The Problem with Traditional Geometry Instruction
Area and perimeter seem simple on the surface. Length times width. Add up all the sides. But research shows that students who learn these concepts through formulas alone develop deep misconceptions that follow them into middle school, high school, and beyond.
Here's what typically happens: Students memorize "A = l × w" and can plug in numbers. They pass the test. But ask them to actually tile a floor, design a garden, or explain why the formula works, and they're lost. They've learned procedures without understanding.
The consequences show up years later when these same students struggle with fractions, algebraic reasoning, and spatial thinking. They never built the foundation - they just memorized the shortcuts.
What if there was a better way?
Welcome to PRISM Pet Supply: Where Math Becomes Real
In PRISM Pet Supply, students don't just learn about area and perimeter - they use these concepts to design and build an actual pet store. They're not doing worksheets. They're solving real problems that matter.
Students become product designers for PRISM, an innovative pet supply company opening a new superstore. Over 10 engaging sessions, they make critical decisions: Where should the store be located? How big should the parking lot be? What should the signs look like? How do we display products efficiently?
Every decision requires mathematical thinking. Every solution builds deep understanding.
Students design floor plans for the new PRISM superstore, discovering area through purposeful work
One Complete Project. Ten Engaging Sessions.
PRISM Pet Supply isn't a collection of disconnected lessons. It's one immersive project where each session builds on the last, creating a coherent mathematical journey from start to finish.
Students don't just learn area - they discover why area matters when designing play zones for pets. They don't just calculate perimeter - they figure out how much fencing they need for the parking lot. Every concept has a purpose. Every calculation has a consequence.
Mathematical Concepts Covered in PRISM
- • Counting Unit Squares
- • Area Through Tiling
- • Area Through Multiplication
- • Perimeter Measurement
- • Relationship Between Area & Perimeter
- • Arrays & Multiplication
- • Data Collection & Bar Graphs
Why these concepts matter: Area, perimeter, and multiplication form the foundation for fractions, algebraic reasoning, and all future geometry. Students who truly understand these concepts are prepared for mathematical success.
Session 1: Make a Blueprint
Students create unit-square name cards and design a floor plan for the new PRISM superstore. They discover that counting squares is the foundation of area - not just a formula, but an actual understanding of what area means.
Counting unit squares builds genuine understanding of what area means
Session 2: Choose a Location
Where should PRISM build its new store? Students measure distances to various landmarks, collect data, and create bar graphs to analyze their findings. They vote on the best location based on evidence - learning that math helps us make better decisions.
Real measurement, real data, real decisions
Session 3: Pet Play Zones
The new store needs play areas for pets! Students use squares to figure out how many units need to be covered and calculate costs. They discover the connection between counting squares and multiplication - seeing why the area formula actually works.
Session 4: Design a Parking Lot
PRISM needs parking for customers! Students design parking lots with specific requirements, discovering the fascinating relationship between perimeter and area. Same perimeter, different areas. Same area, different perimeters. This exploration builds mathematical intuition that lasts.
Discovering the relationship between perimeter and area through design challenges
Session 5: Order Pet Food
Students measure shelving and figure out how many boxes of each kind of pet food PRISM needs to order. They connect area with tiling to area with multiplication, building fluency with both approaches.
Session 6: Table Displays
Students build table displays using craft sticks and small cubes, exploring arrays and multiplication in a concrete, hands-on way. They see how rows and columns create structure - the foundation for understanding multiplication facts.
Building arrays with physical materials develops multiplication understanding
Session 7: Fish Castles
Team members design a new PRISM product: fish castles for aquariums! With a budget of $10, students decide which materials to use and how to construct their design. They practice addition, subtraction, and multiplication in a creative context that feels like play.
Designing fish castles on a budget - creativity meets mathematical thinking
Every design decision involves mathematical reasoning
Session 8: Signs
PRISM departments each need colorful signs. Students design promotional displays with constraints on both area and perimeter, applying everything they've learned about these concepts in a creative challenge.
Design challenges with mathematical constraints build deep understanding
Session 9: The Commercial
Teams write and present a short television commercial to promote their department's featured pet food. This session integrates communication skills with mathematical content, helping students articulate their understanding.
Session 10: Grand Opening
It's time to open the store... but the dogs have gone missing! Students use their mathematical skills to decode puzzle clues and find the dogs. This capstone session reviews perimeter, area, and arrays in an exciting problem-solving adventure.

Why $149 Is An Investment, Not An Expense
Let's talk about what effective math instruction actually costs:
The Real Cost of Math Struggles
Private tutoring: $40-60/hour × 10 sessions = $400-600
Often focused on re-teaching concepts that should have been understood the first time.
Math enrichment programs: $200-500 per month
Many focus on practice, not understanding.
Supplemental curriculum materials: $50-150 for workbooks
More of the same approach that didn't work initially.
Long-term gaps in understanding: Priceless
Students who don't understand area and perimeter struggle with fractions, algebra, and beyond.
Plus students who actually understand math
Here's what makes PRISM different: You're not buying more practice problems. You're investing in a completely different approach - one where students discover mathematical concepts through meaningful work that they'll remember.

Frequently Asked Questions
How long does PRISM Pet Supply take to complete?
Plan for 15-20 hours of instruction across 10 sessions. Most classrooms complete it in 3-4 weeks meeting 2-3 times per week. Homeschool families often complete it in 2-3 weeks with more flexible scheduling.
What grade levels is this for?
PRISM Pet Supply is designed for grades 3-5. Third graders exploring area and perimeter for the first time will find it appropriately challenging. Fourth and fifth graders who need to build stronger foundations will benefit from the hands-on approach.
Can I use this if I'm not a math teacher?
Absolutely. The embedded teacher guides walk you through every step. You don't need specialized training - just follow the slides, facilitate the activities, and ask the questions provided. Many homeschool parents successfully use PRISM.
How many students can use one kit?
Each kit supports up to 4 students working together as a team. For larger groups, you'll need additional kits.
What if my students already know area and perimeter formulas?
Knowing formulas isn't the same as understanding concepts. Many students who can recite "length times width" cannot explain why it works or apply it flexibly. PRISM builds the deep understanding that makes formulas meaningful.
Can I see a sample lesson before buying?
Yes! Lessons 1-3 are available FREE with a Teacher & Family Account. You'll see the instructional slides, activities, and progression before committing to the full kit.
What if my district wants to purchase multiple kits?
