Today, you are going to….
- learn about algorithms
- discover how computers follow instructions
1.
Watch video below. It explains what an algorithm is.
BBC Learning What Is An Algorithm. (1:07 minutes long)
2.
Also watch this video to learn more about what algorithms are.

A student will now demonstrate how a computer uses algorithms to perform certain tasks…
(Give a student instructions to make his way from point A to point B, and back to point A again, by giving instructions in the form of an algorithm. E.g.: 2 steps forward, turn L, 5 steps forward, turn R, etc.)
4.
Use the algorithm (in the previous video, at 1:54 minutes)) for making a paper aeroplane!
1) Take an A4 sheet of paper, plus a pen.
2) First write your name all over the paper!
3) Then, follow the steps to fold the aeroplane.
5.
Line up in front of the class and throw your paper planes for fun!
6.
Now you need to follow the algorithm for drawing a computer! Draw while following the instructions in the video below.
(Give each student another peace of A4 paper.)
