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: 3.Subtract 80 from 100; Add this to 100; Multiply this sum by 50; Divide 120000 by this product 4.Write this as an expression – (120000/(50*(100+(100-80))) 5.Print the result 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 2.Try the circles which different colors. 3.Try the shapes with different size of lines.
Activity #2
Portfolio components	Use the Turtle commands to generate a number of shapes with different colours and shades Students can complete the cards available on http://wiki.sugarlabs.org/go/File:TurtleCard-00a.png http://wiki.sugarlabs.org/go/File:TurtleCard-9.png
