Students will be able to create a verbal and or written set of instructions, or algorithm, for building a house out of plastic bricks.

Introduction

(5 minutes)

Review the story of The Three Little Pigs with students and ask students to recall the house the third little pig built. Ask students, “How did the third little pig build such a strong house?” Students may mention the materials, the bricks, that were used to make it strong.
Ask students questions that focus on the building process. “How did the little pig build that house out of bricks? What did he have to do first? What did he do next?” Students may be able to explain that he probably built the walls first and then the roof. They may also mention details such as adding doors and windows.
Then ask, “How do you think the little pig learned to build the house? Do you think he already knew how to build a house?” Ask questions that help students make connections to their own experiences making things. Guide students to recognize that knowing how to build something sometimes requires instructions.
