Description
Bring fun to your math lessons with this engaging, story-driven word problem activity. The National Park Perimeter Challenge helps students strengthen their measurement and problem-solving skills by finding missing sides using perimeter in an exciting national park setting. Each task card follows a park ranger, volunteer, or visitor working in the national park - marking out trails, setting up campsites, and building new spaces - while solving a real-world math problem. As they solve each problem correctly, they unlock parts of a coordinate grid. Once all problems are complete, they use the coordinate plane code to reveal a final mystery phrase. These self-grading Boom Cards are perfect for Grade 4-6 students. Use them for math centers, review, early finishers, or independent practice. What's Included ✔ 1 Boom Deck (13 self-grading digital task cards) ✔ Real-world national park themed perimeter word problems ✔ Engaging story-driven scenarios set in a national park ✔ Coordinate plane mystery phrase reveal activity ✔ Students solve, unlock grid sections, and follow the code to reveal the phrase This deck reinforces • Finding the missing side of a rectangle using perimeter • Applying a three-step problem solving method • Working backwards from a known perimeter to find an unknown side • Reading and applying coordinate plane codes • Strengthening reasoning, accuracy, and spatial thinking
