Surface area and Volume of rectangular prisms

Posted by on Monday, May 28, 2012, In : Math Geometry and Measurement

Surface area of Rectangular Prism

For the surface area of a solid, there is a similar definition, but it applies to the exterior surfaces of the solid. Surface area is the sum of all unit squares that fit on the exterior of a solid.

As the diagram below indicates, there are six surfaces to a rectangular prism. There is a front, back, top, bottom, left, and right to every rectangular prism. The surface are of a prism is nothing more than the sum of all the areas of these rectangles.

Notice that...

Surface area and Volume of a cylinder

Posted by on Monday, May 28, 2012, In : Math Geometry and Measurement

Surface area of a cylinder

Definition: The number of square units it takes to exactly cover the surface of a cylinder.

Try this Drag the orange dot to the left to "unroll" the cylinder.

Volume enclosed by a cylinder

Definition: The number of cubic units that will exactly fill a cylinder

Try this Drag the orange dot to resize the cylinder. The volume is calculated as you drag.

Since the end (base) of a cylinder is a circle, the area of that circle is given by

Square Root

Posted by Patcharin Sinthunavarat on Saturday, March 24, 2012, In : Math

Squares and Square Roots

First learn about Squares, then Square Roots are easy.

How to Square A Number

To square a number, just multiply it by itself ...

Example: What is 3 squared?

3 Squared

= 3 × 3 = 9

"Squared" is often written as a little 2 like this:

square root of 9 is 3
This says "4 Squared equals 16"
(the little 2 says the number appears twice in multiplying)

Squares From 1² to 6²

...

1 Squared	=	1²	=	1 × 1	=	1
2 Squared	=	2²	=

Indefinite Pronouns

Posted by on Saturday, March 3, 2012, In : Language Arts

An indefinite pronoun does not refer to any specific person, thing or amount. It is
vague and "not definite". Some typical indefinite pronouns are:

all, another, any, anybody/anyone, anything, each, everybody/everyone,
everything, few, many, nobody, none, one, several, some, somebody/someone

Note that many indefinite pronouns also function as other parts of speech. Look at
"another" in the following sentences:

He has one job in the day and another at night. (pronoun)
I'd like anothe...

Rocks and soils

Introduction

Rocks can be hard, soft, permeable or impermeable, depending on what type of rock it is. Slate, marble, chalk and granite all have different uses.

Different plants grow better in different types of soil.

Characteristics of rocks

Some rocks are harder than others. For example, granite is a very hard rock, but chalk is a very soft rock and wears away easily.

Some rocks, such as sandstone or chalk, let water soak through them. They are called permeable r...

Solids and liquids

Introduction

Heat melts a solid and turns it into a liquid. Cooling freezes a liquid into a solid.

Different solids melt at different temperatures, some high some low. These are called their melting points.

Heating and cooling

Heating

Heat can change solids into liquids or gases.

Most solids melt into liquid when they are heated.
A liquid evaporates into a gas when it is heated.

Cooling

When we cool something we take heat away from it. Cooling changes a...

Reversible and irreversible changes

Introduction

Irreversible changes, like burning, cannot be undone. Reversible changes, like melting and dissolving, can be changed back again.

Mixtures can be separated out by methods like filtering and evaporating.

Irreversible changes

A change is called irreversible if it cannot be changed back again. For example you cannot change a cake back into its ingredients again.

Irreversible changes are permanent. They cannot be undone.

Gases, liquids and solids

Introduction

Solids, liquids and gases have different properties.

Liquids and gases can flow. Solids keep their shape. Gases can be squashed

Gases

Gases are often invisible.
Gases do not keep their shape or always take up the same amount of space. They spread out and change their shape and volume to fill up whatever container they are in.
Gases can be squashed.
Heating a liquid can turn it into a gas.
Cooling a gas can turn it into a liquid....

Changing state

Introduction

Solid, liquid and gas are called the three states of matter. Materials can be changed from one state to another by heating or cooling.

Water moves around the environment in the water cycle.

States of matter

Solid, liquid and gas are called the three states of matter.

Materials can be changed from one state to another by heating or cooling.

Numeracy Target for Year 5

Posted by iampatpatt on Saturday, March 20, 2010, In : Learning Information

By the end of Year 5, most children should be able to…

o	Multiply and divide any whole number up to 10 000 by 10 or 100.
o	Know what the digits in a decimal number stand for, e.g. the 6 in 2.63 stands for 6 tenths and the 3 for 3 hundredths.
o	Round numbers with 1 decimal place to the nearest whole number, e.g. 9.7 rounds up to 10, 147.2 rounds down to 147.
o	Use division to find a fraction of a number, e.g. find one fifth by dividing by 5.
o	Work...
