Learning experience for MYP Year 1 that we did in class today to identify and visualize composite numbers as a product of prime factors. Students made a number trail using building blocks through which they were able to identify the prime factors of numbers up to 20. The composite numbers will have the same colors as their prime factors. Students were able to visually see that prime numbers are only divisible by themselves (each being a lone cube) and that composite numbers are simply composed of primes (multiple cubes). Each child in the class was engaged and participative.
Extended question: Why is 1 neither prime nor composite.
