Paws in Jobland is a free online website created by Bridges Transitions Inc. The career inventory on the website asks students a series of questions about things they like to do, things they are good at, or things they are interested in, and then presents the students with a list of jobs that they may enjoy. Students can explore jobs they may be interested in on the website by clicking on different buildings in "Jobland". Videos explain responsibilities for different jobs and show real people doing them. There's also a fun multiple choice game that challenges students' knowledge about various jobs. As an added bonus, the program reads the questions and gives directions out loud for students who are not strong readers. There are also supporting worksheets and lesson plans to go along with it.
I'm thinking about using this with my 3rd graders. :)
