A checklist for teachers of English as a Second Language who are teaching the expression of comparisons is presented. It is intended to assist in the systematic classroom presentation of features of comparison, with adaptation for any proficiency level. Broadly, it addresses how both the units being compared and the points of comparison need to be treated. More specifically, it addresses the treatment of syntactic, lexical, arrangement, rhetorical, and logical features of the comparison. Notes on the usage of these features, and the kinds of problems students often have with them, are presented alongside the teaching information. A student handout and sample class exercises are included. (MSE) (Adjunct ERIC Clearinghouse for ESL Literacy Education)
