From site: Among the proven techniques for improving test scores is regular exposure to skills that will be required for those tests. Daily exposure to language skills -- including skills of spelling, capitalization, punctuation, and grammar -- will build students' skills and increase test scores.
That's why Education World has introduced Every-Day Edits, a feature that provides daily practice in a wide variety of basic language skills. Each day, we provide a paragraph with ten built-in errors of basic spelling, grammar, punctuation, or capitalization. Send students on a hunting expedition, then review the work with them. This daily exposure is sure to cement some very important skills as it lays the foundation for improving students' test scores.
