Reward is a set of general English course books suitable for adults and published by Macmillan. The books are at five different levels: starter, elementary, pre-intermediate, intermediate and upper intermediate.
On the following website is a large selection of free teaching resources that can be used to supplement the Reward course books, or as in my case, used independently. Each activity comes with a worksheet plus teacher’s notes.
Although the course books seem to be aimed at TEFL students, I have used a number of the worksheets with my ESOL students with no or minimal changes.
