The best online whiteboard for math

Work Through Equations and Problems by Hand
Math is best learned by doing, and Jotboard’s pen tool turns any device into a freehand writing surface where you can work through equations step by step. Write out a problem, show each line of working, and use the eraser to correct mistakes along the way, just like a physical whiteboard but with the added benefit of saving your work automatically. Teachers can prepare problems in advance on separate slides and have students solve them live during a lesson, while students can use the board independently to practice and review. The ability to use different pen colors makes it easy to highlight important steps, distinguish between given information and derived results, or color-code different parts of an equation.
Draw Graphs, Diagrams, and Geometric Figures
Many areas of math rely heavily on visual representations, from plotting functions on coordinate planes to constructing geometric proofs. Jotboard’s drawing tools and shape library let you sketch graphs, draw angles, construct triangles, and illustrate transformations directly on the board. Use the straight-line shape tool for axes and precise constructions, then switch to the freehand pen for curves and annotations. Drop in images of printed graphs or textbook diagrams using the image tool, and annotate them with highlights and notes. The slide-based interface means you can dedicate one slide to algebra, another to geometry, and another to statistics, keeping each topic neatly organized.
Collaborate on Problem Solving in Real Time
Whether it is a teacher working with a class, a tutor with a student, or a study group tackling homework together, Jotboard makes collaborative math sessions straightforward. Everyone on the board can write, draw, and type at the same time, so a tutor can guide a student through a problem while the student shows their own working on the same slide. Import worksheets and practice sets as PDFs so everyone is looking at the same material, and export the completed board afterward as a study resource. The free plan supports up to five collaborators, ideal for small groups and tutoring, while the paid plan at four dollars a month opens collaboration to an entire classroom.
