## Introduction

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. Mac and Windows instructions are both there: scroll down. **You only have to do this once. **You will need relevant permission to do this on the computer.

Two Frogs Virtual Manipulatives are given below (a main lesson and plenary following from it): they will not work on iPhones or iPads since they are flash files.

## Problems

Each lesson contains a file for the lesson and a linked review session. The notes cover both parts and give objectives, key issues etc. Each line in the table represents a ‘page’ in the flash file.
