Length and height - Four operations with length - Presentation

In a series of engaging activities designed for students, the concept of the four operations with length is explored. These operations include addition, subtraction, multiplication, and division, which are applied to real-world scenarios involving measurements. For example, students are presented with characters like Tia, Zach, and Malachi, who each measure strips of paper and then perform various operations to determine differences in length, combined lengths, and the results of cutting or adding pieces. The tasks are designed to encourage practical application of mathematical operations in the context of length and height, enhancing students' understanding and fluency in these key areas.

Further activities deepen reasoning skills by asking students to solve problems involving the length of toys, such as a car and a fire engine, and to compare the height of different coloured bears. These exercises not only test students' ability to perform the four operations but also encourage them to reason and discuss the underlying mathematical concepts. Additionally, independent work tasks challenge students to use visual aids like bar models to calculate lengths and heights, promoting a deeper comprehension of how to apply the four operations in various situations. Key words in questions guide students to identify the correct operation to use, while the opportunity to create and answer their own questions fosters creativity and critical thinking in the learning process.
