Year 9: Highly Composite ACT 4

by Texas Instruments

Objectives

This activity covers multiple objectives including improved number sense, pseudo-coding, coding, algorithmic thinking, problem solving and investigations. Students also see the power in representing numbers in different forms, including as a product of its prime factors. Students need to pose and test hypothesis as they work towards being able to predict subsequent highly composite numbers. They can improve their coding algorithms to the point of creating a level of AI within their coding.

  • Algorithm

Coding

  • def function
  • if
  • for
  • % (Modular Arithmetic)
  • while

About the Lesson

This activity is Part 4 of the series Code by Numbers. This activity requires students to turn explore Highly Composite Numbers. On the surface it is hard to see the patterns, however, change the representation of the number to its prime factorisation and the patterns start to emerge. Don't make too many assumptions however as some of the patterns disappear when you least expect it. Mathematicians are still exploring HCN's, so this activity is a genuine mathematical investigation that incorporates coding, logic, reasoning, hypothesis posing and testing and much more.
