1 00:00:00,380 --> 00:00:04,480 Unplugged Activity | Relay Programming 2 00:00:07,540 --> 00:00:12,100 Hi, I'm Anna! Today we're going to do relay programming. 3 00:00:12,110 --> 00:00:16,470 It's all about programming under pressure and debugging the mistakes that sometimes 4 00:00:16,470 --> 00:00:22,430 happen when you work really quickly or in teams. We'll use graph paper programming to 5 00:00:22,430 --> 00:00:29,430 simulate coding, and use relay races to simulate having a deadline. In relay programming, teams 6 00:00:32,250 --> 00:00:37,660 will be racing to finish a graph paper program. You have to check your teammate's work, or 7 00:00:37,660 --> 00:00:44,660 debug it, fix it if there's a mistake, add your arrow, and run back and tag your teammate. 8 00:00:45,079 --> 00:00:52,079 Programmers use debugging a lot to find and fix problems in their algorithms or code. 9 00:00:56,710 --> 00:01:01,829 There are lots of ways to debug problems. One of the easiest is to move step by step 10 00:01:01,829 --> 00:01:08,149 until you find where something goes wrong, then fix it. Here, I'm trying to do a back 11 00:01:08,149 --> 00:01:15,149 handspring, but I keep falling off. I walk through each part, step by step, and realize 12 00:01:15,479 --> 00:01:22,479 where my mistake was. My coach showed me I wasn't putting my hands on the beam correctly. 13 00:01:23,840 --> 00:01:29,020 So I tried another back handspring on the beam with my new hand position, and I stuck 14 00:01:29,020 --> 00:01:36,020 it! I was really glad I debugged my back handspring. We figured it out! 15 00:01:36,020 --> 00:01:40,120 Debugging is finding and fixing problems. 16 00:01:42,900 --> 00:01:44,900 Nice, Anna! Good job!
