Make-and-Take Mini-Units from A to Z l Gr. PreK-1. This resource gives you dozens of ideas for organizing 26 thematic mini-units from A-Z. Each letter of the alphabet is presented as a mini-unit designed to give children practice with fundamental language, math, science, social studies, writing, and thinking skills. Developmentally appropriate games and activities, as well as books, props, snacks, and other items that relate to the theme, are stored in one of several inviting bags or containers that you create from simple, easy-to-find items and personalize with art supplies. These customized containers provide an easy way to manage materials and send them home for children to share with their families.
