  1. Design and Technology Academic Year 2017/2018 Grade 7 First Semester

  2. What we will learn today Lesson Objectives: • Define Algorithm , Decomposition and flow charts • Practice all the terms through different activities

  3. Algorithm

  4. Algorithm • is a list of steps you give to computers to solve a problem or get something done

  5. Algorithm for making a cup of coffee: Discuss

  6. Algorithm for making a cup of coffee: Discuss

  7. Book Activity

  8. Group Activity Write algorithm for reaching the end part Move Forward (4) Turn Right Move Forward (3) Turn Left Move Forward (2)

  9. Draw a smiling face in triangle of the top side of the page Game / Book Activity Write your best friend name in the triangle of the right –hand side of the page

  10. Decomposition • When you break a problem down into smaller parts to make it easier to tackle / Solve

  11. Making a computer game is quite a complex problem. You could solve this by breaking it down into smaller tasks.

  12. Group Activity Write algorithm for reaching the end part

  13. Flow charts • A flowchart is a diagram that represents a set of instructions. Flowcharts normally use standard symbols to represent the different types of instructions. These symbols are used to construct the flowchart and show the step-by-step solution to the problem.

  14. Flow chart

  15. Group Activity Draw the flow chart for the login process

  16. Group Activity Write algorithm and draw a flow chart for brushing your teeth

  17. Algorithm for brushing teen Put toothpaste on toothbrush Brush teeth If your tooth clean Return tooth brush Else brush teeth again
