Variety of resources for pi day activities. Updated April 2016. Includes links to classic video on history of pi and to excellent Numberphile pi videos. Also find more famous people as well as Einstein and Michael Caine who were born on pi day. A few active lesson plans taken from great Illuminations site. Finally cannot forget to include 1,000,000 digits of pi and the Freehand Circle Drawing activity! Enjoy. Links to IWB file for ActivInspire.

Variety of resources for work on BMI. Includes history, BMI calculators from NHS, BBC, US source plus charts, tables and graphs as well as information about a suggested new ‘better’ formula (from news article of January 2013). NHS links and charts linked to healthy living also present. Links to IWB files (ActivStudio, ActivInspire and Smart Notebook 11) can be found in the file, plus all other links. Enjoy (updated 6 October 2015).

Updated 12 October 2020. This lesson on body maths is about scatter graphs: looking at the work of Claudia Zaslavsky (Africa Counts – excellent book on mathematics from Africa) to introduce the Chagga people of Tanzania. Other links are made to Vitruvius, Leonardo da Vinci and the fathom. All you need is included in the ActivInpire, PowerPoint and Excel files that can be accessed from this file. Excel file allows input of pupil measurements that can collected at home (for Covid times) and will then create automatically scatter graphs. Worksheets included in this file.[https://spiremaths.co.uk/bmscatter/]

A Spiremaths set of resources that include videos, interactives, revision sources, historical information, and an active lesson plan related to making this aspect of curriculum stimulating, interesting and relevant. Also supplied are links to National Centre for Excellence in the Teaching of Mathematics Departmental Workshop on Index numbers (not all links work in this). Links to IWB files for ActivInspire and Notebook 11 are provided. Links in this document correct as of early November 2015.

Two or three lessons where pupils investigate the locus of a snooker ball around a ‘table’.It is primarily about factors (co-prime and highest common factor, HCF) but charting activity extends it making it good for getting pupils to explore mathematics, use reasoning and examine proof. Provides links to ActivStudio, ActivInspire, and Smart Notebook files as well as an Excel spreadsheet I put together to produce answers and charts. Links to original source material as well.

Make a giant class ‘fractal’ tetrahedron with balloons. Work out how many balloons you need to make this tetrahedron. Work out which of the Platonic solids can be made with a single balloon! Use fractions and ratio and proportion to decide the proportions of a balloon dog. File contains links to IWB file for Promethean and Smart.

Nine grids are hidden behind ‘cards’. The grids comprise the 100 square (numbers not shown) with some cells shaded in red. Each grid is displayed for one second. Pupils have to work out what is shown in each grid. Most show sequences of some form. IWB files are available for Promethean and Smart.

This is a revision lesson on circle theorems for 14-16 year olds, but could be used with other pupils as well. It is based on an MEI item of the month (January 2010). IWB resources are available for the lesson: ActivStudio, ActivInspire and Smart Notebook 11 (see file ). I am not aware of a world championship after 2007 - but who knows!

The well-known frogs activity - with much more: ideal for the new curriculum. Solve (hints shown to key steps), a link to a proof, investigate to create graphs from tables of values. Links to an ActivInspire source for those with Promethean boards; an excel version for those without and even a flash activity. Best for KS3/4, but aspects could be used at KS2. Have fun.

Links to IWB versions of the Improving Learning in Mathematics (Standards Box) materials, including links to some of small software packages used in the original materials. Updated links for October 2015. Flipcharts work in ActivStudio, ActivInspire and Smart Notebook 11 at this time.

I have two counters and each have a number written on each side. When I place the two counters on a table I can add the numbers to make a total. If I can make totals of 15, 16, 17 and 18 what numbers can be on the counters. Full information, IWB files and answers. Adapted from Shell Centre's Problems with Patterns and Numbers.

The 66 cross numbers (crosswords with numbers as answers) in this book are mostly arranged in order of difficulty. The cross numbers can be used in a number of different ways, which would allow pupils to practise or develop different skills. They require logical thinking as clues are interlinked. You need to decide where to start. Free to photocopy but please acknowledge. All answers now included in this version of the book. The early cross numbers can provide practice of basic addition, subtraction and multiplication, though they can also be used to provide calculator work. Some of the more difficult cross numbers require the use of a calculator or spreadsheet. In all cases, most of the answers are cross referenced to other answers in the cross number. Where this is not the case the answers come from one of several categories: time conversions metric conversions miscellaneous conversions You will need to ensure that pupils know about these conversions (especially the meaning of gross, score and decade). Later on pupils will need to know about primes, squares and cubes. Finally, comes the introduction of factors and multiples.
