This booklet contains 43 "workjobs," (experiences in manipulating common objects) adapted from classroom activities, that are appropriate and easy for parents to make and use with children in the home. These manipulative activities are designed to help children develop language and number skills and hand-eye coordination, and give children practice in making observations, identifying relationships, and making judgments. All the activities have similar formats including a description of the activity and the skills to be developed, hints for getting started, ideas for follow-up questions, a photograph of the child involved in the activity, and a list of common, inexpensive materials to be used. A general introduction provides parents with a rationale for using the workjobs and discusses such parental concerns as the best uses of the activities, age-appropriateness, the establishment of the parent-child relationship, the importance of follow-up, and problems of storage.
