Бүтін сандар – бөлшек бөлігі жоқ сандар. Оларға …, -3, -2, -1, 0, 1, 2, 3, … жатады.

Бөлшек сандар – бүтін емес, яғни бөліктен тұратын сандар. Мысалы: 1/2, 3/4, 0.5, 2.75.

Оң сандар – нөлден үлкен сандар. Мысалы: 1, 5, 10, 3.2.

Теріс сандар – нөлден кіші сандар. Мысалы: -1, -7, -0.5.

0 (нөл) – оң да, теріс те сан емес, ол бөлек қарастырылады.

Debate Topics on Fractions

1. Fractions are more useful than decimals in everyday life.

2. Understanding fractions is essential for success in mathematics.

3. Fractions should be taught before decimals in school.

4. Visual models make learning fractions easier.

5. Fractions are harder to understand than whole numbers.

Mathematics Glossary for KS3 Students

• Algebra: A branch of mathematics where letters are used to represent numbers in equations.

• Angle: The space between two lines that meet at a point, measured in degrees.

• Area: The amount of space inside a flat shape, measured in square units.

• Circle: A round shape where all points are the same distance from the centre.

• Equation: A mathematical statement that shows two expressions are equal, using an equals sign.

• Fraction: A way to represent a part of a whole, written with a numerator and a denominator.

• Geometry: The study of shapes, sizes, and properties of space.

• Perimeter: The total distance around the edge of a shape.

• Probability: The chance or likelihood that a particular event will happen.

• Volume: The amount of space that a 3D object takes up, measured in cubic units.

Understanding Different Types of Numbers

In this lesson, we explored various types of numbers in mathematics, focusing on whole numbers, fractions, positive and negative numbers.

Types of Numbers

• Whole Numbers: Numbers without any fractional part, such as …, -3, -2, -1, 0, 1, 2, 3, …

• Fractions: Numbers that represent a part of a whole, like 1/2, 3/4, 0.5, 2.75.

• Positive Numbers: Numbers greater than zero, e.g., 1, 5, 10, 3.2.

• Negative Numbers: Numbers less than zero, e.g., -1, -7, -0.5.

• Zero: Neither positive nor negative, considered separately.

Converting Mixed Numbers to Improper Fractions

We practised finding improper fractions from mixed numbers. For example:

• 3 1/2 is converted to 7/2.

• 4 3/4 is converted to 19/4.

Interactive Activities

• Drag and Drop: Classify numbers as positive or negative.

• Order numbers in ascending sequence.
