Ionic Blocks  Richard S. Sevcik, Rex Gamble, Elizabet Martinez, Linda D. Schultz, and Susan V. Alexander
"Ionic Blocks" is a teaching tool designed to help middle school students visualize the concepts of ions, ionic compounds, and stoichiometry. It can also assist high school students in reviewing their subject mastery.

The Use of Extent of Reaction in Introductory Courses  Sebastian G. Canagaratna
This article discusses the use of the extent of reaction as an alternative to the traditional approach to stoichiometry in first-year chemistry. The method focuses attention on the reaction as a whole rather than on pairs of reagents as in the traditional approach. The balanced equation is used as the unit of change.

Using Games To Teach Chemistry. 2. CHeMoVEr Board Game  Jeanne V. Russell
A board game similar to Sorry or Parcheesi was developed. Students must answer chemistry questions correctly to move their game piece around the board. Card decks contain questions on balancing equations, identifying the types of equations, and predicting products from given reactants.

The chemical equation. Part I: Simple reactions  Kolb, Doris
A chemical equation is often misunderstood by students as an "equation" that is used in chemistry. However, a more accurate description is that it is a concise statement describing a chemical reaction expressed in chemical symbolism.

Gram equivalent weights  Meldrum, William B.
The purpose of this paper is to review briefly the subject of equivalent weights and the more directly applicable gram equivalents and to offer a general method by which they may be deduced from chemical equations.

On accenting observations in chemistry  Campbell, J. A.
A chemical equations is, for many a student, such a complete abstraction that he would be hard put to describe the actual observations that would be made in a process for which he was supplied the complete equation.
