This is both a teaching aid and student support document to help students design and build a simple math revision app using the online applab resource: https://code.org/educate/applab The app will ask simple but random addition, subtraction, multiplication and division questions which the user can respond to by typing an answer. The app will check the answer and inform the user if their answer is correct or incorrect. While following this document, students will learn about variables, functions and if / then / else instructions. This document aims to cover the following KS2 UK national curriculum objectives for computing: Design, write and debug programs that accomplish specific goals, including controlling or simulating physical systems. Solve problems by decomposing them into smaller parts. Use sequence, selection. Work with variables and various forms of input and output. Use logical reasoning to explain how some simple algorithms work and to detect and correct errors in algorithms and programs. Be discerning in evaluating digital content.
