Length and height - Adding lengths - Presentation

In a series of engaging teaching slides focused on Year 6 maths, students are introduced to the concept of adding lengths. The lesson is structured to enhance their skills in counting by 2s and 5s, as they tackle practical problems involving the addition of different lengths. The initial discussion prompts students to contemplate what it means to add two lengths together. This foundational understanding is crucial as they proceed to hands-on activities, such as adding the lengths of toy fences, where one fence measures 8 cubes and the other 6 cubes, leading to a combined length of 14 cubes. The lesson emphasises the real-life application of these skills, encouraging students to solve problems that they might encounter in everyday scenarios.

As the lesson progresses, students are presented with more complex tasks that involve adding lengths of common objects like crayons and paperclips, using rulers to measure accurately. For instance, they calculate that two blue crayons, each 10cm long, total 20cm, while two red crayons, each 6cm long, total 12cm. In another activity, they determine that four paperclips, each 2cm long, have a combined length of 8cm. The lesson also incorporates reasoning exercises, where students use cubes to measure objects like apples and gingerbread men, and explore concepts such as doubling, with the example of building blocks. Independent work challenges students to find the total lengths of multiple objects, reinforcing their understanding of length addition. Critical thinking is encouraged as they discuss the meaning of 'length', the method of adding lengths, and the use of tools like rulers for measurement.
