Unplugged - Relay Programming

Unplugged Activity | Relay Programming

Hi, I'm Anna! Today we're going to do relay programming.

It's all about programming under pressure
and debugging the mistakes that sometimes

happen when you work really quickly or in
teams. We'll use graph paper programming to

simulate coding, and use relay races to simulate
having a deadline. In relay programming, teams

will be racing to finish a graph paper program.
You have to check your teammate's work, or

debug it, fix it if there's a mistake, add
your arrow, and run back and tag your teammate.

Programmers use debugging a lot to find and
fix problems in their algorithms or code.

There are lots of ways to debug problems.
One of the easiest is to move step by step

until you find where something goes wrong,
then fix it. Here, I'm trying to do a back

handspring, but I keep falling off. I walk
through each part, step by step, and realize

where my mistake was. My coach showed me I
wasn't putting my hands on the beam correctly.

So I tried another back handspring on the
beam with my new hand position, and I stuck

it! I was really glad I debugged my back handspring.
We figured it out!

Debugging is finding and fixing problems.

Nice, Anna! Good job!
