The lesson on computational thinking

3
00:00:10,100 --> 00:00:13,769
is intended to teach you how to take a big, difficult problem,

4
00:00:13,769 --> 00:00:17,420
and break it down into several simpler problems.

5
00:00:17,420 --> 00:00:20,650
The goal in this lesson is to write a set of instructions

6
00:00:20,650 --> 00:00:23,100
that someone can follow to draw one of the monsters

7
00:00:23,100 --> 00:00:24,700
included in this lesson plan.

8
00:00:24,700 --> 00:00:28,509
Students will break into groups to write instructions

9
00:00:28,509 --> 00:00:30,500
and then will switch them with another group

10
00:00:30,500 --> 00:00:32,000
that will have to draw the monster.

11
00:00:32,500 --> 00:00:34,400
Groups will write instructions

12
00:00:34,400 --> 00:00:37,000
using the four steps of computational thinking:

13
00:00:37,000 --> 00:00:38,300
decomposition

14
00:00:38,300 --> 00:00:40,000
pattern location

15
00:00:40,100 --> 00:00:41,900
abstraction

16
00:00:41,900 --> 00:00:43,200
algorithms

17
00:00:43,200 --> 00:00:46,000
First, groups will decompose the task,

18
00:00:46,000 --> 00:00:48,000
which means make a game plan.

19
00:00:48,000 --> 00:00:52,719
Then they'll look for patterns between all the monsters in the catalog.

20
00:00:52,719 --> 00:00:56,370
When they come across differences between the monsters

21
00:00:56,370 --> 00:00:59,870
they'll abstract out, or remove, those details.

22
00:00:59,870 --> 00:01:04,430
For instance, one monster in the catalog has vegitas eyes

23
00:01:04,430 --> 00:01:06,800
and another has spritem eyes,

24
00:01:06,800 --> 00:01:08,270
but they both have eyes.

25
00:01:08,270 --> 00:01:12,800
So we can write a line that says, "This monster has _blank_ eyes."

26
00:01:13,000 --> 00:01:16,300
So students will be able to write a set of instructions,

27
00:01:16,300 --> 00:01:19,729
called an algorithm, that lists the monster's parts

28
00:01:19,729 --> 00:01:22,000
with blanks for what the style should be.

29
00:01:22,000 --> 00:01:24,900
This is the set of instructions they'll pass to

30
00:01:24,900 --> 00:01:28,000
other students to recreate their very own monster.
