1Help your third-grader step up to the next level with confidence. Third grade is a threshold and transition. So much is changing. With number and letter basics locked in, everything--reading, writing, math, science, and more--will expand and ramp up fast. This Big Third Grade workbook is packed with exercises and activities that make the challenges more fun. Sharpen skills that range from punctuation, parts of speech, and persuasive writing to multiplication, equations, estimating, and symmetry. Or work on history, social science, and reading comprehension all at once. Complete a timeline built around a paragraph that tracks the progression from buttons to safety pins and zippers. Then tackle possessive pronouns in sentences that "play detective." Fun facts and "Go For It!" ideas add to the variety. This big book contains hours and hours of creative learning.
