Mathematics Learning Specialist at IThrive Math (2015-01 – Present)
- Design and deliver standards-aligned mathematics intervention programs for Grades 3–10, supporting 100+ students annually with diverse learning needs.
- Develop scaffolded lesson sequences, differentiated practice sets, and targeted formative assessments informed by diagnostic data.
- Created "Ditch the Fingers," an accelerated numeracy intervention (Grades 3–5) using the CRA framework—moving students from concrete manipulatives (bead strings) to visual models (number lines) to abstract mental strategies within 6–12 weeks, achieving a 100% success rate in transitioning students from counting-based to flexible mental computation.
- Design multi-step learning progressions for fractions and geometry using concrete, semi-concrete, and abstract representations; integrate real-world problem-solving tasks to deepen mathematical reasoning.
- Leverage AI tools (ChatGPT, Claude, Gemini) to generate, refine, and validate lesson content, problem sets, and differentiated tasks, improving efficiency and content quality.
- Align intervention design with international best practices and U.S. learning progression frameworks.
