Designed for infusing career development concepts into existing courses or curricula at grades K-3, these learning activities developed by teachers and staff members in the Toledo Public School System cover the following seven developmental areas identified in the Ohio Career Development Continuum: individual and environment; world of work; self; economics; education and training; employability and work adjustment; and vocational decision making. The activities are organized by grade level and then by developmental area. Each activity follows a similar format, which includes broad developmental objectives, more specific behavioral objectives, designated areas for integration, the primary and secondary concepts of the lesson, a description of the activity, a list of media and materials needed, and evaluation.
