Built For Problems, Not Just Text
The parts of maths teaching that other lesson tools get wrong.
Numeric answers with tolerance
Accept 3.14 or 3.1416 — set how precise the answer has to be and let it grade automatically.
Formulas that render properly
Mathematical notation displays as notation, not as broken plain text.
Infinite whiteboard
Work through a derivation step by step with pen, shapes and arrows while the student watches.
Student solves on the board
Hand the pen over — let the student work the problem while you follow along live.
Sort into categories
Classify functions, shapes or number types with the arrange-by-columns exercise.
Step ordering
Give the steps of a proof out of order and make the student sequence them correctly.
Less Marking, More Teaching
Set the drilling to run on its own and keep your time for the explaining.
Homework marks itself
Numeric and multiple-choice problems grade on submission — you see only what needs attention.
Reuse problem sets
Build a sheet once and assign it to every student who reaches that topic.
Keep the worked examples
Whiteboards are saved, so last month's explanation is one search away.
See who is stuck
Completion and performance per student, so you spot the gap before the exam does.
Diagrams on demand
Drop an image onto the board and annotate directly on top of it.
One room for everything
Video, problem sheet and whiteboard side by side — no screen sharing needed.
