Algebraic Expressions

Problem-based Digital Making Tasks

  1. Is 7081 a prime or composite number?  
  2. Make a prime or composite detector.  

How CT may Support Mathematics Learning

The use of conditionals and Boolean operators will come into play when checking whether a number is prime or composite. In particular, students will need to loop a function to check the divisibility of a given number by checking possible factors between 2 to (dividend – 1).
