Imperial and metric measurements

Posted by ricardogm on 12th March 2012

Hi

Here you are some information about imperial measurements.

Frankie is going to tell you some facts about the units they use in Britain. Then you can do the following exercises: Send the questions to me in a word document, you can use copy and paste, this time 2. Then, do this quiz.

3. And, at last, play this game. Posted in General | No Comments »

Negative numbers

Posted by ricardogm on 8th December 2011 Hi

First of all, do the exercises in parts 2 and 3 of the unit

Open your book, page 81, and do exercises 5, 8 and 10

Two applets with geogebra: adding and subtracting integers.

The same thing, in spanish, with activities (Gauss proyect)

And some more easy exercises:

 3 + (-8) = (-9) - (-4) = 7 - 5 = 6 - (-4) = (-4) - (-2) = (-4) - 10 = 6 - 5 = (-2) - 5 = 4 + 1 = 4 + 2 = (-4) - (-10) = 9 - (-7) = 8 - 5 = 9 - (-9) = (-8) + (-2) = (-9) + 10 = (-5) + (-10) = 8 + (-10) = 8 + 6 = 2 - (-10) = (-4) - 4 = (-2) + 6 = 1 - (-7) = (-2) - 7 = 7 - 5 = 8 - (-2) = (-1) - 0 = (-1) - (-2) = (-2) + 5 = (-6) + 2 = 7 - 4 = 8 - (-2) = (-5) - (-6) =

Functions 1

Posted by ricardogm on 28th April 2011

Hi

Today we are going to learn to use Geogebra to work with functions and tables of function values. Please pay attention to the teacher.

Theory: (from www.teacherschoice.com.au)

A function is a set of ordered pairs where for any ‘x’ value in the set, there is only one ‘y’ value.

For example, this set of ordered pairs is a function: { (0,0) (1,1) (2,8) (3,27) }

A rule that generates the entire set is written as: ‘y = f(x)’, which is short for: ‘y is a function of x’.

The rule: y = x³ generates the set of ordered pairs above, plus an infinite number of other ordered pairs. It is a function because for every ‘x’ value, there is only one possible ‘y’ value: These results can be displayed in a table, like this:

 x y = f(x) 0 0³ = 0 1 1³ = 1 2 2³ = 8 3 3³ = 27

For more complicated functions, such as: y = 2x² - 5x + 2, a table of values will help you to evaluate and graph the function.
