(Amy Hirotaka - Code.org)[br]Lesson six teaches algorithms

0:00:08.700,0:00:12.000
and gets across how important it is to be as clear as possible.

0:00:12.000,0:00:13.500
This lesson has two parts.

0:00:13.500,0:00:15.570
The first uses tangrams,

0:00:15.570,0:00:18.680
which are puzzle pieces that look like this.

0:00:18.680,0:00:20.100
If you don't have tangrams,

0:00:20.100,0:00:22.330
you or your students can cut them out by hand.

0:00:22.330,0:00:25.600
Students will have to explain, to a fellow classmate, how to

0:00:25.600,0:00:28.000
arrange tangrams in a specific pattern,

0:00:28.000,0:00:31.900
but the second student isn't able to see what the original pattern is.

0:00:31.900,0:00:34.200
In the second half of the activity,

0:00:34.200,0:00:36.200
we ask students to figure out how many

0:00:36.300,0:00:38.500
different ways they can fold a piece of paper

0:00:38.500,0:00:41.100
to create 16 identical rectangles.

0:00:41.100,0:00:43.600
Then, you'll discuss how multiple solutions

0:00:43.600,0:00:45.200
can lead to the same end result

0:00:45.200,0:00:48.140
and why some solutions are better in certain situations.
