Students create a program that will list multiples of a number. The program asks for the number that you want the multiples of.

This Scratch program shows three different ways that students might write the program.

Extension: Have students create a program that finds the LCM of two numbers. See Code with Mr. Dueck website for an example of a LCM Scratch program.

Students create a program that will list the factors of any number.

This Scratch program shows two different functions that could be used when writing the program. Each sprite represents a different program.

Extension: Have students write a program that finds the GCF of two numbers. See Code with Mr. Dueck website for an example of a GCF Scratch program.

Students could create programs to list prime numbers or determine if a number is prime or composite (Dueck, 2021). See Code with Mr. Dueck website for examples of these Scratch programs.
