Warm Up to Science: TEKS-Based Engagement Activities Series incorporates instructional strategies that enhance student achievement. Each book in the Warm Up to Science series offers teachers 100 classroom-ready engagement activities for immediate student involvement in one or more of the specific concepts and processes that are identified by the TEKS. Individual activities may be used as an engagement for a new lesson, as a method to enhance retention, or as a formative assessment within a lesson. Designed to require five to ten minutes of instructional time, the activities focus on items that are content-specific or items requiring the interpretation of nonlinguistic stimuli such as in diagrams, charts, graphs, and tables.
