Converting and Comparing Units of Money - PowerPoint

In a Year 4 mathematics resource focused on money, students are taught how to convert and compare different units of currency. The lesson begins with understanding the basic conversion between pence and pounds, where 100 pence is equivalent to £1. This foundational knowledge enables students to convert pence to pounds by dividing by 100 and vice versa, converting pounds to pence by multiplying by 100. For example, to convert 200p to pounds, students would divide 200 by 100 to get £2, and to convert £2 to pence, they would multiply 2 by 100 to get 200p.

The resource also explains the concept of decimal notation in money, where pence are represented as hundredths of a pound. It is important that money is always recorded with two decimal places, for instance, £1.10 instead of £1.1. Practical exercises include converting given amounts of pence into pounds, such as 300p to £3, and pounds into pence, such as £4 to 400p. Additionally, students learn to compare amounts of money by converting them to the same unit, which simplifies the process of determining which piggy bank contains more money. The resource provides examples and exercises to reinforce this skill, including adding and subtracting money by converting all amounts into pence before performing calculations.
