✨ Welcome to Quarter 2: Equations, Inequalities, and Systems
This quarter builds on your algebra foundation with more real-world problem solving. You’ll learn how to:
✏️ Solve and graph inequalities
📊 Interpret and write equations from word problems
🔗 Solve systems of equations (graphically, by substitution, and elimination)
📈 Deepen your understanding of linear functions and slope-intercept form
Each lesson includes:
🎯 Objective – A quick summary of what you’ll learn
🎥 Teacher Video – Direct instruction from one of your teachers
📺 Supplementary Videos – Curated YouTube videos with different teaching styles (visual, fast-paced, contextual)
📝 Practice Activities – Opportunities to try problems and check your understanding
💡 Tips for Success:
▶️ Watch the teacher video first to learn the core idea
👀 Explore extra videos if you need a different explanation
✍️ Do the practice — it’s how you’ll get better and more confident
🙋 Ask your teacher if you get stuck — we’re here to help
These documents support your learning all quarter long. They won’t change from day to day — keep them handy!
