How to Play the Game

1. Read the Scenario: Read the real-world scenario displayed in the top text box to identify the two inversely proportional variables.
   
2. Analyze the Data: Examine the numerical values in the middle box to find the initial conditions and the target variable.
   
3. Calculate the Answer: Use the inverse variation formula (\(y = \frac{k}{x}\) or k = xy) to solve for the constant of variation (k), then find the required unknown value.
   
4. Select Your Answer: Choose one of the four multiple-choice options.
   
5. Review Feedback:
   If correct, you will hear a high-pitched chime and earn a point.
   If incorrect, read the Step-by-Step Solution guide that appears automatically to trace where your calculation went wrong.
   
6. Advance: Click Next Question to proceed through the 10-question set.

Educational Summary
Inverse Variation Solver is an interactive educational tool tailored for Grade 9 math students learning to analyze, model, and solve problems involving inversely proportional relationships.

Learning Objectives
Recognize inverse relationships in physical and real-world contexts (e.g., speed vs. travel time, number of workers vs. job completion time, pressure vs. volume).
Calculate the constant of variation (k = xy) using given starting conditions.
Formulate inverse variation equations (\(y = \frac{k}{x}\)) to represent mathematical relationships.
Apply the inverse variation model to compute missing values when one variable changes.

Features
Dual-Box Problem Layout: Separates qualitative context from numerical data, helping students distinguish structural relationship setup from numerical evaluation.
Immediate Remediation: Displays an explicit 3-step solution process (Find k → Write equation → Substitute and solve) following every student answer.

Teacher’s Guide & Classroom Integration
Recommended Grade Level
Grade 8–9 (Pre-Algebra / Algebra 1)

Curriculum Alignment
CCSS.MATH.CONTENT.HSA.CED.A.2: Create equations in two or more variables to represent relationships between quantities.
CCSS.MATH.CONTENT.HSF.IF.C.7: Graph functions expressed symbolically and show key features of the graph.

Differentiation Strategies
Support: Provide students with a reference card listing common inverse variation formulas (k = xy, \(y = \frac{k}{x}\), and x₁ y₁ = x₂ y₂).
Extension: Ask advanced students to plot the coordinates from 2–3 game problems on graph paper to visualize the hyperbolic shape of inverse variation graphs.
