Description

"Graphics and Measurement" PPT

Part 1: Create a scenario and start review

1. Knowledge of length, area and volume.

①The park is being renovated and greened, and the worker uncle is preparing to do some data measurements. Let’s also participate in them, okay?

②Think about it, what data do you need to know about graphic measurement? What units will be used?

length, area, volume

③What is length? What is area? What is volume?

Length: The distance between two points. Area: The size of the plane.

Volume: The amount of space an object occupies.

2. Measurement unit and progress rate.

In addition to data, measurement also requires units and rates.

(1) Commonly used units of length, area and volume.

Commonly used units of length: kilometers, meters, decimeters, centimeters

Commonly used area units: square kilometers, square meters, square decimeters, square centimeters

Commonly used units of volume: cubic meter, cubic decimeter (liter), cubic centimeter (ml)

(2) Unit conversion method.

When a large thing is transformed into a small one, it is multiplied by the rate of progress; when a small thing is brought together into a large one, it is divided by the rate of progress.

(3) Practice in time

0.5 meters = ( ) centimeters 8 square meters = ( ) square decimeters

500 cubic centimeters = ( ) cubic decimeters

3. Unit size

Use physical examples to describe the size of each unit.

4. The perimeter of a plane figure.

(1) What is the perimeter of a figure?

The sum of all the line segments surrounding the figure is called the perimeter of the figure.

(2) Unit conversion

①The rate of progress between adjacent length units, area units, and volume units.

②How to calculate the circumference of a rectangle, square, or circle?

Perimeter of rectangle = (length + width) × 2

Perimeter of a square = side length × 4

Circumference of a circle = pi x diameter = pi x radius x 2
