Correct Answer - Option 2 : Graph paper
Area is the term used to define the amount of space taken up by a 2D shape or surface. We measure area in square units cm² or m².
- Children are introduced to the area in class 5, where they will be asked to find the area of various shapes, simply by counting the 1cm² squares they occupy on paper.
- In class 6 children will be expected to use the formula (length x width) to work out the area of a rectangle. They will often be given rectangles not drawn to scale, so will need to remember this formula.
- They also need to estimate the area of irregular shapes. In class 7, children will need to work out how to find the area of an irregular shape, such as the following. Often, not all the measurements of each side will be given to make this harder.
- A good way of finding the area of a shape like this is to split the shape up into smaller shapes and then work out the area of each of these.
- The areas of the smaller shapes can then be added up to find the answer.
- Example: the best resource to compare the areas of two leaves in class 5. Bring in a nice variety of leaves for different species which have variable leaf shapes and sizes.
- It has been used to demonstrate the use of graph paper in measuring surface.
- Each of the examples were hand-drawn onto the grid paper using the same dried, pressed leaf as students would do in class.
Hence, it can be concluded that the best resource to compare the areas of two leave is graph paper.
