Activities |
|
Outcomes |
|
Children: |
- Use the procedures from the last task to write a new procedure called 'hum'. Use the square (Pooh) and the triangle (Tigger) and penup and pendown to draw a simple house. You will need to rotate the turtle by 60 degrees before 'putting' the roof on. Show the children that every time you type 'hum', the house appears. Divide the children into pairs and ask them to write their own version of 'hum', maybe changing the size of the square and the triangle. When they have done this ask them to use 'hum' to create a number of houses and ask them to print their results.
|
|
- learn how to combine procedures to form a new procedure
|
|
Points to note |
Children will need to be able to edit their procedures when they make mistakes. Children who find the work difficult may be given a copy of the 'hum' to work from. Children who find this easy could be asked to create 'hums' for different sized houses.
