Big Ideas: Area of flat shapes can be measured with "unit squares" as touching, non-overlapping squares. This lessons builds on students' work with tiling non-rectangular shapes using improvised units. This task uses a scenario in which students will tile rectilinear flat shapes to determine how many unit squares make up the surface area of each shape. Students will be presented with various shapes to tile and sort from smallest area to greatest area. Students will be building their foundational knowledge of area by tiling and counting unit squares inside of shapes. The mathematical concepts in this lesson build toward students' future work with measuring area of rectilinear shapes. Vocabulary: plane figure, surface area, flat space, unit square, one square unit Special Materials: Student Handout (optional)
