1 1 repeat 6 forward Getting Started Getting Started Getting Started Getting Started repeat 6 forward 100 forward 100 number of sides draw a line 1 60 turn 60 BIGGER OR SMALLER repeat 6 forward 38 change this number 60 SQUARE TRIANGLE repeat 4 forward these numbers have changed repeat 3 forward these numbers have changed GETTING STARTED repeat 4 forward x 4 = is all the way around

2 2 set color 7 repeat 360 forward 1 1 Drawing Circles Circles Drawing Drawing Circles Circles It takes a lot of little steps 2 set color 7 choose a color BIGGER repeat 360 forward change this number 2 1 step turn But it still turns 360 repeat 360 SMALLER forward repeat 180 forward x 1 = 360 change these numbers DRAWING CIRCLES repeat 180 forward x 2 = is all the way around

3 3 Spinning Circle repeat 360 forward back Spinning Circle Spinning Circle Spinning Circle REPEAT IT 45 TIMES repeat 45 3 forward back forward back the heading changes SPINNING CIRCLES CHANGE COLORS set color 80 CHANGE PEN SIZE set pensize 45 o If you repeat it 360, the turtle does a full circle 1 set pensize 10

4 set pensize repeat set color heading forward 290 back 290 ribackght 1 Rainbow Rainbow Rainbow Rainbow Change the pen size 4 set pensize repeat heading = 0 heading = 20 set color heading forward 290 back 290 ribackght 1 the next time through the heading will be 1, then 2, 3, 4... until 359 If you repeat 360 times, the turtle does a full circle RAINBOW the first 20 repeats 1 makes the heading change by one each time

5 5 Rainbow Math Rainbow Math Math 5Rainbow COLORS colors will range from 0 to 100 heading range from 0 to 100 heading/360 x 100 goes from 0 to 100 } the turtle goes off the screen and back to the center number of degrees in a circle number or colors available RAINBOW MATH TRY THIS Change this number and see what happens

6 6 Turtle Shades Turtle Shades Turtle Shades Turtle Shades SHADES shades range from 0 to 200 heading range from 0 to 100 the turtle goes off the screen and back to the center number of degrees in a circle number of shades available SPINNING SHADES TRY TO CREATE THIS IMAGE

7 7 Arc Arc Arc 2 7 arc angle = the turtle ends pointing up as it started forward radius = 100 forward ARC CAN YOU MAKE...

8 8 Arcs in a Circle Arcs in a Circle Arcs in a circle Arcs in a Circle do it once turn 10 o do it again and turn 8 choose a color choose a shade and fill the screen do it 10 times If you repeat it 36 times, the turtle does a full circle 10 x 36 = 360 ARCS IN A CIRCLE = 100

9 9 Rays left 4 9Rays Rays it is a circle inside the turtle goes forward but it doesn t come back all the way forward back think about forward 4 left 4 left 4 RAYS CHANGE SOME NUMBERS AND SEE WHAT HAPPENS

10 10 Candy Vortex Candy Vortex Candy Vortex Candy Vortex pensize gets smaller as the turtle turns (359, 358, 357..) 10 the color and shade are set by the turtle s X and Y position CANDY VORTEX EXPERIMENT! SWITCH AROUND THESE BLOCKS:

11 11 Smooth Candy Candy Smooth Candy Smooth Candy sets a slightly bigger pen size 11 changes the colors more slowly changes the shades more slowly, favouring lighter shades SMOOTH CANDY USE THESE BLOCKS TO CHANGE THIS STACK:

12 12 Spiral Spiral Spiral this is like doing forward forward forward forward box1 starts at 0 adds 10 each time SPIRAL change this number and this one too

13 13 Bent Spiral Spiral Bent Spiral Bent Spiral make a square spiral 91 makes a bent square spiral BENT SPIRAL Try making a bent triangle spiral

14 14 Spin Spin Rainbow Rainbow Spin Rainbow Spin Rainbow Click and type to change its name the blocks automatically change names 14 each segment is slightly different color SPIN RAINBOW It is good to use a name that indicates what is stored in the box

15 15 Color Squiral Color Squiral Color Squiral Color Squiral The color and shade of the pen change The color depends on the X coordinate The shade depends on the heading 15 COLOR SQUIRAL try changing this number try adding arithmetic here

16 16 Flag Flag Flag 3 forward the turtle ended where it started } forward forward back } forward FLAG Try other things where the turtle ends where it starts

17 17 Flags Flags Flags create a block 2. Click and type a name Place this block on top 3. A new block with that name appears 4. Use it in other stacks makes 9 flags FLAGS Create our own blocks and use them in different stacks

18 18 Windmill Windmill Windmill 18 a box inside a box inside a box... WINDMILL Change the windmill or create something new

19 19 Spin Square Square Spin Square make a square turn 36 o 19 and another... and another... If you repeat it 10 times, the turtle does a full circle 10 x 36 = 360 and another... SPIN SQUARE once you name a stack, a block appears here

20 20 Flower Flower draw a square of any size length of a side start at 0 20 square 90 square 60 square 30 make size bigger FLOWER make some changes and see what happens

21 21 Hexrainbow Hexrainbow Hexrainbow Hexrainbow color will range from 0 to 86 start at 0 draw 6 hexagons of any size changes its value adding 2 each time size = = 2 size = = 4 size = = 6... size = = HEXRAINBOW size determines how big it is

22 22 Random Stars Stars Random Stars Random Stars pick a random color from 0 to try this several times what values did you get? draw a star of a random color at a random place pick a random X position, from -300 to 300, and a random Y position, from -200 to 200 RANDOM STARS try using random with pen sizes and shades...

23 23 Not That Random Not That Random Not That Random Not That Random pick a random color from 0 to draw a star of a random color at a not that random place possible X values: possible Y values: NOT THAT RANDOM pick a dark shade pick a thick pensize pick a lighter shade pick a thinner pensize

24 24 Bubbles Bubbles Bubbles 24 pick a random positon on the screen store in box1 a value between 200 and 800 set the pensize and shade so the bubbles get smaller and darker towards the bottom of the screen BUBBLES try making the bubbles lighter and bigger towards the bottom

25 25 Glow Glow Glow Glow 25 place the turtle at the bottom left corner (off the screen) pick a color in a small range draw a curved line, then retrace it

26 26 Garden Garden Garden pick a color, a shade and draw a star 26 draw tulips at the corners of this pattern

27 27 Not Quite Plaid Not Quite Plaid Not Quite Plaid Not Quite Plaid 27 pick a color, a shade and a pen size stores 0 or 1 in box1 if box1 = 0 --> draw a vertical line if box1 = 1 --> draw an horizontal line

28 28 Swirl Swirl Swirl 28 draw a squiggle map 0 to 360 range to 0 to 600 range then retrace it 360 x 1 = 360 If you repeat it 360 times, the turtle does a full circle
