|Week 4
|Arithmetic manipulation using Turtle Art.
|-
|Objectives
|
#Demonstrate the use of arithmetic operations and display results
#Understand the logic of nesting operations
#Combining input parameters, action sequences and evaluating conditions to make Turtle move
|-
|Steps
|
1.Introduce the numbers palette
2.How to print results from simple arithmetic operations:<br>
3.Subtract 80 from 100; Add this to 100; Multiply this sum by 50; Divide 120000 by this product <br>
4.Write this as an expression – (120000/(50*(100+(100-80)))<br>
5.Print the result<br>

6.Print random numbers using the random number function
|-
|Steps
|
#Combining values
#Conditional commands combined with arithmetic operations to create a shape
#See file called “Conditional Operations” for code.
|-
|Hands-on activity
|Activity #1
1.Draw a series of equal radius circles with increasing X,Y coordinates<br>
2.Try the circles which different colors.<br>
3.Try the shapes with different size of lines.<br>
