Turtle Academy 3

Turtle Academy

Bell Activity

Open Turtle Academy playground.

Using what you've learned last week:

Draw a square with sides of 50 units using repeat

Lift the pen up

Move the turtle forward 50

Put the pen down

Draw a circle with a radius of 150

Key Objectives

All: Understand how to use loops (repeats) to make a shape with any number of sides.

Most: Learn how to nest loops (repeats) inside one another.

Some: Teach the turtle reusable commands to increase your pace further.

What is the command to move forward 50 units?

1. bk 50
2. fd 50
3. rt 50
4. lt 50

What is the command to move backwards 50 units?

1. bk 50
2. rt 50
3. fd 50
4. lt 50

What is the command to turn left 90 degrees?

1. lt 90
2. fd 90
3. lt 45
4. rt 90

What is the command to turn around?

1. rt 180
2. bk 90
3. lt 360
4. fd 180

How do we lift the turtle's pen up?

1. print xcor
2. pd
3. print cor
4. pu

How do we put the turtle's pen down?

1. print xcor
2. pd
3. print cor
4. pu

Lesson activity

Start from lesson 6.

Continue until you finish lesson 9.

When you finish lesson 9, open the turtle's playground and let me know you've finished.

Use the repeat command to draw a square. Each side should be 50 units.

Provide an example of a nested loop (e.g. a repeat in a repeat)

What does this code produce?
repeat 8 [ repeat 5 [setwidth 1 fd 10 setwidth 3 fd 10] lt 45 ]

1. A dashed square
2. A dashed octagon
3. an octagon
4. a circle

If you haven't done lesson 9, skip ahead to it and finish it off.

Teach the turtle to draw a house. Save a picture (win + shift + s) and add it to this question to share.

How do the Turtle Academy lessons prepare us to program in any language?
