Max Maths, Year 2, Learn together, Measuring length in centimetres and in metres (1)
Maths Resource Description
In a Year 2 mathematics lesson, children explore the concept of measuring length using both non-standard and standard units of measurement. The lesson begins with a practical activity where Jade measures the length of a pencil with paper clips, which provides a hands-on approach to understanding length. This method of using paper clips allows children to visually grasp the idea of length and how it can be quantified by counting the number of clips used.
Following this, Toby measures the same pencil but uses a ruler, introducing the class to a more accurate and standardised method of measurement. The ruler is marked in centimetres, and the pencil is shown to be approximately 13 centimetres long. This comparison helps students to see the difference between non-standard and standard units of measurement and to understand why rulers are commonly used for measuring length. The lesson emphasises that centimetres can be abbreviated as 'cm', making it easier for students to read and write measurements. The class is then encouraged to discuss which method they think is easier for measuring length and to consider the reasons for their preference.
