- Explicit and daily phonics and read-aloud routines where students learn to decode words, grow their vocabulary, and build comprehension through Amplify CKLA; students begin writing complete sentences and short stories.
- Problem-based approach to math through Illustrative Math, building a strong foundation in number sense by solving real-world problems with hands-on tools.
- Science, Technology, Engineering, Art & Math (STEAM) through Project Lead the Way; students investigate motion, sound, and structure by constructing simple models, asking questions, and recording observations through early engineering and science practices.
- Social Studies program aligns with literacy units to enhance students' understanding of leaders, rules, and responsibilities, understanding how people and events shape the world around them.
2nd Grade
- Structured and explicit literacy instruction with differentiated practices providing students with strong foundational skills through Amplify CKLA; includes informational and narrative reading with guided writing in complete paragraphs.
- Problem-based approach to math through Illustrative Math, extending fluency with addition and subtraction and develop conceptual understanding of early multiplication through hands-on, problem-based tasks.
- Science, Technology, Engineering, Art & Math (STEAM) through Project Lead the Way, where students design and test simple tools, explore materials and their uses, and participate in engineering challenges through structured design cycles and collaborative group tasks.
- Social Studies program aligns with literacy units to enhance students' understanding of the world while learning how people, places, and ideas connect across time and cultures.
3rd Grade
- Close reading of complex texts and practice structured writing with topic sentences, evidence, and revision strategies through Amplify CKLA.
- Problem-based approach to math through Illustrative Math, building fluency with multiplication and division skills and deepen understanding of fractions, area, and data using problem-based learning and student discourse.
- Science, Technology, Engineering, Art & Math (STEAM) through Project Lead the Way, engaging students in hands-on, interdisciplinary projects that emphasizing critical thinking, problem-solving, collaboration, and creativity.
- Social Studies explore key historical and civic concepts; focused on US government and the importance of communities.
4th Grade
- Application of advanced reading strategies to synthesize information across texts; expanded vocabulary and structured writing tasks including opinion, information, and research-based compositions through Amplify CKLA.
- Problem-based approach to math through Illustrative Math, where students develop proficiency with multi-digit multiplication/division, and deepen understanding of fractions and geometry through multi-step, real-world problem solving.
- Science, Technology, Engineering, Art & Math (STEAM) through Project Lead the Way, where students engage in projects applying data analysis, digital tools, and scientific reasoning to propose and present solutions.
- Students explore Texas history, including Native peoples, colonization, independence, and statehood; analyze maps, governmental structure, and civic duties.
