===Preparation: recognition of the background colour by the sprite===
'''Time to complete this part: about 25 minutes''' <br/>
We explain that at the beginning we will learn to recognise if the sprite has entered a square of a certain colour, i.e. is it touching a given colour. <br/>
'''Task:''' We ask the students to double click the stage or the stage icon located in the bottom left corner.
We remind them that the appearance of the screen changes, and in the top centre of the screen we can go to the Background tab to change the stage.<br/>
