Ostrich Llama Count

In Ostrich Llama Count students are given the combined number of heads and legs of ostriches and llamas. Using that information they are asked to explain how Raul and Esteban might have figured out how many ostriches and llamas there were. The key concepts are logical/algebraic reasoning and possibly systems of equations.

This task includes:

  • Problem 
  • Teacher Packet - the teacher packet provides an "answer check" and a range of sample solutions.
  • Primary Rubric 
  • Scenario - the scenario provides a story to help introduce the problem in a way that makes the mathematics as relevant as possible.
