Lessons > Lesson 6 > Delivery

1. Introduction: Troy's Toys example LOGO program.

Pupils should have designed some mazes for homework. They can choose / modify the best ones using simple criteria to aid selection (review, modify and evaluate)

This activity requires pupils to use LOGO to show the path that needs to be cut for the ball bearing to travel around the maze.

Develop this by discussing:

  • Methods of production and terms such as CNC (computer numerical control)

Show the example6a program - Troy's Toys and discuss how this has been written and what it does.

Pupils who have used LOGO before may well see how this program could be improved.

Group activity Show example6a on large screen.
Individual Pupils access this from activity 6/ start.

Show pupils the language6 for this lesson.

2. Writing a LOGO program to follow an example maze.


Using worksheet6a pupils now write a LOGO program using the example given.

There is handout6a about LOGO commands to support this worksheet.

3. Designing and writing their own LOGO program.


Pupils were asked to draw 2 possible designs for their maze. These should now be discussed within the group and final choices made.

Develop this by:

  • Challenging pupils about their choice and discuss simplicity and ease of manufacture.
  • Encourage pupils to opt for the 'easier' option as time may be at a premium.

They should then write their own LOGO program that would cut the path for the ball bearing for the chosen maze. There is a worksheet6b sheet to support this.
4. Plenary: Introduction to procedures.

Activity 7 requires pupils to use procedures, introduce this concept by asking pupils to look for common sets of commands within their own program. These can then be written as procedures and 'called' when required.

Procedures are also called subroutines

Homework:

Give out homework6. This asks pupils to think about automated systems and include some information about them within their final presentation.

You may feel it appropriate to provide the homework sheet in electronic format for those pupils with computer access at home. Consideration should then be given to:

  • How they would return the work and the style - electronic or printed.
  • Virus protection.
  • Authenticity of the work.
