Computing Important Questions 1 What does decomposition mean? 2 Is it important to be efficient when solving problems? Computer Science – Year 2 – Summer 2 Key Knowledge National Curriculum Objective: • Understand what algorithms are; how they are implemented as programs on digital devices; and that programs execute by following precise and unambiguous instructions. Vocabulary 1 Debug 2 Decomposition 3 Efficient 4 Instructional Language 5 Methodically Computer Science – Sea Drive 3 What is trial and error? 1. 4 Which keys on the keyboard would you use to go right, left up and down? 2. 5 Can you make something happen following instructions? – 3. Identifying correct programs: This activity introduces algorithms as a set of instructions and shows how algorithms are used by a computer to create a program to carry out a specific task. Executing programs: Pupils need to read a program and identify the corresponding instruction to successfully navigate the ship to the treasure. Extending identifying correct programs: In this activity, pupils need to select which is the correct algorithm to lead the ship to the treasure. 6 7 8 9 Find and remove errors. Break a problem into parts. To achieve a goal using the quickest route. Left, right, forward etc. Reads instructions carefully following them in an orderly manner. Simulating Creating a program to make something happen e. g. fly a plane. Terminology Language linked to a specific subject e. g. computing. Trial and To accomplish a task by Error trying different methods until you find a solution. Unambiguou Instructions that are clear s Instructions and easy to follow. Expected Prior Learning • • Beginning to understand the term ‘algorithm’ and ‘degree’. With support can describe and write a simple algorithm for a specific task.
