The reality
Unexpected absences shouldn't mean chaos
When you're called away with no warning, the pressure to leave something useful behind is real. These are the moments most teachers aren't prepared for.
No time to prepare anything useful
A family emergency or sudden illness means you have minutes, not hours. Writing a coherent lesson plan from scratch simply isn't possible in that window.
Generic plans that subs can't execute
Downloaded sub plans rarely match your topic, year group, or student needs — leaving substitutes guessing and students disengaged.
Curriculum gaps when you're away
Days without a proper structured lesson mean lost instructional time and standards coverage that is hard to recover when you return.
Everything your sub needs to walk in ready
Chalkie gives substitute teachers and department heads everything required for a smooth, no-prep lesson. Here are the tools built for exactly this situation.
