Curated OER
Mechanically Inclined
Eighth graders examine the mechanical advantage of an inclined plane through experimentation.
Curated OER
The Quadratic Formula
Students solve quadratic function by completing the square. In this algebra lesson, students use the quadratic formula to factor quadratics and find the roots. They graph the parabola and identify its properties.
Curated OER
The Play
Students work together to solve word problems. They examine the concepts of functions and relations. They develop plans for roles in the play they are creating.
Curated OER
Jackson's Consecutive Numbers
Students generate patterns from a structured problem, finding a rule for the general term, and expresses it in words and symbols. They then devise and use problem solving strategies to explore situations mathematically.
