Make factor trees, number lines, force diagrams, and Bohr atom models for clear, printable learning materials.
Use Factor Tree for prime factorization and GCF or LCM comparisons. Number Line shows values, fractions, and intervals; Free Body Diagram labels forces acting on an object. Bohr Model Maker shows an atom's electron shells, particle counts, isotopes, and supported ions.
Build a visual factor tree, compare valid factor pairs, and print a prime factorization worksheet.
Set the range and tick interval, plot fractions or inequality intervals, and make a blank worksheet with its answer key. Preview instantly and export without signing up.
Draw exact force vectors, calculate components and net force, check the setup, and export SVG or PNG.
Choose an element, inspect electron shells and particle counts, compare isotopes or ions, and download SVG or PNG.
