What does this code do? Hand tracing techniques for iteration and recursion (video)

When faced with "What does this code do?" or "How many times does this loop run?" types of questions, students try to picture a solution in their heads. But it's often more effective to put pencil to paper and do some hand-tracing.

At our recent PD Day, Lisa presented strategies that give students an easy path to success when tackling iterative and recursive methods.

Here's video of her session: 

You can find the resources from this session in a Coding Rooms course called "PD Day 2022," available in our Marketplace.
