establish the formula for the area of a rectangle and use it to solve practical problems

Elaborations

• 1 using one centimetre grid paper to construct a variety of rectangles, recording the side lengths and the related areas of the rectangles in a table to establish the formula for the area of a rectangle by recognising the relationship between the length of the sides and its calculated area
• 2 using the relationship between the length and area of square units and the array structure to derive a formula for calculating the area of a rectangle from the lengths of its sides
• 3 solving problems involving the comparison of lengths and areas using appropriate units
• 4 investigating the connection between the perimeters of different rectangles with the same area and between the areas of rectangles with the same perimeter
