Lesson 1
¿Qué es el área?
Lesson Purpose
The purpose of this lesson is for students to recognize that different shapes cover different amounts of space.
Lesson Narrative
In grade 2, students estimated, measured, and compared lengths using standard units. They learned how the length of the unit affects measurements.
This lesson introduces the concept of area as students compare the size of different shapes. Students consider what it means for two-dimensional shapes to be larger or cover more space. They measure and describe relative area with increasing precision as they participate in the activities in this lesson.
Give students access to pattern blocks and scissors during the cool-down.
