How to Play the Game

1. Read the Problem: Examine the prompt in the problem box. This may include a conceptual question, a functional equation, a word problem, or an x/y data table.
   
2. Select Your Answer: Click one of the multiple-choice option buttons that correctly identifies the growth model, calculates the rate of change, or selects the matching function.
   
3. Review Feedback & Solutions: Upon selecting an option, instant color-coded feedback will reveal whether your choice was correct. A detailed solution guide will display to break down the step-by-step math.
   
4. Track Your Score: Watch your real-time score and current question counter in the top bar as you advance through the 10-question lab.
   
5. Complete the Run: Work through all 10 randomized questions to reach the summary screen and check your final percentage accuracy.

Educational Summary
The Linear vs. Exponential Game reinforces critical high school Algebra 1 concepts by challenging students to differentiate between additive (linear) and multiplicative (exponential) relationships.

Through conceptual prompts, tabular analysis, and real-world scenarios, students learn to recognize that linear functions grow by equal differences over equal intervals (y = mx + b), whereas exponential functions grow by equal factors/ratios over equal intervals (y = a &middot b^x). Furthermore, the game highlights the fundamental principle that exponential growth functions with a base b > 1 will eventually surpass any linear function over a sufficiently large domain, regardless of the linear function’s starting value or slope.

Teacher’s Guide & Classroom Integration
Target Audience: Grades 8–10 (Algebra 1, Integrated Math I)
Standards Alignment: CCSS.MATH.CONTENT.HSF-LE.A.1 (Distinguish between situations that can be modeled with linear functions and with exponential functions), CCSS.MATH.CONTENT.HSF-LE.A.2, CCSS.MATH.CONTENT.HSF-LE.A.3. Recommended Usage:
Warm-Up / Bell Ringer: Use as a 5-minute warm-up activity to activate prior knowledge before introducing logarithmic or advanced function units.
Formative Assessment: Have students complete a run individually and screenshot their final percentage score for a quick check-for-understanding grade.
Pair Competition: Place students in pairs to compete for the highest score or fastest completion time while discussing the solution guide explanations together.
