Third-grade teachers 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 by analyzing activities for students with disabilities, learners who seek to be bilingual and bi-literate, students struggling to learn mathematics, and learners identified for gifted services. 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.
