This 37-page differentiated multi-day quadratic modeling lab engages students in building a quadratic function from the product of two linear relationships. Students model revenue (and profit at advanced levels), determine maximum values, interpret intercepts, and evaluate reasonableness within context. Rather than simply solving a quadratic, students construct — developing deep structural understanding of why multiplying two linear functions produces a quadratic model. 3 Differentiated Levels

🎄 Bring festive fun and meaningful rigor to your Algebra classroom with this Christmas Graphing Activity, where students create a Christmas tree using equations and restricted domains. Students graph a Christmas tree using linear equations with restricted domains, carefully connecting multiple line segments to form a complete image. With four differentiated versions included, this activity is perfect for meeting the needs of diverse learners and for use across Algebra I and Algebra II courses.

Start the school year with a powerful math and SEL activity that helps students express their identities through numbers and expressions! This Back to School Math About Me Project— Me in Math—engages students in meaningful self-reflection while reviewing key math skills like expressions and order of operations as students create expressions that equal a number about them. Perfect for upper elementary, middle school, Algebra 1, or any math class, this flexible, no-prep resource supports comm
