The perimeter of a shape represents the distance around it, the area of a shape is the surface or flat space that the shape covers (in 2D) while the volume of a shape is the space it occupies in real life (in 3D).

**4th Grade** Math: Perimeter, Area & Volume - Chapter Summary

The self-checking quizzes and transcripts could also come in handy when they're ready to tackle more complex formulas for the surface area and volume of cones, cylinders, pyramids and other 3-D shapes.

**Logical reasoning tips and advice**

- Familiarity is key. Logical reasoning tests can look very complex at first glance.
- Have a system.
- Don't spend your first moments looking at the answers.
- Practice thinking logically.
- Practice makes perfect.

The base of this parallelogram is b1+b2 and the height is h. The area of the parallelogram is (b1+b2)h. Therefore, the area of the trapezoid is (b1+b2)h2.

Area of Trapezoid.

Shape | Area Formula | Picture |
---|---|---|

Triangle | A=bh2 | h b |

Trapezoid | A=(b1+b2)h2 | b 1 b 2 h |

Rhombus | A=bh or A=d1d22 | b h d 1 d 2 |

Kite | A=d1d22 | d 1 d 2 |

Biological sciences is the study of life and living organisms, their life cycles, adaptations and environment. There are many different areas of study under the umbrella of biological sciences including **biochemistry, microbiology and evolutionary biology**.

An **R.F.** **scale** is a ratio, or fraction, that expresses the mathematical relationship between MAP and LAND. Sometimes the actual dimensions of the object will be adopted on the drawing then in that case it is represented by the scale and RF as Scale: 1 cm = 1 cm or 1 : 1 and by RF = 1 / 1 (equal to one).

Business studies is an academic subject taught in schools and at university level in many countries. Its study combines elements of **accountancy, finance, marketing, organizational studies, human resource management, and operations**.

Knowing English **increases your chances of getting a good job in a multinational company within your home country or for finding work abroad**. It's also the language of international communication, the media and the internet, so learning English is important for socialising and entertainment as well as work!

Indirect speech is **speech which tells you what someone said, but does not use the person's actual words**: for example, 'They said you didn't like it', 'I asked her what her plans were', and ' Citizens complained about the smoke'.

**There are four main types of consumer behavior:**

- Complex buying behavior. This type of behavior is encountered when consumers are buying an expensive, infrequently bought product.
- Dissonance-reducing buying behavior.
- Habitual buying behavior.
- Variety seeking behavior.

**Time, size, distance, speed, direction, weight, volume, temperature, pressure, force, sound, light, energy**—these are among the physical properties for which humans have developed accurate measures, without which we could not live our normal daily lives.

**How to write an index**

- Start with your topic headings. Add one or more index entries for each topic heading.
- Consider other words that users might look for to find these topics.
- Look for keywords in each topic.
- Think of synonyms for the keywords.
- Brainstorm other words users might look for.
- Read the completed index.

Important classes of inorganic compounds are **the oxides, the carbonates, the sulfates, and the halides**. Many inorganic compounds are characterized by high melting points. Inorganic salts typically are poor conductors in the solid state.

Linear equations in three variables. If a, b, c and r are real numbers (and if a, b, and c are not all equal to 0) then **ax + by + cz = r** is called a linear equation in three variables. (The “three variables” are the x, the y, and the z.) The numbers a, b, and c are called the coefficients of the equation.

**Top 10 Biology Experiments**

- Dissect a Flower.
- Raise a Butterfly.
- Extract DNA.
- Make a Seed Board.
- Dissect an Owl Pellet.
- Look at Fingerprints.
- Grow an Herb Cutting.
- Make a Habitat Diorama.

**What the Teachers Recommend**

- Build confidence.
- Encourage questioning and make space for curiosity.
- Emphasize conceptual understanding over procedure.
- Provide authentic problems that increase students' drive to engage with math.
- Share positive attitudes about math.

**Cons of Virtual Meetings vs Face-to-Face Meetings**

- Interactions Between Participants Are Difficult.
- Visual and Audio Only.
- Less Dynamic.
- Internet Connections Can Fail.
- Team Members May Be in Different Time Zones.
- Participants May Not Know Each Other.
- Pay for Software.
