Demonstrate the possibilities of movement using the Turtle
Visualize space, co-ordinates and shapes through movement and vice versa
Familiarization with the move/ draw/ colour functionalities of Turtle Art
Familiarization of ways of defining parameters - movement, co-ordinates and colour
Hands-on Activity
Activity #1 (Part A)
Making the Turtle move without a trace
Instruct the turtle to move by repeating a set of instructions
Determine/ identify the shape the turtle will trace; pay attention to the orientation of the turtle
View this with the co-ordinates and without the co-ordinates
Count the number of times instructions are repeated
What is the relation, if any, between the number of times the instruction is repeated and the shape traced by the turtle
Color the palette

Hands-on Activity
Activity #1 (Part B)
Making the Turtle move with a trace
Change the pen parameters - colour and thickness
Instruct the turtle to move by repeating a set of instructions
Determine/ identify the shape the turtle will trace; pay attention to the orientation of the turtle. Is this the same/ different as what you expected when you did not trace? If there is a difference, what is different and why?
Describe the turtle's movement (in words)
View this with the co-ordinates and without the co-ordinates
Count the number of times instructions are repeated
What is the relation, if any, between the number of times the instruction is repeated and the shape traced by the turtle. Show this using "Run" and "Step" options to understand the movement
Colour the palette with the given values.
And execute the code in the the following three sequences and find out why the output is different
Screenshots for the above activity
Questions and Assignments
See the picture here. What should the command have been for this? How many times were the instructions repeated?
Use the Turtle move commands to generate a shape
For a given shape, write the Turtle commands
Week 2
Week 2
Make the Turtle Move with different inputs and to display outputs
Objectives
Familiarization of ways of defining parameters - movement, co-ordinates and colour
Visualize space, co-ordinates and shapes through movement and vice versa
Deconstruct the logic in a sequence of instructions
Hands-on Activity
Activity #1 (Part A)
Make the turtle move to a given co-ordinate position; turtle can be moved by specifying the end position also
Demonstrate movements of the turtle using the angle block
What does the radius mean? What does the angle instruct the turtle?
To draw a circle, what would you instruct the turtle?
See the picture here. What should have been the commands? (Hint : it involves co-ordinates and angles)

Hands-on Activity
Activity #1 (Part B)
The Turtle can also display outputs using the Print block from the extra options palette.
The Turtle can be used to label a figure, using the Show block to be found on main palette.
The Turtle block to be found on extra options palette allows you to change the colour of the Turtle
Here is a piece of programming to show how to print and how to change the colour of the Turtle and label a text.

Guess why the text “Square” appears 4 times. What can you do to avoid it?
