'Sun time' and 'clock time' are different. Sun time is based on the fact that the sun reaches its highest point (the meridian), in the middle of the day, and on the next day at its highest point, it will have completed a full cycle. However, the time between the sun reaching successive meridians is often different from clock time. According to clock time, from May to August, the day is close to 24 hours, but in late October the days are about 15 minutes shorter, while in mid February the days are about 14 minutes longer. For our daily routines, it is important to have a constant 'clock time' of 24 hours. This variation is called the 'Equation of Time' and shows the relationship between sun time and clock time. The variation has two causes; the plane of the Earth's equator is inclined to the Earth's orbit around the Sun, and the orbit of the Earth around the sun is an ellipse and not a circle. The National Maritime Museum website shows two separate graphs for these causes, and a third graph where they are combined to give the full correction.

An excellent fractions booster activity from BGFL. There are five levels to work through. In level 1 you simply type in the number of children to share the pizza and the pizza will be cut into fractions for you. At Level 2 you drag fractions to complete a fraction wall. In Level 3 you have to count the number of shaded squares and the total number of squares then type in the fraction (use a slash . 1/4). Level 4 introduces a fraction numberline for you to drag the fractions onto. Level 5 uses a pizza to illustrate fraction equivalences.
