How to Play the Game

1. Choose Your Level: Select your challenge mode from the header dropdown (Level 1: Same Area, Level 2: Same Perimeter, or Level 3: Master Architect).
   
2. Read the Blueprint Prompt: Review the target area (A = w × h) or perimeter (P = 2w + 2h) requirements in the top card.
   
3. Solve the Challenge:
   Build Mode: Use the width and height spin buttons (+ / -) to dynamically resize your rectangle on the grid until the live stats match the prompt, then click Check Blueprint.
   Compare Mode: Examine Rectangle A and Rectangle B on the side-by-side grid, read the comparison question, and click the matching multiple-choice answer.
   
4. Build Your Streak: Complete consecutive correct blueprints to earn points and build your answer streak.

Educational Summary
Rectangle Remodel targets Common Core Standard 3.MD.D.8 (solving real-world and mathematical problems involving perimeters of polygons, including finding the perimeter given side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters).

The game transitions students from passive formula memorization to spatial reasoning. By adjusting dimensions dynamically on a grid visualizer, learners visually observe two key geometric principles:

• Rectangles with identical area can have drastically different perimeters (elongated, skinny rectangles yield larger perimeters).
• Rectangles with identical perimeters can enclose varying amounts of space (equilateral/square-like shapes maximize internal area).

Teacher’s Guide
Learning Objectives
Construct rectangles with specific area and perimeter values using grid units.
Differentiate conceptually between boundary length (perimeter) and surface enclosure (area).
Predict how changing width and height affects perimeter while holding area constant (and vice-versa).

Lesson Integration Strategies
Whole-Class Discovery Warm-Up (10 Mins): Project the game on Level 1. Ask the class: “If we need an area of 12, how many different rectangles can we make?” Have volunteers test different dimension pairs (e.g., 6 × 2 vs 4 × 3) and compare their resulting perimeters before submitting.
Small-Group Math Center (15 Mins): Have students work in pairs on Level 3. Partner A predicts the shape dimensions, and Partner B builds it on screen. Require students to write down the formula calculations on whiteboards before pressing Check Blueprint.
