Please note: the Excel spreadsheet is protected and only some cells are open for the pupils to type into.

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.
