Fast Math does not rely on endless worksheets or the assumption that repetition alone builds speed. Your role is to pinpoint the exact barriers that prevent students from achieving math fluency, then leverage AI to redesign the learning experience so that accurate calculation becomes automatic.
2 Hour Learning enables students to master core academics in far less time than a traditional school day. You will concentrate on our Fast Math program, analyzing student performance data, platform metrics, assessment outcomes, and student work to uncover what is inhibiting fluency and fact mastery. The obstacle may be inadequate sequencing, an ineffective practice structure, a missing scaffold, insufficient feedback, or an intervention that does not address the root misconception.
This role is hands-on. You will apply LLMs, AI-assisted content generation, no-code workflows, and agentic AI tools to enhance practice sequences, explanations, assessments, scaffolds, and interventions. Success is achieved when students transition from labored calculation to fast, accurate, automatic performance. If you are ready to use AI daily to produce measurable improvements in mathematical fluency, apply now.
Accelerate K-12 math fluency by continuously refining Fast Math curriculum, practice, assessments, scaffolds, and interventions until students calculate accurately and automatically.
