Lesson 3

Bell Activity

Why do we need to use 'loops' in programming?

KO: To demonstrate and use our knowledge of programming to create shapes in Turtle Academy

All
To be-able to use your programming knowledge to create shapes.

Most

To be-able to use your programming knowledge to repeat commands and create shapes.
Some

To be-able to use programming concepts such as loops and repeated commands to create complex shapes and patterns.

Starter

Which one of these lines of code, creates a 'Pentagon'?

1. repeat 5 [fd 100 rt 72]
2. repeat 6 [fd 100 rt 60]
3. repeat 7 [fd 100 rt 52]
4. repeat 8 [fd 100 rt 45]

Can you write the code, which creates a 'Square', using a loop.

The answer is...

repeat 4 [ fd 100 lt 90]

How can we write 'Turtle' to the screen, using a 'label'?

The answer is...

label "turtle

If I wanted to change the 'font size' of the label, I would use...

1. setlabelfont
2. setlabelheight
3. changefontsize
4. changelabelheigjt

Main Activity

We are going to use the turtle academy today, to create a some shapes and patterns...

The person with the shortest line of code that works, WINS!

Who can create the best pattern?

The student who can create the best pattern, wins a golden ticket!

Plenary

How do you change the width of the pen?

1. setwidth
2. changewidth
3. setlength
4. changelength

How do we find out where the turtle is heading to?

1. printheading
2. print heading
3. find heading
4. whereistheturtleheading

What is the correct way to create a 'Septagon'?

1. repeat 7 [fd 100 rt 52]
2. repeat 7 [bk 100 rt 52]
3. repeat 7 [lt 100 rt 52]
4. repeat 7 [rt 100 rt 52]
