Random Spinning Name Selector (Wheel of Fortune)

A PowerPoint slide that can be dropped into any presentation, or used as a standalone resource.

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.

"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
