Overview

In this interactive activity, students will be led through steps to calculate the area of a parallelogram. There are teaching activities as well as practice activities available.  A handout that reviews the steps taught during the interactive is available to be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.

Mathematics (2019) Grade(s): 3

MA19.3.20

Find the area of a rectangle with whole number side lengths by tiling without gaps or overlays and counting unit squares.

Unpacked Content

UP:MA19.3.20

Vocabulary

  • Area
  • Rectangle
  • Tiling
  • Gap
  • Overlay
  • Unit square

Knowledge

Students know:
  • area is a measurable attribute of two-dimensional figures.

Skills

Students are able to:
  • Find the area of a rectangle by tiling it without gaps or overlaps.
  • Measure the area of a rectangle by counting the number of unit squares needed to cover the shape.

Understanding

Students understand that:
  • Area is the number of unit squares needed to cover a surface.
  • Multiple unit squares can be combined to measure the area of rectangles so long as the unit squares completely cover the figure without overlapping each other or extending beyond the edge of the figure.
Mathematics (2019) Grade(s): 3

MA19.3.22

Relate area to the operations of multiplication using real-world problems, concrete materials, mathematical reasoning, and the distributive property.

Unpacked Content

UP:MA19.3.22

Vocabulary

  • Compose
  • Decompose
  • Area
  • Additive
  • Rectilinear figure
  • Equivalent
  • Non-overlapping
  • Overlapping

Knowledge

Students know:
  • Area is a measurable attribute of two-dimensional figures.
  • The area measurement of rectangular regions has a multiplicative relationship of the number of square units in a row and the number of rows.

Skills

Students are able to:
  • Decompose rectilinear figures as non-overlapping rectangles using concrete materials.
  • Find the area of two rectangles, and create a rectilinear figure by joining the two rectangles (without overlapping), and determine the area of the created rectilinear figure as the sum of the two rectangles.

Understanding

Students understand that:
  • rectilinear shapes can be decomposed into non overlapping rectangles, and the sum of the areas of the nonverlapping rectangles is equivalent to the area of the original rectilinear shape.
