Block perimeter applet
This applet is designed to help students understand the meaning of perimeter for regular and irregular shapes. Square boxes can be dragged to the applet's screen to form a shape. The area is determined by the number of boxes in the shape. The perimeter is found by counting the number of unattached sides. Students can check their answer by clicking the Show Perimeter button. Directions explaining how to link the boxes are included. Copyright 2005 Eisenhower National Clearinghouse

3.2 Necessities and luxuries

As the division of opinion between the government and low income people illustrates, definitions of poverty are the stuff of political debate. People in the Rowntree studies tended to focus on ‘paying bills and food’. Most people's list of basic needs would also include adequate food and clean water, clothing, shelter and heating. But are there also less apparently physiological, more evidently social, necessities of life?

Professor Peter Lambert inaugural lecture: The Priest, the Coup and the Party
In 2008 Fernando Lugo came to power in Paraguay promising a 'new dawn' based on social justice, democracy and greater empowerment of the country's poor but just four years later, with his reform programme in tatters. In his inaugural lecture, Professor Peter Lambert examines the failure of Lugo's reform programme through analysis of both immediate causes and wider factors related to domestic power relations and political culture. This in turn raises questions about the very nature of Paraguay'

17.905 Forms of Political Participation: Old and New (MIT)
How and why do we participate in public life? How do we get drawn into community and political affairs? In this course we examine the associations and networks that connect us to one another and structure our social and political interactions. Readings are drawn from a growing body of research suggesting that the social networks, community norms, and associational activities represented by the concepts of civil society and social capital can have important effects on the functioning of democracy

4.2 Fractions

Instead of putting the two left over biscuits back in the tin, you might instead decide to break them into halves and then give one of the resulting four halves to each person so that everyone receives a total of one and a half biscuits. In this case, the answer has to be expressed as a fraction or the equivalent decimal number:

  • 6 ÷ 4 = 1½
  • 6 ÷ 4 = 1.5

A fraction is really just another way of expressing a division because ½ means

6 Permeability

It is important to distinguish clearly between porosity and permeability. Porosity is a measure of how much water can be stored in a rock, whereas permeability is a measure of the properties of a rock which determine how easily water and other fluids can flow through it (see Section 4). Permeability depends on the exte

4.2 Instantaneous acceleration

The procedure of Question 15 for determining the instantaneous velocity of the car can be carried out for a whole set of different times and the resulting values of vx can be plotted against t to form a graph. This has been done in Figure 28, which shows how the velocity varies with time. At time t = 0 s, the car has zero velocity because it starts from rest. At later times, the velocity is positive because the car moves in the direction of incre

3.1 Areas of quadrilaterals and triangles

You may like to add the area formulas in this section to your notes for future reference.

The simplest areas to find are those of rectangles. The area of a rectangle is its length multiplied by its breadth. Sometimes the dimensions of a rectangle are referred to as the base and the height, instead of the length and the breadth. The area is then expressed as the base multiplied by the height.

2.2 A society frightened by crime?

We do not have to look too far to find someone saying that the UK is a society gripped by rising levels of crime, anti-social behaviour and incivility; or that disorder threatens social stability. The criminologist Robert Reiner suggests that ‘in the last 40 years, we have got used to thinking of crime, like the weather and pop music, as something that is always getting worse’ (Reiner, 1996, p. 3). So who is telling this story?

Most of us will have heard older family members and fri

2.3 Wales

In 1282, Edward I conquered Wales and the Statute of Rhuddlan (or Statute of Wales, 1284) established English rule. Rather than involve the assimilation of the Welsh by the English the conquest saw ‘a colonial system … established in those parts of Llywelyn's Principality which were by 1284 in the hands of the king’ (Davies, 1991, p. 166). In 1400, Owain Glyndwr led the most outstanding and successful rising in Wales against the new order and the tyranny of the English border barons, wh

What you get is what you expect
Pain is a major health care problem worldwide. It affects the well-being of millions of individuals, and its financial burden upon our societies is considerable. Pain is not a simple reflection of the degree of tissue-damage, it is strongly influenced by expectations and beliefs individuals hold about pain and their ability to cope with it. In this lecture, Dr Katja Wiech from the Centre for Pain Research, talks about research into how expectations can influence the outcome of pain treatment.

1.2 Napoleon and the Spanish imbroglio

Napoleon later admitted that his intervention in Spain in 1807 was among his worst mistakes. He referred to it as ‘the Spanish wasps’ nest’ or ‘the Spanish ulcer’, which divided and exhausted his military strength. While Napoleon probably intended to annex the Iberian peninsula to his French empire in any event, his immediate involvement arose from his decision in November 1806 to impose the Continental Blockade or European boycott of British goods, in the hope of defeating Britain
