The fundamental of introductory chemistry is formula writing. The basic requirements of high school chemistry subjects are writing chemical formulas, including writing an ionic formula. Students require good practice and knowledge of the formula and charge of the ions to write the ionic formula and name the ionic compound. A set of cards called “Ancat” consists of the basic atom of the ion on one side, and on the reverse side is the name and formula of the ions. The set of cards comprises the anion and cation cards distinguished by color. High school students would use these cards as a self-directed learning tool. As a selfdirected learning tool, students will construct the ionic formula using the card; then, write the formula and vice-versa. By using the cards, students will be able to identify the symbol of each ion, the charge of each ion, the name of the ions, determine the correct formula of each ionic compound by considering the total charge of an ionic compound is zero, and learn the name of the ionic compound. Teachers can replace the traditional homework with this ductile method that can aid motivation in students; besides that, these cards are suitable for blended learning tools in the classroom.
