Students explore the concept of area as covering a surface, and to introduce the formula for calculating the area of a rectangle.

Teacher notes

  • Students estimate the area of the shape (square, rectangle or L shaped) using a reference square. Students cover the shape with the square, first completing a row or a column and then copying the entire row or column to complete the shape.
  • Students then calculate the area, using the dimensions of the shape to fill in the formula length X width.
  • An animated multiplication table supports students who experience difficulty with calculating the product.

Students work with L shaped shapes. Students calculate the area of each part of the L shape then add the results.
