## Counting Numbers

Counting numbers are the set of numbers that we use to learn how to count. They are also called natural numbers, since they feel natural to us because they are naturally the first numbers to learn. Sometimes they are also referred to as positive integers. Counting: Number Names to 100 1 2 3 4 5 … Continue reading "Counting Numbers"

## Reflex Angle

A Reflex Angle is more than 180° but less than 360° More Examples of Reflex Angle Which Angle? Remember to look carefully at which angle you are being asked to name. The reflex angle is the larger angle. It is more than 180° but less than 360° If you choose the smaller angle you might … Continue reading "Reflex Angle"

## Concentric Circles

In geometry, 2 or more objects are said to be concentric, coaxial, or coaxal when they share the same axis or center. Circles, regular polygons, regular polyhedra, spheres, and cylinders may be concentric to one another (sharing the same center point). Definition of Concentric Circles Concentric Circles are 2 or more circles which have same center point. They fit inside each … Continue reading "Concentric Circles"

## Sets Theory

A set is a collection of distinct objects, considered as an object in its own right. For example, the numbers 1, 3, and 5 are distinct objects when considered separately, but when they are considered collectively they form a single set of size three, written {1, 3, 5}. The concept of a set is one … Continue reading "Sets Theory"

## Fractions

Definition Fraction is a number written with a numerator and a denominator, in which both are natural numbers. Numerator: the top number of fraction Denominator: the top bottom of fraction So, fraction is written as Numerator / Denominator Examples Fraction Numerator Denominator 1 2 2 3 3 4 7 40 99 123 Learn More Simplest … Continue reading "Fractions"

## Simplest Form of Fractions

Simplest form of A fraction is a fraction that has the top and bottom cannot be any smaller (simplified), while still being whole numbers. How to simplify a fraction? Divide the top and bottom by the greatest number that will divide both numbers exactly (Greatest Common Factor), they must stay whole numbers. Examples Fraction Greatest … Continue reading "Simplest Form of Fractions"

## Metric Mass (Weight)

Mass: how much matter is in an object. We measure mass by weighing, but Weight and Mass are not really the same thing. The most common measurements: Grams Kilograms Tonnes Grams Grams are written as g (for short), so 250 g = 250 grams Kilograms 1 kilogram = 1,000 grams Kilograms are written as kg … Continue reading "Metric Mass (Weight)"

## Geometry

Geometry is a branch of mathematics concerned with questions of shape, size, relative position of figures, & the properties of space. A mathematician who works in the field of geometry is called a geometer. There are some general concepts that are more or less fundamental to geometry. These include the concepts of points, lines, planes, … Continue reading "Geometry"
