The first section of the new Interactive Tutorial section teaches you how to form basic sentences using adjectives and the present tense of ser and estar. The tutorials feature interactive "fridge magnets" exercises that allow you to practise forming sentences and aim to give feedback appropriate to your answers.
More tutorials using a similar style are in the pipeline. If you have any feedback on the adjectives tutorial, then please feel free to leave comments on this entry. We're particularly keen to hear from people using the "fridge magnets" exercises on a touch screen or interactive whiteboard.
