OCS.math.3.4a: Solve problems using models, pictures, words, and numbers

In this engaging resource, students take on the role of Math Detectives to solve multiplication and division word problems as they work to uncover clues regarding missing items at a Classroom Carnival. The learning objectives emphasize interpreting multiplication as groups of items and solving word problems within 100, using various strategies such as models, pictures, and equations. Through a series of mystery clues related to ticket counts, rubber duck sorting, prize display puzzles, and balloon distribution, students are guided from worked examples to collaborative practice and finally to independent problem-solving. The document provides a structured approach to understanding multiplication and division, integrating fun scenarios to motivate students while reinforcing their critical thinking skills.
