What we will learn today Lesson Objectives: • Define Algorithm , Decomposition and flow charts • Practice all the terms through different activities
Algorithm • is a list of steps you give to computers to solve a problem or get something done
Group Activity Write algorithm for reaching the end part Move Forward (4) Turn Right Move Forward (3) Turn Left Move Forward (2)
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
Decomposition • When you break a problem down into smaller parts to make it easier to tackle / Solve
Making a computer game is quite a complex problem. You could solve this by breaking it down into smaller tasks.
Group Activity Write algorithm for reaching the end part
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.
Group Activity Draw the flow chart for the login process
