Inequalities I
Classroom manga, quiz, Boundary Runner, and inequality labs.
Use → / Space to advance, ← to go back. Each slide builds the idea step by step.
Swipe left for next slide, right for previous — or use the arrows. Each slide builds the idea step by step.
Tap the ← and → buttons below the slide. Each slide builds the idea step by step.
Difficulty rises: 3 positive → 5 negative (sign flip) → 4 multi-step. In Stage 3, enter the boundary value, then drag the sign and hollow / filled.
Read each page. When a concept finishes, answer the two follow-up questions. They stay on this tab only.
Boundary Runner
Run the platforms, then solve the inequality to open the next gate.
Match each inequality (x≥0, x>0, x≤0, x<0) to its number-line picture — filled dot = “or equal”, hollow dot = strict.
You mastered sign flips across all three stages!
- Flipping the sign when × or ÷ by a negative
- Fraction gates — division flips the inequality too
- Multi-step problems with hidden negatives at the end
Keep it up — you’ve got this! 💪
🏕 Safe Camp
Checkpoint reached! Progress saved.
Choose one power-up for the road ahead:
No Lives Left!
The chained doors were too dangerous. Remember to flip the sign when × or ÷ by a negative!
Doors cleared: 0 / 15
Three stages of 5 doors. Rest at safe camps after doors 5 & 10!
Stage 1: basic negatives • Stage 2: fraction gates • Stage 3: multi-step traps. Keys: A B C D.
