Length and Perimeter Target Board 1

The Year 4 Measures lesson plan introduces students to the concepts of length and perimeter, with a specific focus on converting between different units of measure and calculating the perimeter of rectilinear figures, including squares, in both centimetres and metres. The objective of Target Board 1 is to provide students with an engaging and practical way to reinforce their understanding of these measurements through conversion and calculation exercises. The target board serves as a versatile tool for quick maths sessions, ideal for either the start or end of a lesson, and is perfectly suited for retrieval practice to help solidify these concepts.

Target Boards are designed to be interactive and can be used with the entire class or smaller groups. Teachers display the board, and students use whiteboards and pens to respond to various challenges presented to them. These challenges might include identifying measurements less than a specified amount, such as 50mm, or finding two lengths of a rectangle that combine to create a perimeter exceeding a certain value, like 25cm. The boards feature an array of numbers representing lengths in millimetres, centimetres, metres, and even kilometres, allowing students to practise a wide range of maths skills. Teachers can easily differentiate the level of challenge by tailoring instructions to suit different groups, making the learning experience both inclusive and adaptable to varying abilities.
