Some commonly used Pen blocks are described as follows:

                                 block erases everything drawn by the pen.


                               block creates a duplicate of the current Sprite. The image is stamped on the stage.
                     To see the image, click on the Sprite and drag. A duplicate of the Sprite appears behind it.

                                block puts the pen up and stops the Sprite from drawing anything.
                      The Sprite draws a non-stop line wherever it moves using                block.

                       Use                   block to set the colour of the pen to a colour of your choice from the

                     drop-down menu.

                                         block adjusts the pen’s colour,
                     saturation, brightness, and transparency. To modify

                     the pen effects, click on the first text box to choose

                     the effect  you  want  to change.  Then,  click on the
                     second text box to enter  a value that determines
                     how much the effect will be altered.

                                       adjust the pen’s colour, saturation,

                     brightness, and transparency to the specified values.
                     DRAWING A POLYGON


                  Polygons are 2D shapes with three or more straight lines and angles. Examples of polygons are
                  triangle, square, rectangle, quadrilateral, pentagon, octagon, etc.






                      Equilateral Triangle          Square                  Pentagon                  Hexagon
                           (3 sides)                (4 sides)                (5 sides)                (6 sides)








                          Heptagon                  Octagon                  Nonagon                  Decagon
                           (7 sides)                (8 sides)                (9 sides)                (10 sides)

                  To draw polygons in Scratch, follow these basic guidelines:
                       Determine the number of sides: Know how many sides the shape has. This number is
                     used in the Repeat block. For example, use Repeat 3 to draw a triangle and Repeat 4 to

                     draw a square.
                       Draw and turn: Each time you use the Repeat block, the Sprite will draw a line and turn at
                     each corner.
