✨ Welcome to Quarter 4: Systems, Inequalities, and Data
In this final quarter, you’ll apply your algebra skills to real-world situations, combining equations, analyzing inequalities, and making sense of data. You’ll learn how to:
🔗 Solve systems of equations using graphing, substitution, and elimination
🚦 Represent and solve inequalities on number lines and coordinate planes
📊 Interpret data and use statistics to describe and make predictions
📉 Understand when a model is linear, exponential, or neither — and how to choose the best one
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!
