1 00:00:13,099 --> 00:00:15,910 This lesson is called Tangram Algorithms. 2 00:00:15,910 --> 00:00:21,189 A tangram is a puzzle with seven pieces that can be put together to make other shapes. 3 00:00:21,189 --> 00:00:26,660 You'll be using an algorithm to explain to your partner how to put the puzzle together. 4 00:00:26,660 --> 00:00:30,710 An algorithm is just a list steps that you can take to complete a task. 5 00:00:30,710 --> 00:00:34,090 We use them every day with things like shopping lists and recipes. 6 00:00:34,090 --> 00:00:40,000 If you keep an algorithm simple, there are lots of ways to interpret it and whoever performs 7 00:00:40,000 --> 00:00:43,570 that algorithm might not get exactly what you wanted. 8 00:00:43,570 --> 00:00:48,050 If you want to make sure that everyone ends up with the exact same thing, then your algorithm 9 00:00:48,050 --> 00:00:51,469 will need to be detailed and very specific. 10 00:00:51,469 --> 00:00:54,899 I'm using an algorithm today to complete a painting. 11 00:00:54,899 --> 00:01:00,469 I wanted to try doing a painting of some wolves but I'm not the most amazing painter. 12 00:01:00,469 --> 00:01:04,409 Luckily for people by me, there is paint by numbers. 13 00:01:04,409 --> 00:01:12,049 There are forty colors and it has little letters and numbers that tell you which color to paint 14 00:01:12,049 --> 00:01:14,450 each section. 15 00:01:14,450 --> 00:01:20,049 Paint by numbers tells me exactly what color to use and where. 16 00:01:20,049 --> 00:01:25,400 It's very specific so I'm able to follow directions and the painting will come out looking awesome. 17 00:01:25,400 --> 00:01:27,020 It's a great algorithm. 18 00:01:27,020 --> 00:01:32,640 If the instructions weren't specific enough, my wolves wouldn't look as good. 19 00:01:32,640 --> 00:01:36,109 When you really want something to turn out exactly the way that you planned it, it's 20 00:01:36,109 --> 00:01:40,870 best to be extremely precise.
