Numernabis puts the whole maths problem on one board

Field notes

The workspace keeps the problem statement, handwritten calculations, diagrams, files, and assistant conversation together instead of requiring the learner to retype work elsewhere. The displayed quadratic example moves from identifying the vertex to checking zeroes, while the geometry module describes models that can be rotated and viewed with selected edges, diagonals, heights, and angles. The site also advertises photo and PDF input, saved boards, activity history, and shared boards for one-to-one lessons.
