Algebra: Chess - The King

Australian curriculum number (ACMNA073; ACMNA083)

Students build their algebraic reasoning and understanding of number as they explore computation on the number chart. The key understandings of symmetry, equivalence and compensation are developed through algebraic generalisation.

This sequence is for students who:

  • can add two-digit numbers.
  • are familiar with using the number chart as a tool for exploring patterns. 


Lesson 1: The King

In this task, the king has escaped from a regular chessboard onto a hundreds chart. The students explore the moves of the king and the ways in which the value of the numbers change as he moves. This builds into an algebraic exploration of equivalent values that can be found on the number chart.
