Go to eflclassroom2.0.com and on the home page you will find Lessons in a Can. I think there are 100 of them on all levels. They are in English but just change the language. At least it will give you some ideas to get you started. I love Big Town and Little Town.
you can have them read a paragraph and let them record it so they can go back and listen to what they need to pronounce more. You can also get them in groups of 2 or 3 and have them make up a mini dialog. It will be fun for them to figure out a story and at the same time, they will be practicing it. You can also give them a tongue twister in spanish of course and let them recite it to you. I hope you find a good way to have them speaking spanish.
