Teach-Back: Core Concepts
You and your partner are going to take turns teaching each concept below. One person opens a section and explains the concept in their own words. Then you both look at the code and walk through it line by line together.
How it works: Open a section. Read the prompt. Try to explain it without peeking. When you're ready, reveal the definition, then the code. Walk through every line out loud. Then your partner takes the next one.
