Great idea! Why don't we put together about 5 essays from each author? Each essay must have corresponding grammar and vocabulary attacks, exercises and games...What do you think? I suggest each text to have tests that would cater to various levels: adult 800 plus level, 600--to 400, then HS intermediate to advanced, junor high beginner level, etc. This way, ALTs could use the other exercises they find easy to their students. I am tired of thinking various different ways of introducing lessons in challenging and enjoyable ways. I need some support from other writers.
I have recommended to them Baron's TOEIC review as it contains about 100 pages of grammar and vocab.review and 600 pages of tests (with answers explained in detail). That book costs 2,100 yen (1,100 pesos), but charging them 1000 yen, half that thick of a book would still be reasonable. I now have a laser b/w printer/copier, so I think it would be good to start soon. I do the printing, you supply me half of the material. Deal? How much do you charge per material?
