This is a great collection of worksheets to get started on the concept of area. Area is abstract concept for students because it is hard to understand in words. When we say that area is just a measure of the size of the surface of an object, students get confused. If you have students use a piece of graph paper and ask them to outline any four boxes on that page, keeping in mind that you are trying to find the largest boxes. After a while they will tell you that all the boxes are the same, so there is no way to have the largest boxes and they would be right. It does not matter how you arrange area it is the same amount of surface. The exact calculating that you use to find the area of a shape differs depending on what shape you are referring to. We often start with rectangles and work up from there. When calculating area we also must make sure that our units of measurement are properly displayed as well.
The concept of squared units is presented along with this topic. Make sure that students really grasp that concept because it is used often in higher level geometry. In the first batch the measures of the shapes (rectangles) is specifically stated. We introduce this by offering students the concept of area units. The second batch of requires students to determine those measures on their own by using the coordinate grid outlines that serve as the background image of the sheets. We learn the formulas for calculating the area of different shapes, and how to properly convert and notate square units such as feet, inches, centimeters, etc.
