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.

A great introduction to understanding how text, images and sound are saved as binary. These ready to use data representation 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: ASCII characters Bitmap images Sound . Everything you need is included 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 a 2-sided editable worksheet for every lesson an easy-to-follow editable lesson plan for every lesson . PRIOR LEARNING This unit does expect pupils to be familiar with binary and in particular know that: Computers store numbers using binary. Binary can only contain 1s and 0s. A single binary digit is a bit. They can translate denary numbers into binary and binary numbers into denary by working out the column headings. . If your students are unfamiliar with these concepts, I highly recommend purchasing my 2 lesson unit called “Understanding Binary” which covers all of these topics and will ensure your students are ready for this unit. Many teachers purchase both units (Understanding Binary and Data Representation) together and run them as a single 5 week unit as they complement each other so well. 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 (ECTs). 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 if you have students with specific educational needs, you can change the lesson to suit them. It gives you the flexibility to alter the lessons to suit your own particular needs. SCIENTIFICALLY PROVEN TEACHING TECHNIQUES These teaching resources have been specifically designed to aid pupils using educational psychology backed theories including dual coding, Mayer’s theory and the best techniques to alleviate cognitive load. Your students will have a higher retention rate, better and deeper understanding of the subject matter and will build their confidence in a natural way which reduces distractions and helps them focus on the learning. These lessons are highly interactive and engage students straight from the start. Just click on the BUY NOW button to download them straight away. You’ll wonder how you ever managed without them.
