Measurement Length and Perimeter - Kilometres - Worksheet

The worksheet titled "Length and Perimeter - Kilometres" is designed to help children understand and convert between different units of measure, specifically between kilometres and metres. To achieve fluency and precision in this area, the worksheet provides a variety of exercises. Children are expected to multiply and divide by 1,000 to convert between the two units, applying their skills in adding and subtracting four-digit numbers to find sums of lengths that equate to whole kilometres. The worksheet encourages the use of bar models to aid understanding, especially when finding fractions of kilometres, a skill built upon from Year 3 knowledge.

The worksheet also poses key questions to stimulate critical thinking and real-world application, such as researching the distances of different athletic races and converting those measurements. Children are tasked with solving problems that involve completing bar models with missing measurements, ensuring that they understand the equivalence of 1,000 metres to 1 kilometre. Additionally, they compare lengths using symbols to indicate greater than, less than, or equal to. The worksheet is differentiated to cater to various levels of ability, with tasks ranging from finding missing parts in a maze to solving more complex reasoning problems with harder numbers. This structured approach aims to deepen the students' understanding of length and perimeter measured in kilometres and metres.
