The Grammar You Need series (three levels) covers essential grammar
for the purpose of writing in English in an academic setting. Each
fold-out card provides clear, full-color visuals showing how the grammar
structures work and how to apply them. Students can download free
workbooks from ProLinguaLearning.com and can also take advantage of the
powerful web application for this series at TheGrammarYouNeed.com.
Level 2 of the series, Developing Details, develops students' skills
in adding details to nouns, expressing ideas with verbs, writing with
sentence variety, using passive voice, stating facts, predictions, and
hypotheses, and more.
