Blog 7 Intro to Area
As part of this week's lesson, I taught my students about the area of rectangles and squares, which they found quite interesting. Students should be aware that the area of a square or a rectangle is measured in equal-sized squares and rectangles. They should also be able to determine how much space is contained within rectangles and squares in a timely manner.
To begin the lesson, I explained to the class that the amount of space occupied by a flat shape or surface is measured in square feet. The surface area of a closed figure is equal to the number of unit squares that cover the surface of the figure when it is closed. Square units are used to measure area, such as square millimeters, square feet, and square inches, among other things. After that, we watched a film that introduced us to area. After that, I projected a board on the smartboard and asked the students how much area the board took up on the screen. After that, I explained that one method of determining the area of the grid was to count all of the squares contained inside it.
