Fun with Formulas
Materials Required: Teacher prepared “dice” with ions printed on each side (2)
Activity Time: Varies according to class
Concepts Taught: Practice writing formulas/naming compounds
Have students divide into groups of two. Each one picks
a different color dice. Each dice has either positive ions
or negative ions. Students roll the dice and write the
correct formula using the valences and/or write the
correct name. Can be as many combinations as you are willing
to make dice. Key is a grid with positive ions across
the top and negatives down the side. Correct answer is located
where the coordinates meet.
