumping keep students moving between problems, and every bridge is labeled with the answer that built it. Two tries per gate, then the steps are shown so nobody gets stuck.
