Wiggles with LYNX
Learn the basics of LYNX:
learn turtle graphics coding
change the code to see what happens
make beautiful patterns
This tutorial is a very brief introduction to the turtle graphics of LYNX Coding.
If you like it, you can learn more LYNX Coding at lynxcoding.club.
With LYNX you can code games, stories with graphics and animations, science simulations, and awesome geometric patterns.
Grade 2 for 'playing with the code'; Grades 4 and up for 'changing the code'
Younger children will have fun making patterns by clicking the buttons. They will be able to change code in the first WIGGLES procedures.
Older children will have to think hard about most of the challenges in this activity.

Getting Started (10 minutes)
Click on this link to open WIGGLES in your browser.
Make some amazing patterns by clicking the buttons!
Let's Change Some Code! (10 minutes)
Click on the EDIT button to open the LYNX Editor.
You will see:
the graphics area on the right
the Procedures Pane on the left
The Wiggle1 button carries out the instructions that are in the Wiggle1 procedure.
Explaining the code!
to WIGGLE1 (tells the turtle you are teaching it a new command (procedure) called WIGGLE1)
pd (tells the turtle to put its pen down so it will draw)
forward 80 (tells the turtle to move forward 80 steps (pixels))
right 60 (tells the turtle to turn right 90 degrees)
back 80 (tells the turtle to move forward 80 steps (pixels))
left 120 (tells the turtle to turn left 120 degrees)
pu (tells the turtle to lift its pen up)
end (tells the turtle you are finished teaching it this procedure)
; click the wiggle1 button 6 times. It makes a star (any line that starts with a semicolon ; is a comment and doesn't run any code. In this case, they are here to give you a challenge!)
; change numbers above to make a smaller star ;-) (Another challenge!)

Challenges!
Try the challenge in WIGGLE1.
See if you can figure out how to make a smaller star. Which number or numbers do you need to change?
