I want to come talk to you during this time!

• If your team is unsure about something and I’m not talking with another group, flag me down by raising your hand.
• If I am talking with another team, use the Team Exercise Help Table to write your team number next to the Exercise you want to talk about.
• I’ll use this as a queue of teams to go talk to, and also to tell if there’s something worth discussing as a whole class.

Discussion: Pseudocode

3. Write pseudocode for a program that repeatedly prompts a user for non-negative integers; once the user inputs a negative number, the program ends and outputs the sum of the input positive integers.

Pseudocode does not come naturally to many beginning students! Let’s look at a few solutions and talk it over a little.

Programs of the Day - Introduction / Demo

Demo: download the POTD skeleton and tests, and run the program and the tests in Thonny.

See the POTD Guide, which also explains this process.
