JCE classroom activity #113: An interlocking building block activity in writing formulas of ionic compounds
An activity in which students use toy interlocking building blocks to build representations of ionic formulas is described. Students explore cation-to-anion ratios using interlocking toy brick-like blocks to represent trivalent, divalent, and monovalent cations and anions. Students who participated in the building blocks activity showed significantly higher posttest scores than students who had not participated. © 2012 The American Chemical Society and Division of Chemical Education, Inc.
