Real World Math: Concept Lessons - Oil Spill Estimates
Real World Math

Unfortunately, real world math lessons are sometimes learned from tragedy. 

Illuminations: Rates of Change in Pick’s Theorem
Illuminations (National Council of Teachers of Mathematics)

Students will use a spreadsheet to investigate rates of change among various figures created on a geoboard.

Illuminations: Pick’s Theorem as a System of Equations
Illuminations (National Council of Teachers of Mathematics)

Students will gather three examples from a geoboard or other representation to generate a system of equations.

Illuminations: Rediscovering the Patterns in Pick’s Theorem
Illuminations (National Council of Teachers of Mathematics)

Students will use a geoboard, geoboard interactive, or Geometer’s Sketchpad® to help them discover the pattern of Pick’s Theorem.
