This document describes how to teach grammar using board races. It suggests writing adjectives on a board with columns for "er" and "more" forms. Students are split into teams to write the comparative forms in the correct columns. This engages students actively in the lesson and improves the classroom atmosphere by avoiding boredom. The technique can also be used to teach other grammar topics like verb tenses, conjugations, and irregular verbs. Board races create a fun challenge that keeps students interested in learning grammar.
