Get+the+Picture+-+Extension

Create your own ** When I receive ** scripts to draw each of the shapes you have already created (square, triangle, pentagon, etc.). Remember to use ** broadcast and wait ** to trigger the ** When I receive ** blocks. Once you have done this, adapt your program for: to use a ** broadcast and wait ** block for the repeating shape.
 * Extension 1: The main event**

**Extension 2: Our house**

Draw a house like the one shown opposite.


 * Write an algorithm – that is, plan the steps out on paper –**** before you try to code this! **

You will need to use ** penup ** and ** pendown ** blocks.


 * Hint**: Think about how you could use the **broadcast and wait** command to reduce the amount of code you create.

**Extension 3: Mmm… doughnuts** Adapt the pattern above to create a multi-coloured doughnut shape.


 * Write an algorithm before you try to code this!**
 * Hint**: There are 36 circles, but the pen moves slightly – with the

pen up – before putting the pen down and drawing the next one.

The program also uses the change pen color by block to make it colourful.

**Extension 4: The Olympic Rings [1]**

This is hard! Try to write a program to draw the five Olympic rings. **Write an algorithm before you try to code this!**


 * Hint**: make each circle using a ** broadcast and wait ** command and think about the spacing between the centre points.

The five rings represent the five continents of America, Africa, Asia, Australasia, Europe. The colours – blue, yellow, black, green and red on a white background – were chosen because every nation had at least one of them on its national flag.
 * Did you know…?** The Olympic flag was flown for the first time at the 1920 Summer Olympics in Antwerp, Belgium and has been flown at every Olympic Games ever since.
