Watch out for the monsters! In this workbook, you'll learn how to use bar models to solve addition problems. Read each question and figure out how many frozen treats these hungry monsters gobbled up!

In second grade, using bar models to teach addition is highly effective because it provides a clear and visual representation of numerical relationships, making abstract concepts more concrete for young learners. Bar models help students quickly grasp the concept of part-whole relationships by visually breaking down numbers into manageable segments. This method supports the development of number sense, allowing students to see how different numbers combine to form sums.
