Which can be used to examine types of angles such as acute,obtuse and reflex. The two clocks activity is excellent in this regard and Obviously can make reading the clock more difficult.įurther lessons on the telling the time involve comparison of two different times You can do this with other parts of the clock too, which So for example to change the colour of the numbers,Ĭlick numbers followed by a colour from theĬolourpicker. Select the style mode to access controls. Percentages can also be shown by clicking to toggle the percentage display. Mode and divide the clock according to the number selected. Essentially the clock is dividedĭepending on the simplified fraction. The default setting is auto, this divides the clockĪccording to the fraction displayed. The clock is divided according to the divider The hour and second hands to give a simplified view. Two large fractions are displayed the fraction of an hour shows the unsimplifiedįraction is the same fraction cancelled down when possible. In the fraction mode a circle sector is painted from 12 o'clock to the minute Past', 'half past' and 'a quarter to' obviously are linked to fraction. Select fraction on the mode control to use Also conversions such as 30 secs * 6 = 180° This helps learning of key angles such as 0°, 90°,Ģ70° etc.

Setting as children can see a full angle of 360° turned every Or measure the angle of the second handįrom 12 o'clock. You can choose the angle between the hour hand and minute hand, bothĬlockwise and anti-clockwise. Snaps to the nearest minute, turn this feature off by clicking snap. When dragging the minute hand it currently To display the angle click Ang, and click Arc The large clock hands can be made thin for better accuracy by clicking Use this to change the size of the protractor. Move the clock hands and the protractor willįollow. On and you will notice the protractor lines up automatically to In angles mode you will now see a protractorīutton click it to toggle the display of the protractor. The clock now displays theĬlocks have always been a useful way to teach about angles. To demonstrate this click reset, soīoth minutes and hours are zero. Now ask what the class what time will be in say 1hour and 25

So a brief example of how to use them would be click random Underneath reset button sets both back to zero. The second one the minutes that have passed. Has elapsed when showing the actual real time. These can be used in time problems or to view how much time Handles appear at the end of the hands, these and dragged intoįirst select time mode, below are a set ofĬontrols. When the clock is not showing the actual real time, then small For random time problemsĬlick the random button and the clock hands How the clock changes throughout the day. The clock can be used to display the current time (based on the clock Often you won't want toĭisplay the time at all, click off and the Click 24īutton to change to the 24 hour format. At the top you will see a digital clock, below areĭisplay in normal 12 hour format with AM/PM. Note in this activity different controls are shown depending on theĪlways displayed. The clocked can be altered to change colors and its overall styling. The third mode uses the clock as a way to help understand fractions. The second mode uses the the clock hands as a way of learning angles. The first demonstrates how to tell the time using an analogue clock. The clock for learning time has movable hands.
