Mathematics

3. A mathematical operation that finds the difference between two numbers. It's like taking away or removing some amount from a number.
5. A mathematical operation that splits or shares a number into equal parts. Imagine sharing a pizza equally among your friends!
7. A perfectly round shape that has a constant distance from its center to any point on its boundary. It's a closed curve with no straight sides or corners.
8. The process of determining the size, length, or quantity of something using standard units. It helps us understand and compare the attributes of objects or quantities. Imagine doing it using rulers, scales, or other tools!
10. A mathematical operation that combines two or more numbers to find the total or sum. It's like putting numbers together to see how much you have in total.
12. A quadrilateral with four equal sides and four right angles. All sides of it are the same length, and its corners form 90-degree angles.
13. A two-dimensional or three-dimensional figure with specific characteristics and boundaries. It can have different sizes, angles, and properties.

1. A way of representing a part of a whole or a part of a group. They have a numerator (the top number) that represents the part and a denominator (the bottom number) that represents the whole. Imagine dividing a pizza into equal slices and describing how much you have!
2. A mathematical operation that combines equal groups or repeated additions. It's like adding the same number multiple times.
4. The space between two intersecting lines or surfaces measured in degrees. They can be acute (less than 90 degrees), right (exactly 90 degrees), obtuse (more than 90 degrees but less than 180 degrees), or straight (exactly 180 degrees).
6. A number expressed including a point. They are used to represent parts of a whole or to show more precise values than whole numbers. Imagine using it to describe measurements or money!
9. A symbol or a word that represents a quantity or value. For example, things like 1, 2, 3. It can be used to count, measure, or perform calculations. They can be fractions, or decimals.
11. A polygon with three sides and three angles. It can have different types, such as equilateral, isosceles, or scalene, based on the length of their sides and angles. Imagine a shape you can draw with three lines!
