Random Spinning Name Selector (Wheel of Fortune)

Random Spinning Name Selector (Wheel of Fortune)

(94)
A PowerPoint slide that can be dropped into any presentation, or used as a standalone resource. It looks and works a little like the Wheel of Fortune game show, with student names on a wheel that can be sent to spin, and then stop randomly at any point to choose a random student. Sound effects and music included, it is extremely easy to edit the student names. I suggest creating one slide per class. If you have any questions or comments please do let me know.

Making Connections Game - Cross Topic Revision Activity (Easily Customisable)

Making Connections Game - Cross Topic Revision Activity (Easily Customisable)

(1)
This is an excellent little resource for getting students to make connections between topics and ideas which might not naturally occur to them, improving fluency and mastery within any subject. The idea of the game is simple: the teacher simply clicks the orange 'Go' button and the computer randomly selects two different words from a word list set by the teacher. The students are then challenged to devise a sentence which uses both of the two words in it, creating a connection between them. In some cases this may be easy ('input', 'mouse', but at other times they will have to extend their thinking to reach across apparently distinct topic areas to identify a connection or relationship ('binary', 'wireless'.) The game is very easy to customise. It consists of two files - a PowerPoint file, and a plain text file called 'words'. The plain text file called 'words' can easily be edited to contain any word list you choose, and is therefore both subject and topic independent. You could have several word lists prepared for different topics or classes, and just swap the 'words' file over when you need it. As long as the 'words' text file and the PowerPoint file are kept in the same folder, the game will work. The example provided contains a GCSE Computing keyword list, but this can easily be changed or adapted to suit your needs.

jsarnoldjsarnold

Binary Code Icon Worksheets (8 x Worksheets)

(1)
Fun, but challenging worksheets for students studying binary code and encoding bitmap images. Each of the 8 sheets includes both answer sheet and a worksheet. The answer sheet shows a set of 4 different 8 x 8 bit icons, with the decimal equivalent of the binary representation for each row shown on the left. Students need to convert the decimal value into binary, and then fill in the pixels for that row accordingly, eventually generating the icon image. With a set of 8 worksheets, each featuring 4 different images, this set provided 32 activities. Both student worksheets and clear answer sheets for the teacher are included.

"Mindcraft" - Easily Customised PowerPoint Class Quiz With Minecraft Theme

"Mindcraft" - Easily Customised PowerPoint Class Quiz With Minecraft Theme

(0)
Developed in PowerPoint using VBA this extremely versatile and very popular Minecraft inspired activity can be used as a starter, plenary or other whole class or group activity that aims to get children collaborating, discussing topics and working together as a team to consolidate their knowledge and understanding of any topic you choose. Easily create your own lists of questions using nothing more than Notepad (or similar text editor) and then simply drop whichever question list you want to use into the same folder as the Mindcraft file, and it will immediately shuffle up your questions and use them to stretch your students' knowledge. The rules are simple and explained clearly within the activity, but essentially students will be divided into two teams, and each team will be able to 'mine' their way through a virtual Minecraft style world. They'll come across dirt, stones, iron, coal, gold, emerald, water and even creepers! Each item type will result in different actions being taken. Finding dirt or stone will require a question to be answered, whereas gold and other valuable ores will earn the team points. Getting questions right also earns points, but getting them wrong will lose points. Find a creeper and the loud explosion will signal that team's turn over! Watch a video demonstration of this resource, as well as a clear tutorial on how to use it, and adapt it: https://youtu.be/fmzzSwc3ATM
