This FREE simple Christmas activity teaches pupils about how bitmap images are constructed. They need to convert the binary numbers into denary and then use them to create various images. They are shown the final image as well as the binary numbers used to create the bitmap image. Suitable for Year 7 or 8 as a fun Christmas lesson. Please note: the Excel spreadsheet is protected and only some cells are open for the pupils to type into.

This digital activity is entirely self-marking and helps re-enforce converting from binary to denary and denary to binary. It consists of 4 challenges each with progressively harder challenges where students complete against each other to see who can complete the challenges in a given amount of time. Ready to use with absolutely no preparation and this is a must have activity for the busy computer science teacher. The next question will only appear once the previous one has been completed correctly and students are given a clear “Correct” or “Try Again” message to tell them if they have the answer correct. WHO IS IT FOR? This activity if suitable for any students who has learnt how to convert from binary to denary and denary to binary and wants to practice those skills. It starts of with converting 5-bit numbers but progresses to 8-bit numbers and the challenges progress. Ideal for a “Teaching to the top” teaching methodology. WHAT IS INCLUDED? This resource includes an Excel spreadsheet that the students access which contains an instruction page and the 4 challenges. It also includes a second Excel spreadsheet which contains the answers for the teacher’s reference if needed. The competitive element where students are completing against their classmates means this is a fun and challenging activity that your students are sure to enjoy. Grab it now and add it to your teacher’s toolkit.

This free activity provides a hands-on, practical activity to help your pupils learn about binary to hexadecimal conversion and binary, denary, hex conversions. 2 different puzzles are provided in this resource which are simple to prepare and easy to include in your lessons. SIMPLE HEX PUZZLE In this puzzle pupils need to fit the triangles together so the matching edges are of equal value. One edge will contain a binary number and the other edge will have the corresponding hexadecimal value. Works well as an individual or paired activity. Includes the values from 1 to 15 (1 – F). NUMBER BASES PUZZLE In this puzzle pupils need to fit together squares so the edges match in value. Some are binary values, some are hexadecimal values and some are denary values. This is much harder than the simple hex puzzle and works well as a paired or group activity. Includes the values 0 to 255 (in denary). HOW TO PREPARE THE PUZZLES These are very easy to prepare and can be re-used with multiple classes. You need one printed page for each puzzle you want to use, for instance if you have 30 pupils and want them to work in pairs you will need 15 copies of the puzzle. Print on card or print on paper and laminate for longer durability. Cut into separate shapes along the straight edges and put each set in a separate envelope. Give one envelope to each pair of students and ask them to solve the puzzle. You may want to provide some scrap paper for your students to use to work out the answers, especially for the number bases puzzle. Please note this is a PDF file which cannot be edited. Download this FREE hexadecimal puzzle set today and add it to your teacher toolkit. You’ll be amazed at how effective this activity is at helping your pupils become more confident with converting between different number bases. You may also be interested in these wonderful hexadecimal lessons which include an editable copy of these same puzzles.

A great introduction to understanding sorting and searching algorithms including bubble sort, insertion sort, merge sort, linear search and binary search. These ready to use sorting and searching algorithms lessons will save you hours of preparation and can easily be adapted to meet your own requirements. WHAT IS INCLUDED? In this unit you have 3 ready-to-use lessons: Bubble sort Insertion and merge sort Linear and binary search . These lessons include everything you need such as: a very high-quality accessible PowerPoint presentation for every lesson that effortlessly leads the teacher through the lesson and includes all the answers to the many questions and tasks the students need to complete an editable worksheet for every lesson an easy-to-follow editable lesson plan for every lesson . Not only have you got the complete lessons above but if you wanted to extend the unit I have made it extra easy by also including the Python programs (both with and without comments) for each of these algorithms. I have even created handouts for each algorithm written in pseudocode code using the specifics of OCR, AQA and Edexcel. You could use these Python programs to show the code to the pupils and ask them how it works and talk through the code with them comparing it to the algorithm, you could challenge them to add comments themselves to explain the code or use it to demo a working program. If you feel your pupils are able, you could set them the challenge of programming it themselves and use the completed programs as exemplar material to aid pupils who get stuck or even remove some of the code and ask them to complete key areas to make it work. PRIOR LEARNING This unit does expect pupils know what an algorithm is and be familiar with understanding written algorithms and flowcharts. EASY TO USE These ready to use resources are so straightforward that although I have included a lesson plan, most teachers can teach straight from the PowerPoint presentation without any further assistance. And best of all, the answers are included saving you time and energy. This makes these lessons suitable for experienced computing specialist teachers along with non-specialists and early career teachers. EDITABLE RESOURCES I understand that teachers want to adapt their resources, so I’ve made the bold decision to make these resources editable. Therefore, if you need to use a particular template style for your school or pupils with special educational needs, you can change the PowerPoint presentations, worksheets and lesson plans to suit your needs. These lessons are highly interactive and engage students straight from the start.

HOW CAN I USE THEM? You can use these ready-to-use Python programs and handouts in any number of ways. You could use these Python programs to show the code to the pupils and ask them how it works and talk through the code with them comparing it to the algorithm. You could challenge your students to add comments themselves to explain the code or use it to demo a working program. If you feel your pupils are able, you could set them the challenge of programming it themselves and use the completed programs as exemplar material to aid pupils who get stuck or even remove some of the code and ask them to complete key areas to make it work. You can give them the pseudocode and ask them to write the program from that. . PRIOR LEARNING This unit does expect pupils know what an algorithm is and be familiar with understanding written algorithms and flowcharts. It is also advantageous to have spent some time looking at each of the algorithms (bubble sort, insertion sort, merge sort, linear search and binary search) to only use these programs and handouts as an extension of earlier learning they have done with you to familiarise them with the algorithms and comparison of the algorithms. I have created a unit which includes 3 lessons that can be used to teach your classes about the algorithms. You can find out more about this unit here. #EDITABLE RESOURCES I understand that teachers want to adapt their resources, so I’ve made the bold decision to make these resources editable.

This test is to be given to year 7 pupils to test their current knowledge of key computing areas. This will help you understand their current strengths and weaknesses at the beginning of year 7 and includes a useful spreadsheet which not only highlights pupils understanding but also groups it by class and even primary school to help you inform your feeder schools which areas they need to work on and may need additional help with and which areas they have covered well. The key skills covered in this test are: Word, Excel, PowerPoint, saving files, programming, using the internet, e-safety and computer theory. Due to popular demand, I have interpreted the marks awarded to the old-style level descriptors (i.e. if they score 30 on the test or 45%, this would be equivalent to a 4C).
