#### Cluedo murder mystery riddle - adaptation from Einstein's '5 houses' logic puzzle

**Mr Black has been found dead at Tudor Manor. ** You are the lead investigating detective. You have all six suspects brought to the main hall of the mansion, seated next to each other around a circular table. Every one of them has a motive to murder Mr Black, but only one committed the crime. Can you solve the case and bring the killer to justice? Who killed Mr Black? What weapon was used? Where was the weapon hidden? This activity is an adaptation of mine based off Einstein’s ‘five houses’ logic problem Students extract relevant information from text; create an appropriate data structure to record these facts; and use a process of elimination to solve the problem I have been using it with KS4/5 Computer Science classes to demonstrate computational thinking (abstraction and decomposition)

#### [GCSE + IGCSE] Computer Science Trace Tables, Algorithms and Efficiency

This is an excellent resource that I have created and used with my Y10 and Y11 GCSE class (Y10 are IGCSE, and is relevant to both courses) I use this as a collaborative carousel activity where students in pairs (or however you want to work it) look at two algorithms at a time, tracing the values of the variables. This is a problem solving activity that should hopefully challenge students Computational Thinking, as well as revising their skills with Trace Tables and predicting output of code, as well as spotting Logical errors. I have also used it to introduce the idea of preprocessing. This series of activities leads nicely into more challenging activities, such as sorting of data. When I teach this lesson, I use some theory resources and plenary activities, as well as some on-line quizzes over 3 lessons. Had a looking for learning observation whilst using these activities and feedback from observation was excellent. Having reviewed it with students, their feedback was (a long with the Data Structures activities uploaded and used prior to these activities) is that it really helped them to visualise how data is stored and manipulated in arrays, as well as introducing preprocessing (which appeared in this year exam) as well as revising trace tables. Allowing the students to work in collaboration, discussing with one another and doing some peer review tied in neatly with some of the observational areas which we are looking at with ATL and Life After Levels. I was also toying with doing this as a group presentation activity, where the students can ‘lead’ this activity and ‘Be the Teacher’ explaining the inefficiency of their algorithm and how the data can be as issue also. This was also a perfect opportunity to revise why we use arrays in the first place - as I got students to re-write the code without arrays and it was a crazy series of IF statements, so plenty of scope to draw in other areas of the course.

#### OCR J276 Computer Science Paper 2 Revision - Knowledge Organisers

The new OCR Computer Science 9-1 GCSE specification (J276) has a lot of new knowledge for the students to learn. I have created these knowledge organisers for my Year 11 Computer Science students. I have tried to make them as compact as possible - trying to fit the entire topic onto one side of A4 (two at most). The students used them for their Paper 2 mock exam in December. The feedback was really positive - they found them really helpful to recap the topic and have now also seen how they can be used to help answer the exam questions. As you can probably guess they have taken me many hours to put together and I have been improving them, and correcting them as I have been using them and working with the practice questions to make them as useful as possible. This is the first time I have sold anything on TES, I have found the new spec pretty daunting - so I do hope these can help a few people. Please do give me any feedback if you think there is anything missing and I will make any necessary changes. Thanks Rachel
