1 DESIGN AND TECHNOLOGY GRAPHICAL COMMUNICATION COMPONENT Workbook 2 Name: Year 8: School: Marks allotted: 20

2 Design & Technology Graphical Communication Component CONTENTS Section 1. Isometric drawing Section 2. Orthographic projection Section 3. Electrical circuit diagrams Section 4. Design & Technology project Section 5. Plane and solid geometry Note for the teacher The students' work in each section can be classified as: Very good (4 marks), Good (3 marks), Fair (2 marks), Developing (1 mark). The marks will be awarded for accuracy, neatness, consistency and completion of the exercises. Emphasis is to be made on handling and the maintenance of the pencils and other drawing tools. It is expected that, the skills and knowledge acquired in this workbook, are reflected in the D&T project portfolio and assessed accordingly. Further worksheets (which can be downloaded from the Graphical Communication website can to be attached with this booklet). http//graphicalcommunication.skola.edu.mt

3 A picture is worth a thousand words. This work book is meant to help students communicate their design ideas graphically. Designed by Michael Mallia (Education Officer Graphical Communication) Directorate for Quality and Standards in Education Curriculum Management Department MALTA 2015

21 I can I can draw and colour simple 3D shapes by using the isometric grid lines. I can draw and colour orthographic drawings of basic 3D shapes. I can draw and apply symbols in basic electrical / electronic circuit diagrams. I can prepare the working drawings for my Design and Technology project. I can draw and colour patterns by using basic 2D geometric shapes. I can also recognise 3D geometric solids and some of their nets Maximum mark 20 Very good Good Fair Developing Teacher's signature and remark: Total mark
