xElements is a program for generating Bohr diagrams of elements. These diagrams are frequently used in high school science courses to introduce students to the atoms and ions of the various elements. This program will automatically generate different isotopes and ions of the first 20 elements (the ones that work with the "octet rule"), which can then be exported, copied, or dragged into other applications such as iWork (Pages, Numbers, and Keynote), OmniGraffle, Microsoft Word, Powerpoint, etc.

xNumberLines is a program for generating number lines with solution sets to algebraic problems (such as inequalities). These diagrams are frequently used in middle school and high school math courses. This program will automatically generate the graphical solution diagrams when you input algebraic expressions such as "x < 3" or "-2 <= x < 4". The diagrams can then be exported, copied, or dragged into other applications such as iWork (Pages, Numbers, and Keynote), OmniGraffle, Microsoft Word, Powerpoint, etc.
