Solving Word Problems with Arrays

Miss Mehan demonstrates how to create arrays from word problems, using counters to model scenarios. She solves three problems: arranging students in rows, placing stuffed animals on shelves, and distributing patches on a quilt. Each problem involves creating arrays and solving for totals or individual counts, emphasizing the simplicity of using arrays for problem-solving.
