Grammar Bytes is a website by Robin Simmons, an English and Humanities professor at the Valencia College in Orlando, Florida and a self-described "Grammar Instructor with Attitude." This website contains a wealth of resources for teaching and learning English grammar. These resources include the Daily Grammar Workout - a series of short grammar quizzes that Simmons shares on her Twitter account. Another helpful resource is the terms list: a glossary of terms like "auxiliary verb" and "essential clause." Best of all, Grammar Bytes also features a number of straightforward, interactive grammar exercises that might especially appeal to writing instructors looking for supplementary materials for their classroom. Users can browse these exercises by categories including apostrophes, pronoun agreement, and comma splices & fused sentences. This website also includes presentations, handouts, and links to a series of tips and rules available for download.
