Happy birthday Mr Dickens

2012-02-07T17:20:00.010+01:00

Today we are celebrating Charles Dickens' 200th birthday . I’m sure you know some things about this great English writer. He wrote about difficult lives in the “modern” city that London was in the Victorian times. He created characters which are still very well known – Ebeneezer Scrooge and Tiny Tim, Pip and Miss Havisham, Fagin and Oliver Twist. And he wrote such great books as “David Copperfield”, “Oliver Twist”, “Great Expectations” or “A Christmas Carol”.

Nowadays Dickens is more actual than ever. "You only have to look around our society and everything he wrote about in the 1840s is still relevant," said Dickens' biographer, Claire Tomalin. "The great gulf between the rich and poor, corrupt financiers, corrupt Members of Parliament ... You name it, he said it."

If you want to know something more about this writer click this link and you could find some interesting information about him.

SPORT ACROBATIC GYMNASTICS

2012-02-06T11:22:00.007+01:00

Hi there!

We have already started the second term. I hope you are enjoying the sport acrobatic gymnastics classes. Although I really think you are!

As I have told you in class, you will find the specific vocabulary you are going to need for these classes here.

Don´t forget you have to make the sport acrobatic gymnastics security rules poster by next Wednesday, February 8^th.

We´ll talk about your composition in groups for the practical exam next week. Meanwhile, maybe, you will find the following sport acrobatic gymnastics videos interesting.

The four of them are different, they use different types of music, themes, clothes, habilities, shapes, pyramids…

Remember that by next week you will have to be organized in groups of six, have selected your music and chosen a theme.

Please don´t let this go for the last minute. You will have a better outcome if you work on it with enough time.

A review of Decimals

2012-02-05T20:23:00.001+01:00

Hi my dear students,

this unit is called Decimal Numbers, those who have a decimal point.The decimal point is the most important part of a Decimal Number. It is exactly to the right of the Units position. Without it, we would be lost ... and not know what each position meant.

PLACE VALUES
Each place in a number has a different place value. Below is achart that shows the different place values in a number. As welook at this diagram, notice the spelling changes from the placesto the left of the decimal point (which represent places for wholenumbers) and the decimal places to the right of the decimal point.

Practice 1 and Practice 2. Game

ORDERING DECIMALS

Ordering decimals can be tricky. Because often we look at 0.42 and 0.402 and say that 0.402 must be bigger because there are more digits. But no!

If you follow the following method you will see which decimals are bigger.

Set up a table with the decimal point in the same place for each number.
Put in each number.
Fill in the empty squares with zeros.
Compare using the first column on the left, and pick out the highest in order.
If the digits are equal move to the next column to the right until one number wins.

Practice on this links: Comparing decimals and Ordering decimals.

ROUNDING DECIMALS
Rounding off a decimal is a technique usedto estimate or approximate values. Rounding is most commonly usedto limit the amount of decimal places. Instead of having a longstring of decimals places, or even one that goes on forever, wecan approximate the value of the decimal to a specified decimalplace.

When to Round Up

Rounding up means that we increase the terminating digit by a value of 1 and drop off the digits to the right. If the next place beyond where we are terminating the decimal is greater than or equal to five, we round up.

When to Round Down

If the number to the right of our terminating decimal place is four or less (4, 3, 2, 1, 0), we round down. This is done by leaving our last decimal place as it is given and discarding all digits to its right.

Practice on this link.Play a game.

OPERATIONS WITH DECIMALS

In this post we will give a review of some basic operations withdecimals. Performing these operations with decimals is like doingthem with whole numbers. The difference is the way that you needto keep track of the decimal point.

ADD
Practice 1, Practice 2, Practice 3, Practice 4

SUBTRACT

THE BAROQUE ERA

2012-02-03T20:55:00.003+01:00

The magnificent Basilica of San Marco in Venice attracted musical directors of the highest calibre in the 16th and 17th centuries, including Adrian Willaert, Gioseffo Zarlino and Claudio Monteverdi. The Byzantine dome allowed for various placements of multiple choirs and instrumentalists. This inspired composers such as Andrea Gabrieli and his nephew Giovanni Gabrieli to explore antiphonal elements and dynamic effects.

USE YOUR SEARCH ENGINE TO VIEW A PHOTO GALLERY OF THIS MUSICALLY SIGNIFICANT LANDMARK.

I'd really appreciate it if you sent me your comments on it.

One last thing. Remember: the better a Power Point is, the clearer the contents are. So, please, don´t copy-paste never-ending paragraphs, because nobody is going to read them. Your Power must be appealing, clear and original.

Good luck!

Negative numbers (I. Whole numbers, number line)

2011-12-12T21:25:00.002+01:00

Hello boys and girls,

now that the weather is getting colder, it is the best time of the year to study NEGATIVE NUMBERS :-)

These are part of a bigger group, called Whole Numbers.

To study them, the number line is very useful; it may help you to tell which numbers are bigger or smaller. Read about number line by clicking here (remember to solve the six questions down). After that, play this game for a while to see if you really understood...

At the end of the class, if you feel comfortable with number line and operations on it, try with this game, with more difficult movements... Play

Sieve of Eratosthenes

2011-11-06T19:49:00.007+01:00

The Sieve of Eratosthenes is an ancient method for finding all primes numbers up to a specified number.

It was created by Eratosthenes (275-194 B.C., Greece), an ancient Greek mathematician. Just as a sieve is a strainer for draining spaghetti, Eratosthenes's sieve drains out composite numbers and leaves prime numbers behind. The numbers from 1 to 100 are listed in a table. We will use The Sieve of Eratosthenes to find all primes up to the number 100 by following the directions below.

Directions:

Cross out 1 since it is not prime.
Circle 2 because it is the smallest prime number. Cross out every multiple of 2.
Circle the next open number, 3. Now cross out every multiple of 3.
Circle the next open number, 5. Now cross out every multiple of 5.
Circle the next open number, 7. Now cross out every multiple of 7.
Continue this process until all numbers in the table have been circled or crossed out.

You have just circled all the prime numbers from 1 to 100!
Download presentation

Questions (to be answered as a comment):

1. How many prime numbers are there from 1 to 100?
2. List all prime numbers from 1 to 100.
3. Which number is the only even prime number?
4. An emirp (prime spelled backwards) is a prime that gives you a different prime when its digits are reversed. For example, 13 and 31 are emirps. List all emirps between 1 and 100.

Enjoy it!

Square roots

2011-10-25T12:17:00.001+02:00

The opposite of squaring a number is called finding the square root.

See some examples here.

A square root of a number is a value that can be multiplied by itself to give the original number.

A square root of 9 is 3, because when 3 is multiplied by itself you get 9.

It is like asking:

What can I multiply by itself to get this?

To help you remember think of the root of a tree:

"I know the tree, but what is the root that produced it?"

In this case the tree is "9", and the root is "3"

Here are some more squares and square roots:


4		16
5		25
6		36

These are the first perfect squares:

It is easy to work out the square root of a perfect square, but it is really hard to work out other square roots.

Example: what is √10?

Well, 3 × 3 = 9 and 4 × 4 = 16, so we can guess the answer is between 3 and 4.

Let's try 3.5: 3.5 × 3.5 = 12.25
Let's try 3.2: 3.2 × 3.2 = 10.24
Let's try 3.1: 3.1 × 3.1 = 9.61
...

Getting closer to 10, but it will take a long time to get a good answer!

At this point, I get out my calculator and it says:

3.1622776601683793319988935444327

But the digits just go on and on, without any pattern.

So even the calculator's answer is only an approximation !

The Easiest Way to Calculate a Square Root

Use your calculator's square root button!

(And also use your common sense to make sure you have the right answer)

SECULAR VOCAL MUSIC OF THE MIDDLE AGES

2011-10-24T23:18:00.005+02:00

WEBQUEST
Among the earliest notated secular poems are Goliard songs -verses in Latin with subjects ranging from tender love lyrics to obscene drinking songs. A famous 13th-century manuscript known as Carmina burana (Songs of Beur) has been immortalized through its adaptation by 20th-century composer Carl Orff.

SEARCH ONLINE FOR PICTURES OF THIS MANUSCRIPT AND RECORDINGS OF SONGS FROM IT. You may recognize one of the songs, "O, Fortuna", from its use in numerous popular films and television commercials.

1. The exponent of a number says how many times to use the number in a multiplication (2 in the example)

2. The base, that says what number is multiplied by itself (8 in the example)

Try on the following website to multiply any number by itself as many times as you want using exponents: See website

If you want to learn what is the meaning of cubed, squared or index form go to the next link: Click here

Once you know everything about powers, you only have to go over the index laws.

To finish with powers, have a little practice by doing these exercises.

The earliest documentation of the existence of Léonin and Pérotin occurred in a treatise from ca 1275. The author is unknown to us but is referred to as "Anonymous IV". He praises the skills and accomplishments of the two master composers with reference to specific works and techniques. Today, the four-voice female ensemble aptly named Anonymous 4 specializes in Medieval music.

Listen to a recording by this group to enrich your experience with the music of this era.

Pythagoras Theorem

2011-10-06T12:35:00.007+02:00

Years ago, a man named Pythagoras found an amazing fact about triangles:

"if the triangle had a right angle (90º)... and you made a square on the three sides, then... the biggest square had the exact same area as the other two squares put together!

It is called Pythagoras Theorem, and can be written in a short equation: a² + b² = c^2

Note:

^{c is the longest side called Hypothenuse}
a and b are the other sides, named cathetus or legs

Then, the Theorem says: In a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Rounding and estimating

2011-10-02T18:52:00.013+02:00

Estimating is an important part of mathematics and a very handy tool for everyday life. It is not always necessary to give the exact number. Get in the habit of estimating amounts of money, lengths of time, distances, and many other physical quantities. For example, if there were 54 785 inhabitants in a town, you could say that its population was approximately 55 000. By doing this, what we have done is to round to the nearest thousand.

Rounding off is a kind of estimating.

To round off decimals:

Find the place value you want (the "rounding digit") and look at the digit just to the right of it.
If that digit is less than 5, do not change the rounding digit but drop all digits to the right of it.
If that digit is greater than or equal to five, add one to the rounding digit and drop all digits to the right of it.

To round off whole numbers:

Find the place value you want (the "rounding digit") and look to the digit just to the right of it.
If that digit is less than 5, do not change the "rounding digit" but change all digits to the right of the "rounding digit" to zero.
If that digit is greater than or equal to 5, add one to the rounding digit and change all digits to the right of the rounding digit to zero.

Depending on the study, we may need to round to the nearest ten, hundred, thousand, ten thousand...

I give you some links to practice here,

Round to the nearest thousand, ten thousand, hundred thousand.

Have fun

Statistics Review: Mean, mode, median, range, quartiles

2011-10-02T18:23:00.006+02:00

Statistics is the study of data: how to collect, summarize and present it. We commonly use some parameters to support our statistic studies, these are the following I sum up here for you:

The statistical mean is commonly called the average:

To find the mean of a group of numbers:
Add the numbers together
Divide by how many numbers were added together

Mean 1

Mean 2

The statistical mode is the number that occurs most frequently in a set of numbers.

To find the mode of a group of numbers:
Arrange the numbers in order by size.
Determine the number of instances of each numerical value.
The numerical value that has the most instances is the mode.
There may be more than one mode when two or more numbers have an equal number of instances and this is also the maximum instances
A mode does not exist if no number has more than one instance.
Example: The mode of 2, 4, 5, 5, 5, 7, 8, 8, 9, 12 is 5.

Mode

The statistical median is middle number of a group of numbers that have been arranged in order by size. If there is an even number of terms, the median is the mean of the two middle numbers:

To find the median of a group of numbers:

Arrange the numbers in order by size
If there is an odd number of terms, the median is the center term.
If there is an even number of terms, add the two middle terms and divide by 2.

Median 1

Median 2

The statistical range is the difference between the lowest and highest valued numbers in a set of numbers.

To find the range of a group of numbers:
Arrange the numbers in order by size
Subtract the smallest number from the largest number.

Range 1

Range 2

Quartiles are the values that divide a list of numbers into quarters.

First put the list of numbers in order
Then cut the list into four equal parts
The Quartiles are at the "cuts"
