The CLR Toolkit aims to provide resources for groups wishing to get started on, and sustain lesson study.  There are two sections to the toolkit:

The starting point of this lesson was the Outbreak lesson sequence from the Bowland website The task concerns an infectious disease spreading within a city under quarantine. Two vaccinations exist, and students are given their costs and percentage effectiveness, and told that a budget of £5m is available. Students are asked to recommend how many of each vaccine should be made and who should get them.
