Just what it says on the label. Modals I is pure explanation, Modals II comes with exercises. Useful.
A new sheet on my favourite verbs -I find this one even more useful than the other two. It comes in a table format: To express ... Use ... . Examples: ... . Check it out!
A work sheet / fact sheet on ...correct. Soon to be followed up by others.
The second of this new series. The topic should be clear from the title.
Number three of the series on modal verbs by meaning. The exercises are tricky -still, using the fact sheet part of the paper, you should do just fine.
The one that was indeed planned to be number four of the series. Once more, this one comes with a fact sheet and a work sheet.
This one was originally not planned to be the fourth paper of the series, but to come in somewhat later. As the others, this paper comes with a factfile part and exercises.
