We have divided A Crack in the Sea into four sections and created instruction activities for high frequency, Tier 2 words that occur within each section. Each Google Slides presentation contains easy-to-understand definitions, context in and out of the book, synonyms, graphics, part of speech, and various forms for each word. There are also multiple engaging, effective vocabulary activities. We invite you to use these presentations and activities with your students as you teach these vocabulary words in conjunction with the anchor text.
