Y3 How do I program in LOGO?

1. j2launch – 
2. Click on Level 3 
3. Type reset
4. This code draws a single step like the one below:
   • fd 30
   • rt 90
   • fd 30
   • lt 90
5. Press play – you should get this: 
6. Now add this to your code:
   • pu
     setxy -200 50
     pd
7. Challenge 1:  Make this shape by typing more instructions: 
8. Now add this to your code:
   • pu
     setxy 130 100
     pd
9. Challenge 2: Now make a square:  
10. Now add this to your code:
    • pu
      setxy -140 -140
      pd
11. Challenge 3:  
12. Now add this to your code:
    • pu
      setxy 140 – 140
      pd
13. Challenge 4: 

The final picture should look like this:

Is there any way we could make our code simpler?  Some of the algorithms repeat instructions.

Success steps:

• Copy instructions carefully
• Press play to run program
• Make instructions to draw simple shapes including forward, left and right
• Check instructions carefully for mistakes (bugs)

If you have finished, try working through these debugging challenges!

And if you finish that…!  Start a new file and start with this code.

• reset
• setpensize 5

Can you draw a letter?  ~(Diagonal letters will need rt 45 or lt 45)
