WELCOME GRADE-3 STUDENTS TO MATH ONLINE CLASS.
The Cambridge Primary Mathematics(0845) curriculum is presented in five content areas: Number, Geometry, Measure, Handling data and Problem solving. The first four content areas are all underpinned by Problem solving, which describes using techniques and skills and the application of understanding and strategies in solving problems. Mental strategies are also a key part of the Number content. This curriculum focuses on principles, patterns, systems, functions and relationships so that learners can apply their mathematical knowledge and develop a holistic understanding of the subject. The Cambridge Primary Mathematics curriculum framework provides a solid foundation upon which the later stages of education can be built.
Class rules :
Dear Students,
Greetings from the Royal British International School!
My name is Ms. Sameena and I will be your Mathematics Teacher.
Here are my contact details:
Email: [email protected]
Mobile:+959979223225 (What’s App only)
Rules:
WhatsApp groups are created in order to keep the avenues open with regards to communication. Effective communication is essential and WhatsApp has proven to be an ideal medium.
With these groups, however, comes the responsible use of its members.
Please take note of the following:
* NO messages are permitted to be posted before 8:00 a.m. and after 8:00 p.m., seven days a week.
* NO general conversations. Please, rather chat to the person concerned via a private message instead of subjecting the group to long-winded chats on the group. It can become distracting and annoying to group member.
* NO harsh words, gossiping, unpleasant comments, online bullying or nastiness. These sort of issues should be brought directly to the homeroom teacher’s attention or the Schools Principal.
* Unless absolutely necessary, they are NOT a platform to help find lost property.
* They are NOT a platform to ask about what homework needs to be done. You are accountable for your own homework and your responsibility to submit it on time.
* This group is not a platform to air grievances or complaints; It would be preferred that members message the concerned person privately or speak to your homeroom teacher and /or School Principal.
* They are NOT a platform to post pictures that you feel your classmates may find funny or cute.
“Please remember, WhatsApp Groups are meant to be useful and certainly not something that proves to be irritating to members. Think before you type!”
Our first lesson will officially start on Tuesday. Looking forward to a fruitful and productive Academic year.
Stay Safe!

AREA AND PERIMETER
The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers. You measure area in square units of a fixed size. for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. |

What are 2 and 3 dimensional shapes?
A two-dimensional (2D) shape has only two measurements, such as length and height. A square, triangle, and circle are all examples of a 2D shape. However, a three-dimensional (3D) shape has three measurements, such as length, width, and height. |
|
|
Length, width, and height are measurements that allow us to indicate the volume of geometric bodies.
length pertains to the longest side of the rectangle while width is the shorter side. 3. Length can also refer to an extent of time or a measure of distance How To volume? Length x Width x Height. (LxWxH) where the height is the vertical dimension of the box when the opening is facing upwards. |

7(B) WEIGHT
weight and mass are measured using scales. • they are often measured with the same units. e.g. kilograms or pounds.
The Metric System of Measurements uses the mass units: gram (g), kilogram (kg) and tonne (t).
The kilogram (kg) is the largest unit of weight and equals 1000 grams.
The kilogram (kg) is the largest unit of weight and equals 1000 grams.

7(C) CAPACITY
The amount that something can hold. Usually it means volume, such as milliliters (ml) or liters (l) in Metric, or pints or gallons in Imperial. Example: This glass has a capacity of 300 ml (but is actually holding only 160 ml).
Capacity is the ability to hold something, very similar to volume. Capacity is measured in the SI base unit called litres (L). The most common units for capacity are litre (L) and millilitre (mL). The milliliter (ml) is the smallest metric measure of volume and equals 1/1000 of a liter. The centiliter (cl) is the next largest unit of volume and equals 1/100 of a liter. The deciliter (dl) is the next largest unit of volume and equals 1/10 of a liter. |

UNIT - 8 MULTIPLICATION, DIVISIONS AND PATTERNS
8(B) DIVISIONS
What are parts of division?
Each part of a division equation has a name. The three main names are the dividend, the divisor, and the quotient. What is division and examples? Division is splitting into equal parts or groups. It is the result of "fair sharing". Example: there are 12 chocolates, and 3 friends want to share them, how do they divide the chocolates? Answer: They should get 4 each. |

8(C) NUMBER PATTERNS AND SEQUENCES
What is number patterns and sequences?
A Sequence is a set of things (usually numbers) that are in order. Each number in the sequence is called a term.
Number sequences are sets of numbers that follow a pattern or a rule. If the rule is to add or subtract a number each time, it is called an arithmetic sequence. If the rule is to multiply or divide by a number each time, it is called a geometric sequence.

UNIT - 9 GEOMETRY
geometry is the mathematical study of shapes and space. Geometry can deal with flat, two-dimensional shapes, such as squares and circles, or three-dimensional shapes with depth, such as cubes and spheres.
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.
What are the three properties of a triangle?
Properties of a Triangle:-
A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side.

What is perimeter and area examples?
Perimeter for a 2-dimensional shape is the total distance around the respective shape. For the figures with straight sides such as triangle, rectangle, square or a polygon; the perimeter is the sum of lengths for all the sides. The peripheral border in blue is the perimeter of the park.
How is area and perimeter related?
the area is proportional to the square of the perimeter, where the constant of proportionality depends on the shape you chose. For example, a square of perimeter has area , while a circle of perimeter has area .

Decimals
What is a decimal number?
In algebra, a decimal number can be defined as a number whose whole number part and the fractional part is separated by a decimal point. The dot in a decimal number is called a decimal point. The digits following the decimal point show a value smaller than one. Here's an example of a decimal number 13.95, in which 13 is the whole number, while 95 is the decimal part. |
13(B) Measurements ( Length, weight and capacity)
Measurement of mass is most commonly done by a Balance. The unknown mass of a body is compared with a known value of mass. We obtain the value of an unknown mass in terms of a known value of mass
