Made for a colleague in Modern Foreign Languages Dept. This Excel Worksheet changes a regular 9x9 SuDoku puzzle in a newspaper from numbers to words. You choose the 9 Themed Words and Vocabulary in the target language (e.g. Animals, Colours, Christmas etc.) and the word puzzle is created as you enter the puzzle numbers. Two copies of the puzzle are printed on a single A4 page, with the list of the 9 words down one side. Adaptable to other Languages.
A checklist of 50 I can do this statements designed to cover the Edexcel syllabus for students revising. Answers not provided - they are for the students to research - but The Big 50 does provide a useful framework. Modules here: C1, C2, C3, M1, S1, as well as GCSE Statistics.
Here’s a quick puzzle to use as a warm-up to any Maths or Numeracy lesson. The aim is simply to order the numbers 1 to 9, but the real skill comes in doing it in the fewest moves! Accessible to Primary and Secondary age students. There are different strategies to discover to achieve Brilliant! or Genius each time. How quickly can you become a Reverser Expert? Tutorial now added to help you enable Macros in Excel if this is new to you.
NEW: Some users seem to be having difficulty opening this large file. It is a text file. The first line has '3.' The second line begins '14159...' as expected. There is no 3.014159 as some claim :-)
A large text file consisting simply of the first million digits of Pi. The digits are arranged in rows of 50 digits per row, beginning with the 1 after the decimal point. You’ll be delighted to know that the millionth decimal place is a 1 as well.
A sketch that could be used with KS3 to present issues related to personal hygiene in a humorous way. There are four contestants, and the 'Weakest Stink' (the cleanest) is eliminated at the end of each of three rounds, leaving one repulsively smelly champion.
Simple staging could involve a music stand or similar to hold each contestant's script and this could be decorated with the programme's logo (design your own!) at the front. Written for female quizmaster and four male contestants but contestants 2 and 3 could easily be girls Duration about 5-6 minutes.
A pictorial guide for invigilators of Mathematics examinations, showing the commonly used calculators, all of which are acceptable for use, and some examples of the more sophisticated machines which are not acceptable.
A simple scorer for a Quiz Night or Classroom Team Quiz. Up to 16 teams and 12 rounds. When a team plays their joker they automatically score double points. The winning team is always highlighted. Instructions included and questions based on various KS3 topics. This is an excellent classroom activity that is suitable to be used as a plenary.

Look up the Bible references to solve the clues and then find the answer in the wordsearch. BibleGateway is a good place to look if you don’t have a physical Bible. Digital Bibles are also available for all tablets and smartphones.

Created using WordSearch 4 for Mac by Jim Graham.
A test for those about to enrol on Year 12 Maths courses to see if they could cope. Contains topics drawn only from Higher Tier GCSE, including manipulation of fractions, index laws, surds and quadratics. Detailed Mark Scheme provided too.
Created by our KS5 Co-Ordinator Mr B and highly recommended by the whole department.
A probability modelling exercise using two dice. The original pair of birds will lay between 4 and 16 eggs (according to the dice outcome described), and each egg is then submitted to the chances of nature as it struggles to hatch, develop and reach adulthood. How many of your chicks will survive to become breeding adults themselves?
Experience has shown that this can easily absorb students for up to an hour, and talk about the task soon has other students asking to do it! You only need two dice and this sheet to play the game, and even if you have no dice you can still use the Random Number generator on your calculator.
At each stage you shade in the boxes in the grid to show success, and fill in an X where the egg/chick fails to thrive. Students become highly invested in looking out for their eggs and chicks, commonly giving them names and mourning their demise!
Good to gather collective experimental data at the end.
A browser-based version of the classic Blockbusters Game, with configurable board size. Two game modes: Hex Game (alternating colours) and Winner Stays On.
Bring tension, teamwork and drama into your classroom with this fast-paced, whole-class quiz game inspired by the iconic TV show and the famous Hex strategy game.
Hex Game mode
Based on the original Hex Game (invented by Piet Hein and popularised by John Nash and Martin Gardner), teams take turns to claim tiles.
• Blue’s goal: connect Top to Bottom
• Red’s goal: connect Left to Right
• With perfect information and no luck involved, the game cannot end in a draw
Blockbusters (Winner Stays On) mode
Correct answers keep your team in control!
• A correct answer lets your team colour a tile and take another question
• A wrong answer hands control to the opposing team (with no tile claimed)
• Ideal for escalating difficulty, pressure, and excitement as streaks build
Use any questions you like – subject knowledge, retrieval practice, revision, or general knowledge – and increase the challenge when a team stays on to ramp up the drama.
The game runs entirely in the browser with no installation required.
You can even personalise the experience: simply edit Line 15 of the HTML file in a text editor to change the on-screen title to your own name.
Perfect for revision lessons, end-of-term fun, or injecting competitive energy into learning.
Number Bingo (1–31) – a simple, focused lesson finisher
This PowerPoint is a no-frills Bingo resource consisting solely of the numbers 1 to 31, each displayed clearly in a large font. Students pick their own set of 6 numbers (from 1 to 31) and the PPT then “calls” the numbers.
It is deliberately simple.
What it’s good for:
• Number recognition – particularly helpful for younger students or those who benefit from extra fluency practice
• Speed and concentration – students must stay alert as numbers appear quickly and unpredictably
• Calm, purposeful endings – an easy way to keep attention right up to the bell
• Zero cognitive clutter – nothing to decode, explain or interpret
This works well as:
• a 5-minute end-of-lesson activity
• a settling task
• a cover lesson standby
• or a gentle, structured way to finish when time is short
There are no questions, tricks or hidden objectives here — just clear numbers, fast recognition, and sustained focus.
Free to use and adapt. Contains a Macro to shuffle the numbers.
