Third-grade teachers from eligible schools will (1) examine TEKS-based learning progressions and critical checkpoints for student understanding and (2) experience classroom-ready activities, including formative assessment and follow-up activities that account for learner variability. Teachers will build a toolkit of strategies and key questions for students with disabilities, English language learners, students struggling to learn mathematics, and gifted learners. Structures that provide opportunities for meaningful practice and feedback will be explored. With hands-on activities focusing on grade-level TEKS, this academy is designed to strengthen teachers' knowledge of mathematics concepts and processes, improve overall mathematics instruction, and support student success. Upon successful completion, eligible third-grade teachers will receive a stipend.
