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 sizes of different shapes. Students consider what it means for two-dimensional shapes to be larger or cover more space. They measure and describe relative areas with increasing precision as they participate in the activities in this lesson.

Give students access to pattern blocks and scissors during the Cool-down.

What part of the lesson went really well today in terms of students learning? What did you do that made that part go well?
