Fast Math is not about giving students more worksheets and hoping repetition makes them faster. Your job is to find exactly what prevents students from developing math fluency, then use AI to rebuild the learning experience until accurate calculation becomes automatic.
2 Hour Learning helps students learn core academics in a fraction of the normal school day. You will focus on our Fast Math program, using student performance data, platform data, assessment results, and student work to identify what is blocking fluency and fact mastery. The problem might be weak sequencing, the wrong practice pattern, a missing scaffold, poor feedback, or an intervention that fails to correct the underlying misconception.
This is hands-on work. You will use LLMs, AI-assisted content generation, no-code workflows, and agentic AI tools to improve practice sequences, explanations, assessments, scaffolds, and interventions. Your work succeeds when students move from effortful calculation to fast, accurate, automatic performance. If you want to use AI every day to make measurable gains in mathematical fluency, apply now.
Accelerate K-12 math fluency by continuously improving Fast Math curriculum, practice, assessments, scaffolds, and interventions until students calculate accurately and automatically.
Crossover's skill assessment process combines innovative AI power with decades of human research, to take the guesswork, human bias, and pointless filters out of recruiting high-performing teams.
