Managing slides ( 1 / 5 )

1. Managing slides (1/5) • When you create a multi-slide presentation in Scratch you need • to select a good background picture • to create buttons to be pressed to step to the next slide • to plan the content elements inside slides

2. Managing slides (2/5) • Inform the slide-reader by a message appearing over a part of the screen • Use 'say' function with a message embedded in an 'if' statement • Condition of 'if' is 'touching mouse-pointer'

3. Managing slides (3/5) • Define events and event-handlers • E.g. when Sprite6 is clicked it sends event 'B2' • E.g. when 'B1' event is received by a sprite it can process a special command

4. Managing slides (4/5) • Use 'show' and 'hide' functions to visualize new arrange of contents for the next slide • e.g. the figure bellow shows that the associated sprite will hide or show depending different events ['B1', 'B2']

5. Managing slides (5/5) • Narrate your slides with your own voice • e.g. use 'play sound ...' function then use 'Sound Recorder' window
