Using algebraic thinking and data analysis, students will conduct mathematics investigations and use the engineering design process to solve real-world problems (environmental hazards, survival, and extreme weather) they encounter in book. The teacher-tested, research-based activities enforce critical thinking skills, teamwork, and problem solving while addressing Texas Essential Knowledge & Skills (TEKS) Standards and ITEA standards. Supports STEM Education. Includes TEKS correlations, rubrics and assessment ideas, a CD-ROM with PDFs of all content from the book, a DVD-ROM with videos of classroom implementation and an Engineering Design Process poster. MP2,3,6 Math Challenges: 1. Define the problem 2. Conduct research 3. Brainstorm solutions 4. Choose a solution 5. Build a model 6. Test & evaluate 7. Communicate 8. Redesign as needed'
