## Introduction

All flash files on this page are copyright, please do not place on other websites without permission. Eventually this page will hold hundreds of flash interactive lesson files. At present there are the 2 files for a Frogs lesson on this page, 8 problems, about 50 starters, 11 probability, 17 statistics and 7 transformations activities on the Tabs above (below if on a mobile).

**If you use Chrome as your browser** then these interactive files might not work (you are instead asked if you want to Keep or Discard the files), then Discard and **go to the link here** and follow the instructions to enable the relevant plugin.
