WEBVTT 00:00:13.099 --> 00:00:15.910 This lesson is called Tangram Algorithms. 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. 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. 00:00:26.660 --> 00:00:30.710 An algorithm is just a list steps that you can take to complete a task. 00:00:30.710 --> 00:00:34.090 We use them every day with things like shopping lists and recipes. 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 00:00:40.000 --> 00:00:43.570 that algorithm might not get exactly what you wanted. 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 00:00:48.050 --> 00:00:51.469 will need to be detailed and very specific. 00:00:51.469 --> 00:00:54.899 I'm using an algorithm today to complete a painting. 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. 00:01:00.469 --> 00:01:04.409 Luckily for people by me, there is paint by numbers. 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 00:01:12.049 --> 00:01:14.450 each section. 00:01:14.450 --> 00:01:20.049 Paint by numbers tells me exactly what color to use and where. 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. 00:01:25.400 --> 00:01:27.020 It's a great algorithm. 00:01:27.020 --> 00:01:32.640 If the instructions weren't specific enough, my wolves wouldn't look as good. 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 00:01:36.109 --> 00:01:40.870 best to be extremely precise.
