Using a physical or diagram model of the Sun, the Moon, and the Earth to explain the reason for seasons

The way that Earths axis is tilted is what determines the season that it is. for example when the Northern hemisphere tilts toward the Sun, it's summer in the Northern Hemisphere. And when the Southern hemisphere tilts toward the Sun, it's winter in the Northern Hemisphere. This is because when a hemisphere is tilted towards the sun, that hemisphere is getting direct rays from the sun.

Step-by-step explanation:

Multiplication and division of whole numbers throw up many surprising things. This module encourages multiplicative thinking about numbers, and introduces ideas that are essential skills in fractions and algebra.

The ideas of this module are presented in purely arithmetical form, and no algebra is used except in some remarks that look forward to later work. The only numbers in the module are whole numbers, apart from the final paragraphs, where fractions are used so that the fifth index law can be presented in a more satisfactory form.

Students first meet the distinction between odd numbers and even numbers in early primary school, but it is useful everywhere in mathematics. Even numbers are multiples of 2, and more generally, multiples arise throughout mathematics and everyday life. The mass of a stack of bricks is a multiple of the mass of one brick. The number of pages in a packet of notebooks is a multiple of the number of pages in one notebook.

The factors of a number can be displayed using rectangular arrays. Some numbers, such as 30, can arise in many different ways as a product,

30 = 1 × 30 = 2 × 15 = 3 × 10 = 5 × 6 = 2 × 3 × 5,
