0:00:13.099,0:00:15.910 This lesson is called Tangram Algorithms. 0:00:15.910,0:00:21.189 A tangram is a puzzle with seven pieces that[br]can be put together to make other shapes. 0:00:21.189,0:00:26.660 You'll be using an algorithm to explain to[br]your partner how to put the puzzle together. 0:00:26.660,0:00:30.710 An algorithm is just a list steps that you[br]can take to complete a task. 0:00:30.710,0:00:34.090 We use them every day with things like shopping[br]lists and recipes. 0:00:34.090,0:00:40.000 If you keep an algorithm simple, there are[br]lots of ways to interpret it and whoever performs 0:00:40.000,0:00:43.570 that algorithm might not get exactly what[br]you wanted. 0:00:43.570,0:00:48.050 If you want to make sure that everyone ends[br]up with the exact same thing, then your algorithm 0:00:48.050,0:00:51.469 will need to be detailed and very specific. 0:00:51.469,0:00:54.899 I'm using an algorithm today to complete a[br]painting. 0:00:54.899,0:01:00.469 I wanted to try doing a painting of some wolves[br]but I'm not the most amazing painter. 0:01:00.469,0:01:04.409 Luckily for people by me, there is paint by[br]numbers. 0:01:04.409,0:01:12.049 There are forty colors and it has little letters[br]and numbers that tell you which color to paint 0:01:12.049,0:01:14.450 each section. 0:01:14.450,0:01:20.049 Paint by numbers tells me exactly what color[br]to use and where. 0:01:20.049,0:01:25.400 It's very specific so I'm able to follow directions[br]and the painting will come out looking awesome. 0:01:25.400,0:01:27.020 It's a great algorithm. 0:01:27.020,0:01:32.640 If the instructions weren't specific enough,[br]my wolves wouldn't look as good. 0:01:32.640,0:01:36.109 When you really want something to turn out[br]exactly the way that you planned it, it's 0:01:36.109,0:01:40.870 best to be extremely precise.
