Unplugged Activity | Algorithms

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

and gets across how important it is to be as clear as possible.

This lesson has two parts.

The first uses tangrams,

which are puzzle pieces that look like this.

If you don't have tangrams,

you or your students can cut them out by hand.

Students will have to explain, to a fellow classmate, how to

arrange tangrams in a specific pattern,

but the second student isn't able to see what the original pattern is.

In the second half of the activity,

we ask students to figure out how many

different ways they can fold a piece of paper

to create 16 identical rectangles.

Then, you'll discuss how multiple solutions

can lead to the same end result

and why some solutions are better in certain situations.
