Ganges River Dolphins Do Geometry

Ganges River Dolphins Do Geometry


Ganges river dolphins can only live in freshwater and are essentially blind. They hunt with ultrasonic sounds, which bounce off of fish and other prey. In order to find their prey, they must know geometry very well. Can you help them out?


Through in-class activities and independent practice, students will:

  • Enter radii with angle measurements and explore vertical angles
  • Use a Cartesian coordinate grid to locate points and measure distances between points
  • Create symmetrical shapes on a coordinate grid using a line of symmetry
  • Represent linear relationships by translating x-y tables to graphs and translating graphs to x-y tables
  • Locate points expressed as fractions and decimals to the tenths place by scaling the Cartesian coordinate plane

        *There is an additional $45 charge for DreamBox, which is a one-time purchase for the entire school year. Here at The Thinking Kid, we utilize the DreamBox Math App to enable our students to practice math skills outside of the classroom. DreamBox engages students through math games to test their proficiency in math concepts discussed in class. DreamBox access is essential to student success in our math program.
