Pseudo Codes & Pascal Codes Part 1
Grade 11 ICT Lesson 01 – Sequence and Pseudocode Worksheet
Welcome to Grade 11 ICT Lesson 01, designed for students studying Information and Communication Technology (ICT) in Sri Lanka. This lesson introduces the basic concepts of programming, algorithms, and sequence. Students can use this worksheet to practise writing instructions in the correct order and improve their problem-solving skills.
What Is Sequence in Programming?
Sequence is one of the fundamental concepts in programming. It means executing instructions one after another in a specific order. Each instruction is performed according to the order defined in an algorithm or program.
For example, calculating the total of two numbers involves entering the numbers, adding them together, and displaying the result. These steps must follow the correct sequence to produce the expected output.
Understanding sequence is essential before learning other programming structures, such as selection and repetition.
Pseudocode 10 Questions with Answers
This worksheet provides Pseudocode 10 questions with answers to help Grade 11 students understand basic programming concepts. The exercises focus on writing pseudocode using simple, logical instructions.
Students can practise identifying inputs, performing calculations, processing information, and displaying outputs. These activities help develop logical thinking and prepare learners for more advanced programming lessons.
Try answering all ten questions independently before checking your answers. This approach helps you identify mistakes and understand how pseudocode represents the steps of a solution.
