LOGICAL THINKING - Grade 2

Lesson 1 of 8

Activity 1

Motivate the students by letting them know that they are going to help be a detective today.

Read this story to the students to explain how to play a logic game:

Randy Raccoon loved being a scientist. He always carried a notebook to write down observations, test ideas, and ask questions. One sunny afternoon, Randy was busy studying leaves when his good friend, Detective Daisy Duck, waddled up.

“Hello, Randy!” Daisy quacked cheerfully. “I just finished solving a very tricky problem, and I thought you might like to hear how I did it.”

Randy’s eyes sparkled with curiosity. “Of course! I love learning how you use logic, Detective Daisy. You always figure things out in such a clever way.”

Daisy nodded. “Well, solving problems is a lot like being a scientist. You gather clues, stay organized, and test your ideas. Let me show you one of my favorite tools—a logic grid.”

Randy tilted his head. “What’s a logic grid?”

Daisy fluffed her feathers and explained, “A logic grid is a chart that helps you keep track of clues. It has rows that go across, and columns that go up and down. Each box where a row and column meet is a place to mark what you learn. I use X’s to mean ‘no’ and O’s to mean ‘yes.’ That way, I don’t forget what the clues tell me.”

Randy’s notebook was open in seconds. “Show me how it works!”

Daisy smiled. “All right. Let’s pretend Reiko, Carlos, and Ida each bought an ice cream cone. The flavors they bought were mint chocolate chip, vanilla, and strawberry. Our job is to figure out who bought which flavor.”

Daisy drew a big box on the ground with her stick. “Look, Randy. I’ll write Reiko, Carlos, and Ida along the side—that’s the rows. Then across the top, I’ll write mint chocolate chip, vanilla, and strawberry—those are the columns.”
