#### Mouse Maze - KS3 Algorithm Starter

Mouse Maze is a fun introduction to decomposition, algorithms and iteration (loops). It works well as an extended starter. Print out the simple maze, or distribute the PowerPoint file to students (the mouse icon can be dragged and rotated). They must list the steps required for Mousey to reach the cheese. Decomposition: breaking the problem into smaller steps (i.e. solving the maze) Algorithms: listing the steps to guide Mousey through the maze Iteration: making the algorithm more efficient by repeating parts of it (challenge / extension activity) The download includes: A full set of teacher’s instructions PowerPoint maze for students which can be used electronically or printed out PowerPoint 6 slides showing the task, solution, sections which are repeated, and a more efficient solution. The final slide has definitions of ‘algorithm’ and ‘decomposition’, plus a note to tell students that they have already achieved both during the lesson. Pupils enjoy the activity and it is a great way to introduce the concepts for the first time. I hope you and your pupils enjoy it :)

#### The Imitation Game

A fun lesson revolving around the background of Computers in World War 2. Suitable to use when discussing computing history, ciphers and codes in WW2 and discussing code breaking and decipherment. Students take on the role of 2 Germans who have to encrypt a message and decide an algorithm. Messages are then swapped between groups as allies that attempt to break the cipher. The activity could be made a game by rewarding the most difficult to crack cipher or the team which cracks their cipher quickest. Students will need to know the basics of ciphers such as a Caesar cipher but do not need to know more difficult ciphers. It would also be useful to discuss decipherment methods for example looking for patterns such as “the” “to” or brute forcing the shift. The activity provides a good introduction to cyber security and was successfully used with BSc and MSc students, both enjoyed it however do not let the ciphers get too complex! They can be too difficult to break. Suggested topics after this could be modern cryptography or security principles or computing history such as the Manchester computer.

#### Y7 Computing Algorithms Unit

This is the unit of work I created to introduce my Y7 students to Algorithms, Problem Solving, Pseudocode and Computational Thinking. In the unit, there is the Activity Sheets which introduce: Grid References, Loops, Problem Solving, Trace Tables amongst others. The students trace code as it executes, keeping track of automated buses as they drive. Variables are brought in to track fuel, as well as booleans etc. This unit has been incredibly successful at boosting students understanding of developing and writing algorithms and when we move onto our units in Scratch coding / Python coding, they much better understand the terminiology All in, this can be 'rushed' in 6 lessons, or taking more time to delve into the Computing Acts can take it to 8 and beyond. With new GCSE and IGCSE courses covering some of the material, it is also something that could easily be expanded for students to undertake some of their own investigations into some relevant areas in AI etc.

#### KS2 / KS3 Scratch superunit - introduction and follow-up unit

This bundle contains two units of work for Scratch, including at least 14 lessons in total (some may take longer, depending on programming speed). It can be broken down into two units, or potentially completed in one go. I have completed these with the same students over two years - the introductory unit in Y5 and then the second unit in Y6. However, this could be used with older children with little Scratch experience. The lessons conatined are as follows: Unit 1 Introduction to Scratch - algorithms Joke - sequencing Disco - sequencing / iteration Etch-a-sketch - controlling sprites Maze - Selection / iteration Assessment Unit 2 Flowcharts - algorithms Chatbot - sequencing / selection Scrolling maze - variables Falling fruit - indefinite iteration / variables Breakout - Variables / subroutines Rock, Paper, Scissors - Definite iteration / subroutines Assessment

#### KS2 / KS3 Scratch intermediate unit

This unit is designed to be used after the initial Scratch unit, and contains lessons on flowcharts, sequencing, selection, iteration, variables and subroutines. The games that will be made through this unit include: A chatbot A scrolling maze Falling Fruit game Breakout Rock, paper, scissors Following the flowcharts lesson, the students will complete the other lessons to create the above programs, and then finish with an assessment. The assessment says Y6 at the top as this was the year group I have used it with, but that is because my Y5s completed the introductory unit and so moved onto this in Y6. However, this could be used for KS2 or KS3, depending on programming and Scratch experience.

#### KS2 / KS3 Scratch Assessment

This assessment is similar but more advanced than the introductory Scratch unit assessment in my shop, and includes questions on subroutines and variables as well as algorithms, sequencing, selection and iteration. This is aimed at students who have completed two units of Scratch.
