Students find the areas of various shapes by covering them with square-inch tiles. This activity provides many opportunities to observe students’ work.

Content in this Lesson

  • Recognizing that different shapes can have the same area [E4].
  • Comparing and finding the area of shapes by counting square units using efficient counting strategies [E1, E6].
  • Using labels to explain what numbers mean [MPE6].
