Within this unit of work, students will learn how to apply the concepts of computational thinking to a range of different problem solving puzzles. The resource is split into four sections; 1. Computational thinking puzzles - a range of different types of puzzles which encourage students to apply the concepts of computational thinking to solve them. Puzzles include mazes, word ladders and even a game of draughts (or checkers)! 2. Logic Gates - students will need to solve the logic gate puzzles to identify if the output is on (1) or off (0) dependent on the gate sequences. This also helps develop Boolean decision making through the use of AND, OR & NOT gates which produce a TRUE (1) or FALSE (0) output. 3. Flowchart puzzles - students need to work out the correct answers to the questions asked dependent on the input information and the flowchart conditions set. Flowcharts include the use of algebra variables which can help support mathematics students. 4. Pseudo code puzzles - students need to read through the pseudo code algorithms and demonstrate their understanding by answering the questions asked. Pseudo code sequences include the use of algebra variables which can help support mathematics students. Each puzzle is given a score. Once complete students check their answers and work out their overall scores and place them in the grid provided. They then compare this with the overall levels to find their overall level: Rookie, Pro or Beast! This can then be used within assessment to see if students are performing at, below or above expected levels. Pack includes a student PowerPoint resource to complete and answers for each puzzle. ***Please Leave a Review!***
