Measuring Space
Measuring Two-Dimensional Space•To measure two-dimensional space, you must use the concept of area, which represents the amount of flat surface a shape occupies and is measured in square units like square inches or square meters, essentially you multiply the length and width of a shape to calculate its area, as it only considers two dimension within a plane
Key Points About Measuring 2D Space
•Units always expressed in square units because you are multiplying two linear measurements (length and width)•Calculations is to find the area of a shape and use the appropriate formula based on its geometry (rectangle: length x width, triangle: 0.5xbasexheight).•Distinction from perimeter is the total length of all sides of a shape, area measures the space enclosed within those sides.
One, Two, and Three-Dimensional•In one dimension you are measuring distance (length)•In two dimensions you are measuring are ( length and width)•In three dimensions you are measuring volume (length, width, and height)
Formulas for Common ShapesSquare:Perimeter: P=4sArea: A=s^2Rectangle:Perimeter: P=2(l+w)Area: A=lwCirclePerimeter(Circumference): C=2TTrArea: A=TTr^2Triangle Perimeter: P=a a+b+c (where a, b, and c are side lengths)Area: A= (1/2) bh where be is the base and h is the height
Geometry Development in Young Children•Children ages 3-5 are beginning to learn about shapes, spaces, and locations-basic concepts of geometry. They use geometric thinking when they build with blocks assemble a floor puzzle or play a target game.
Use the Language of Geometry•Describe objects by their shape when you talk to children•Use words such as side, solid, surface, point, straight, curve, inside, flat, top, angle.•Look at different pictures and talk about how the artist uses their lines, and shapes.
