Pc Logo

PC LOGO Objectives: Students would be able to: 1. Identify angles measurement and direction (left and right). 2. Draw a variety of shapes and lines. Before the activity: I selected a Year 4 student from Sunshine School for this activity. This particular student was not exposed to PC logo software before. I showed him how to type the basic command to run this software for examples; FD 100, RT 90, LT 90, CS and etc. After that, I explained what the basic commands are and what it does in the following table. Basic Commands Command What it does FD 100 Move the turtle forward 100 steps RT 90 Turn the turtle to the right 90 LT 90 Turn the turtle to the left 90 CS Clear the screen and start over HT Hide the turtle ST Show the turtle REPEAT 2 […..] Repeat the commands 2 times I drew two shapes (square and rectangle) so that the student can see that from the basic commands, he can form shapes, lines and etc. it is an advantage for me to choose a Year 4 student because he had learnt different types of angles previously in the Mathematics lesson namely Acute, Right, obtuse and Reflex angles.

During the activity: I allowed the student to play around on his own with the software to get use and to get the idea on what to do for several times. Later, he came up with the shape of a house (5 sided polygons) that he discovered by himself by typing the following basic commands: FD 100 RT 45 FD 100 RT 90 FD 100 RT 45 FD 100 RT 90 FD 145 And this is the shape that is formed: After his discovery, I explain to him the use of REPEAT command so that he will not confuse with the basic commands that I taught earlier on. Instead of typing the long basic commands, he can type: REPEAT 2 [FD 100 RT 45 FD 100 RT 90] FD 145

He also managed to draw another shape that is Diamond by typing the following basic commands: RT FD RT FD RT FD RT FD

45 100 90 100 90 100 90 100

Or RT 45 REPEAT 4 [FD 100 RT 90]

Recommendation: • Besides Mathematics, this activity can be done during creative arts and technology session (Seni kreatif dan teknologi) that is being implemented in SPN 21 (The National Education System for 21st Century) for primary students.
