Use this post if you haven’t managed to create your own shape.

1. Open this j2code file – it is a shape ready in the top left corner.
2. Save it
3. To get a row of shapes, put in the bold instructions like this:
   • reset
   • setpensize 4
   • repeat 5
   • [
   • my shape instructions
   • ]
4. To turn the corner: add a rt 90 on the next line after the ]
5. To make a square of shapes:
   • We want to repeat the row of shapes and turn, 4 times
   • repeat 4
   • [
   • code for row and turn
   • ]
6.  Change the repeat in the row code so that it takes up the whole square.
7. Can you make an inner square?
   1. Copy and paste your code (apart from the reset, setpensize) so you have two copies
   2. Change the second setxy  numbers to -190 190
   3. Change the repeat of the second row so it fits inside the outer square.
8. What about a third inner square?!

• Go to j2launch – j2code – LOGO
• Start your program with:
  1. reset
  2. setpensize 5
• CHALLENGE:  Write instructions in LOGO to make this picture.
• 
• Use as many of these commands as possible:
  1. Movement:   fd bk rt lt (with a space then a number)
  2. circle (with a space and a number)
  3. repeat 4 [  …   ]
  4. arc 90 30   – can you work out how this works?  (One number is the size, the other is the angle)
• Use the code below to move around the page without drawing:
  1. pu setxy 100 100 pd   (The numbers are x y coordinates and the screen goes from -250 to 250)
• If you have finished the picture, can you add an eyebrow?
• 

Success steps

• Use known commands
• Use left-hand side panel to copy correct commands (syntax)
• Create a page with several elements
• Move around the screen using pu setxy …. pd
• **Learn new commands. eg arc, spiral code
• Check code and debug

Further challenges…

1. 
2. Different shape for the eye (still using repeat)
3. Add hair by using repeat and doing a zig-zag
   1. Can you make the hair curve?
4. Make ears using a spiral – open this file, read it carefully and experiment with the code, before copying into your project.

And if you’ve finished that, have a go at these Debugging Challenges and save them in your files.  DO NOT GET/GIVE ANY HELP.

Computing colours:  LOGO

• Red – copy example code; explore and experiment
• Orange – test and debug own code
• Yellow – use repeat
• Green – use procedures; nested repeats
• Blue – use variables
• Purple – create own LOGO project with variable and procedures

1. Typing,com – 5 minutes
2. Go to j2launch – j2code – LOGO
3. Start your program with:
   1. reset
   2. setpensize 5
4. Use as many of these commands as possible:
   1. Movement:   fd bk rt lt (with a space then a number)
   2. circle (with a space and a number)
   3. colour “yellow
   4. fill
   5. repeat 4 [  …   ]
   6. arc 90 30   – can you work out how this works?  (One number is the size, the other is the angle)
5. Use the code below to move around the page without drawing:
   1. pu setxy 100 100 pd   (The numbers are x y coordinates and the screen goes from -250 to 250)
6. Are there any other commands you can show that you can use?

Success steps

• Use known commands
• Use left-hand side panel to copy correct commands (syntax)
• Create a page with several elements
• Move around the screen using pu setxy …. pd
• **Learn new commands
• Check code and debug

Success steps

• First we will play some keyboard games…
  • Know the home keys
  • Find them (with your eyes shut!)
• Log into j2e
• LIME, MAPLE – complete Computing at Home survey
• Log into typing.com with your Google account
  • In Account at the bottom, join a class – trype in “mrwtypingclass” and select your class
  • Start from lesson 1
    • Start at the home keys
    • Use correct fingers for typing

Question – How could we link j2review to your progress in typing?  (It needs a file in “my files” to be able to grade).

• j2launch – Find the typing folder then Typing speed test
• When you have finished the test,
  • Printscreen (Look for PrtScr on you keyboards)
    • Ctrl-silver blob (F10#) on the PC keyboards
    • Fn-PrntScrn on some laptops
    • Just press PrntScr on most laptops
  • Paste (Ctrl-V)  this into a new j2e5 page called Typing
  • If you can’t Printscreen, type your speed into a j2e page called Typing – put today’s date next to it.

• Please finish Fetch and Doggy data searching activities
  • SC
    • copy and paste webpage link
    • use 3 or 4 keywords to search
    • find and write the answers to the questions
• You then have a choice of:
  • Budd:e + make a page of ideas in j2e
  • Digital Compass + ideas page in j2e
  • Information treasure hunt on Google Classroom
