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.

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.

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.

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.
