Time is a dimension in which events can be ordered from the past through the present into the future,[1][2][3][4][5][6] and also the measure of durations of events and the intervals between them.[3][7][8] Time has long been a major subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars.[3][7][8][9][10][11] Nevertheless, diverse fields such as business, industry, sports, the sciences, music, dance, and the live theater all incorporate some notion of time into their respective measuring systems.[12][13][14] Some simple, relatively uncontroversial definitions of time include "time is what clocks measure"[7][15] and "time is what keeps everything from happening at once".[16][17][18][19]
Two contrasting viewpoints on time divide many prominent
philosophers. One view is that time is part of the fundamental structure
of the universe—a dimension independent of events, in which events occur in sequence. Sir Isaac Newton subscribed to this realist view, and hence it is sometimes referred to as Newtonian time.[20][21] The opposing view is that time
does not refer to any kind of "container" that events and objects "move
through", nor to any entity that "flows", but that it is instead part
of a fundamental intellectual structure (together with space and number) within which humans sequence and compare events. This second view, in the tradition of Gottfried Leibniz[15] and Immanuel Kant,[22][23] holds that time is neither an event nor a thing, and thus is not itself measurable nor can it be travelled.
Time is one of the seven fundamental physical quantities in the International System of Units. Time is used to define other quantities — such as velocity — so defining time in terms of such quantities would result in circularity of definition.[24] An operational definition
of time, wherein one says that observing a certain number of
repetitions of one or another standard cyclical event (such as the
passage of a free-swinging pendulum) constitutes one standard unit such
as the second,
is highly useful in the conduct of both advanced experiments and
everyday affairs of life. The operational definition leaves aside the
question whether there is something called time, apart from the counting
activity just mentioned, that flows and that can be measured.
Investigations of a single continuum called spacetime bring questions about space into questions about time, questions that have their roots in the works of early students of natural philosophy.
Furthermore, it may be that there is a subjective component to time,
but whether or not time itself is "felt", as a sensation or an
experience, has never been settled.[3][7][8][25][26]
Temporal measurement has occupied scientists and technologists, and was a prime motivation in navigation and astronomy.
Periodic events and periodic motion have long served as standards for
units of time. Examples include the apparent motion of the sun across
the sky, the phases of the moon, the swing of a pendulum, and the beat
of a heart. Currently, the international unit of time, the second, is defined in terms of radiation emitted by caesium atoms (see below). Time is also of significant social importance, having economic value ("time is money") as well as personal value, due to an awareness of the limited time in each day and in human life spans.

Stress in study Math? Now time to you RELAX With this all math time game!!!
ENJOY!!!
Stop The Clock(Click Here To Play)
In this
game from Oswego you have to drag
the times to match the analogue
clocks. There are five to match. When
you've finished, click Stop the Clock to
check your answers. The image on the left
links to the o'clock game, but there are
also games including 30 minutes, 15 minutes, 5 minutes and 1 minute intervals and
even a 24-hour clock
version.
Clock Works(Click Here To Play)
In this game aimed at KS1 you have to help
Max and Molly to fix the tower clock by
answering time questions. Some are quite easy,
just matching the o'clock time to a digital
clock. Other questions are harder, such as
"What time will it be in 11 hours?" There are
three different levels. BBC Schools.
Clock Wise Time Game(Click Here To Play)
In this BBC Education quiz game you have three levels to choose from. To practise o'clock times only, choose level 1. If you want to test your knowledge of 15 minute intervals on the clck, choose level 2. At level 3 you will be tested on times including 5 minute intervals. A time is displayed at the top and you click on the clock face
Time Clock Game(Click Here To Play)
Click the hour or minute button to advance the hands until the time on the clock face matches the digital clock time. Then click the check button. Netrover.
Bang On Time(Click Here To Play)
A fun telling the time game from Oswego. First you set the hand speed, from 1 to 15. Then on the next screen you are shown a time in words and you have to hit the button to stop the clock when the hands reach the correct time. This game would work well on an interactive whiteboard. It's really hard with the speed at its fastest setting, but not impossible!
Tell The Time Game(Click Here To Play)
There are three games to choose from here, all aimed at KS2. You have to stop the clock then enter the time. In the AM or PM game you have to enter the time and whether it's AM or PM. In the 24 hour clock game you have to stop the clock then enter the time n a digital 24-hour clock. BGfL.
Hickory Dickory Dock(Click Here To Play)
Click the grandfather clock which matches the time shown. If you get it right the mouse will run up and eat the cheese, but if you get it wrong the cat will catch the mouse. Includes o'clock, half past, quarter to and quarter past times. ICT Games.
Nash's Advanture(Click Here To Play)
In this game from Count On you have to help Marty the mouse to catch the right train based on the time Marty wants to arrive and the length of the journey.
Flick's Advanture(Click Here To Play)
An interactive story from BBC Schools for Key Stage 2 with questions on time to fill in as you go along, including how long a journey will take at a given speed in km/hour.
Time Difference(Click Here To Play)
This activity from BGfL takes KS2 students step-by-step through the process of calculating the difference between two times, using a time numberline.
