Teach your Algebra 2 students how to analyze R² values, compare regression models, and make predictions with this fully editable lesson and homework set. This is Part 2 of a 3-part Regression Unit, and includes editable notes, TI-84/Excel/Google Sheets instructions, and an assignment with keys for all three platforms so you can teach regression with any classroom technology.

What’s Included

• Editable Guided Notes (Blank Student Version)
• Keyed Guided Notes / 504-Friendly Version
• Homework Assignment (Editable)
• Homework Answer Keys (TI-84, Excel, and Sheets compatible)
• TI-84, Excel, and Google Sheets Instruction Sheets
• Worked Examples with Clear, Organized Layouts

Everything is ready to teach—no extra prep required.

Topics Covered

Students learn how to:

• Generate various regression models (linear, quadratic, cubic, exponential, power, logarithmic)
• Interpret and compare coefficients of determination (R²)
• Choose the best model for a data set
• Make predictions using the chosen model
• Apply modeling skills to real data sets (projectile motion, population growth, etc.)

Aligned to TEKS A2.8A–C and CCSS HSS-ID standards.

Technology-Friendly

Includes fully detailed instructions for:

• TI-84+ graphing calculators
• Microsoft Excel
• Google Sheets

Students can create scatterplots, run regressions, and view equations and R² values using whatever technology your school supports.
