Introduction

(5 minutes)
Calculating Area in the KitchenPractice Finding Area #5: Pick the House
  • Ask students to look around their classroom and estimate how big it is. Listen to student responses. Probe how they would find out exactly how big the room is.
  • Tell students that when they are adults, they will look for an apartment or house to live in and that usually people like to find out the square footage of the place, or how big the space is.
  • Explain to students that today they will practice how to find the area of a rectangular room and emphasize that the area is the entire space inside the rectangle.

Beginning

  • Define the terms "estimate," "rectangular," "square footage," and any other tricky words in student-friendly terms in English (L2) and students' home languages (L1) as applicable.

Intermediate

  • Have students talk with a partner about their experience of thinking of area (of a shape or of a room) to stimulate their prior knowledge.
