Imagination is as important as practicality when it comes to kindergartners. Allow your young students to come up with their own range of career options based on what they already know. Have students draw a picture titled "When I Grow Up." Ask them to draw themselves as an adult in a career, be it something realistic, such as a lawyer, or something fanciful, such as a superhero. Help students write a caption under their picture describing what they are doing.
Helping students write a story about their aspirations is one way to expose them to certain career options. Conduct interviews with your students one at a time in which you ask them what their favorite activities and hobbies are. Ask them to think of three jobs that use that hobby. Help them come up with answers if they can't think of any. Help students write a short narrative about their future selves, including what their name is, what they like to do and what they hope to be when they grow up.
Don't be shy about asking parents to contribute to your students' career education. Ask parents to volunteer to come into the class, talk about their career and take questions from students. You can organize them all to come on the same day, or spread the talks out throughout the year. Encourage students to ask questions, and have the class write thank you notes to presenters after they have spoken.
It can be useful to have students brainstorm about all the different career options that are out there. One way to do this is to use their growing knowledge of the alphabet. Each day, take the next letter of the alphabet and have students think of a career that begins with that letter, such as astronaut for "A." Ask students to draw a picture of the career they think of. Keep this activity going throughout the weeks until you run out of letters.
