ITPs for modern times

Old folk like me will probably remember the National Numeracy Strategy (NNS) Interactive Teaching Programmes (ITPs) – some of which were great and some of which were horrible.

It turns out, they were great tools to show loads of mathematical ideas on whiteboards – but because they were made in the late 90s, and in Flash, lots of them no longer work.

Ted Burch of has very kindly remade them all in html5 but retained their original look.’s ITP Polygon

The reworked programmes should work on tablets and most modern devices.

All 25 of the Maths Frame ITPs.

There are currently 25 remade tools which are all available for free here:


Free Download: Mathematical Vocabulary Flashcards

The following ten files are a straightforward set of mathematical vocabulary flashcards. I have grouped them by topic and have written on in small lettering where in the curriculum the term is introduced.

A sample page from the addition and subtraction group is shown below. All of the pages share the same design.

Page 1 of “Addition and subtraction vocabulary.pdf”

Feel free to share with colleagues – I would love to know how they are being used.

Tessellation: M.C. Escher – Metamorphosis Machine

The work of M.C. Escher is full of tessellation and he was inspired – he referred to a ‘mania’ he had – to fill a page with shapes.

With this site, you can make your own metamorphosis and techniques which Escher developed by hand over the years are built into the ‘Metamorphosis Machine’.

The Metamorphosis Machine:

Children can make their own Escher work and become part of the endless metamorphosis.
