This task requires you to use Scratch. You might have previously downloaded and installed Scratch on your computer, but you no longer need to do that - there is now a web-based version.
web-based Scratch editor
Note that the above page opens in a separate window/tab so that you can keep the task open at the same time.
You do not need to register or log in to use Scratch, but if you do register, then your programs are automatically saved and you can easily share them with other people. In order to submit your task, you will need to go to the File menu at the top of the Scratch editor and download the file to your computer.
If you haven't used Scratch before, then you might want to look at the following links - a page about movement from Subject Pages, and a video introduction to Scratch:
Introduction to Scratch
There is also a video on Scratch and angles to help you with this task: Scratch - Drawing Polygons
You might find the following tiles useful for this project:
tiles for starting your program - e.g. when the flag is clicked - are found in the
tiles for moving and turning are found in the Motion section:
the tiles for repeating things are in the Control section:
the tile for asking a question is in the Sensing section:
(the answer tile contains the response)
the tiles for drawing are in the Pen section:
you can perform calculations using tiles from the Operators
Your first task is to draw a shape. You can use the cat sprite or choose another one, it doesn't matter - just don't get too distracted by what the sprite looks like as it's not an important part of the program!
Try to get your sprite to draw a polygon (a many-sided shape, such as a triangle, square, hexagon, etc.). Below is a list of requirements. Attempt them in order - you can stop after the first one if you are new to Scratch or are finding it hard, or you can add further enhancements to practise your skills and improve your level.
draw a polygon with at least three sides - the sides must join up to leave no gaps
the polygon should be regular - this means that all of the sides must be the same length and all of the angles are the same
ask the user how many sides they would like to have before drawing the polygon
adjust the size of the polygon so that it always fits on the screen, regardless of how many sides there are
create a pattern from the polygons, e.g. a set of similar polygons nested inside each other, or some sort of spiral effect
Remember - you don't need to do all of these things (the last two might be difficult to do together, for example).
