ONLINE LOGO

Instructions

This is a simplified version of the programming language Logo. Use it to draw shapes by moving the turtle (arrow) around the screen using the following commands:

fd (Forward)

Example: fd 10 will move the turtle forward ten steps.

bk (Backward)

Example: bk 5 will move the turtle backwards five steps.

rt (Right turn)

Example: rt 90 will turn the turtle 90o to the right.

lt (Left turn)

Example: lt 45 will turn the turtle 45o to the left.

ct (Center turtle)

cs (Clear screen)

pu (Pen up)

The turtle can move without drawing a line.

pd (Pen down)

repeat

Example:
repeat 4[fd 10 rt 90]
will draw a square.

pc (Pen colour)

Example: pc 2
0 = black, 1 = blue, 2 = red etc

Logo PatternLogo is a simple programming language devised by Seymour Papert for educational purposes. Students can control the movement of a 'turtle' which draws lines on the screen. Students learn about lengths and angles while creating diagrams and patterns. The learning takes place as students experiment, get feedback and revise their actions in a non-judgmental environment. Students develop a much better understanding of angles being an amount of turning than they do from more traditional, static exercises.

Logo is a wonderful application to use when learning about the properties of shapes and angles. Using the repeat command to draw a triangle usually results in a significant and poignant learning moment as students grasp the difference between the internal and external angles.

You can find in the left panel above instructions and a series of challenges for the student who has not used Logo before. Click the blue buttons to move through the challenges. Students can use the snipping tool to capture pictures of their work which they can paste into their notes.

Please send Transum pictures of anything magnificent you produce with this application or tell us about your blog if you have one.

Yuri.T,

A great way to create shapes and many other amazing images. I particularly liked the spectacular fireworks... tres bien and fantastique!

Hannah, West Yorkshire, England Aged 11

I used this for my ICT homework and I was glad you didnt have to download anything as I've used LOADS of memory on my computer. This was really useful but maybe you could put some hints in, because challenge ten was really difficult for someone my age.

Kieron, North Tyneside

Repeat 250[fd 20 rt 89] to make a circle.

Jack Mac, Taupo, NZ

If you type in:
repeat 360 [fd 1 rt 1] it makes an arc.

Jack Mac, Taupo, NZ

Guide to colours:
PC 0 Black
PC 1 Blue
PC 2 Red
PC 3 Green
PC 4 Yellow
PC 5 Purple
If you mix red and plue it makes purple automatically.
I assume if you mix yellow and blue it might make green but I haven't tried yet.

Jack Mac, Taupo, NZ

Repeat 250[pc 1 fd 20 rt 89 pc 2 fd 20 rt 89] makes a vortex with a mixture of hues including purple.

Andrew Butler, Island Pacific Academy

Also, try do repeat 1000 [pc 4 fd 5 rt 35 pc 2 fd 5 rt 35] to make the Fire Circle.

Andrew Butler, Island Pacific Academy

I really love this website especially the colors in it. But, I'm stuck on challenge number 10. I can make the stems and the little triangle on the bottom, but I cant make the flowers. But the really cool thing is that if you start out with the normal color (which is gray) and do "repeat 50 [fd 5 bk 5] it makes it darker.

Lori, Lori

rt 90 pc 3 repeat 500 [fd 5 rt 89] makes a green circle.

Aaron, Island Pacific Acadamy

It is cool making flowers but how do you make one.

Andrew, Island Pacific Academy

Can someone tell me how to make the flowers, I'm finding it so hard.

Ryan,

Hi there can you please help me to create those flowers on challenge 10 anyone?

MG, MG

Great to be able to use Logo online without needing to install anything.
Should the "turtle" move with the drawn line?

[Transum: Sorry MG. The problem was caused by an incomplete software upgrade. Thanks so much for letting us know. The problem has now been corrected.]

That is how you do 1 flower for challenge 10, a bundle of flowers, configure it all you want, give it colour, add the bundle rotation, or show off to your friends.

Ree, Europe

How would you draw an 'N'.

Lara, England

I really loved this. I use the computer a lot and I also use this website a lot so for me all of the challenges were easy and also I like experimenting the different things I can make.

00,

Do repeat 100[fd 20 rt 89] = cool circle.

Omar Hadeed, Kuwait

We started learning how to use Logo back in grade 8. I remember my first command, we started dividing 360/3 = 120. And so, I used repetitive capability to make fun shapes like this one:
"repeat 120 [fd 5 bk 5 rt 3]"
Try for yourself. This tool is a powerful designing operator, I would waste hours of my day punching commands that return fabulous sketches !!

Gary, England

I used to be able to create procedures and they were stored on this great, really useful website. However, they've disappeared and I can't create any more. Is there a problem?

[Transum: Sorry Gary, procedures aren't available. Logo is on the plan to be updated later this year.]

So, back in that time the best I made was a circle that erases himself after drawing, then advance and then draw and erase again, so it was an animation, a circle that pass from side to side of the screen, that was the max my computer can handle, in this web I could make the base, but I cant find the way to erase before drawing... still here is not needed becayou dont see the drawing in real time, you only see the last result so I emulated the program whithout erasing, here is it, hope you like it and maybe add the animation erasing a circle after finishit and before to move to the nexty one, only if your system can draw it in real time :
pu rt 270 fd 28 rt 90 pd pc 14 repeat 50fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 pu rt 90 fd 1 rt 270 pd fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18 fd 1 rt 18.
