Instructional Ideas
  • Assign for homework or independent extra credit on Valentine's Day
  • Use as a Valentine's Day activity in trigonometry class
  • Give extra points to students whose hearts are the smoothest
  • Divide the class into three sections, and have each section try one strategy before moving on to the next one; have class members reflect on which technique was easiest for them and which one worked the best
Classroom Considerations
  • Provides a small grid to graph equations, but students may work better on a larger piece of graph paper
  • All equations are linked at the bottom of the page
  • Encourages critical thinking and problem solving
  • Designed for high school Common Core standards
  • None
