Programming 4 Kids in Scratch 2: (Advanced) Challenge #59 - Recursive Sum

Welcome to Programming 4 Kids with Scratch 2.

This is the 59th of over 60 challenges to teach kids (about 5th grade and up) programming using Scratch 2.

This advanced challenge introduces recursion with a recursive program to add a series of numbers.

Recursion solves a problem by breaking the problem up into smaller (and smaller, ...) problems and using itself to solve them all. This is a great opportunity to try to understand recursion before encountering problems with recursive solutions later.

Challenges build upon earlier challenges so I recommend viewing all of the challenges in order. Feel free to browse around and watch what interests you. If you find a challenge too hard try going back to earlier challenges to build your foundation.

The last challenge shows children they're ready to program in other languages (Java, C++, C, Python, JavaScript) with a challenge comparing blocks of Scratch with block of code from other languages.

Comment policy:

I’ll try to answer your questions when I can.

Positive and constructive negative feedback is always welcome.

Since the videos are aimed at children I will remove comments that I deem to be inappropriate for children.
