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

0:00:12.110,0:00:16.470
It's all about programming under pressure[br]and debugging the mistakes that sometimes

0:00:16.470,0:00:22.430
happen when you work really quickly or in[br]teams. We'll use graph paper programming to

0:00:22.430,0:00:29.430
simulate coding, and use relay races to simulate[br]having a deadline. In relay programming, teams

0:00:32.250,0:00:37.660
will be racing to finish a graph paper program.[br]You have to check your teammate's work, or

0:00:37.660,0:00:44.660
debug it, fix it if there's a mistake, add[br]your arrow, and run back and tag your teammate.

0:00:45.079,0:00:52.079
Programmers use debugging a lot to find and[br]fix problems in their algorithms or code.

0:00:56.710,0:01:01.829
There are lots of ways to debug problems.[br]One of the easiest is to move step by step

0:01:01.829,0:01:08.149
until you find where something goes wrong,[br]then fix it. Here, I'm trying to do a back

0:01:08.149,0:01:15.149
handspring, but I keep falling off. I walk[br]through each part, step by step, and realize

0:01:15.479,0:01:22.479
where my mistake was. My coach showed me I[br]wasn't putting my hands on the beam correctly.

0:01:23.840,0:01:29.020
So I tried another back handspring on the[br]beam with my new hand position, and I stuck

0:01:29.020,0:01:36.020
it! I was really glad I debugged my back handspring.[br]We figured it out!

0:01:36.020,0:01:40.120
Debugging is finding and fixing problems.

Nice, Anna! Good job!
