Length and height - Compare lengths and heights - Presentation

In a series of engaging and interactive slides, students are invited to revisit the concepts of length and height, honing their ability to compare and describe the dimensions of various objects and living things. The lesson begins with a discussion about the differences between length and height, prompting students to use the terms 'taller', 'longer', and 'shorter' in context. For example, they are asked to compare the height of a man and a boy, using sentence stems to articulate that the man is taller than the boy, and conversely, the boy is shorter than the man. This exercise is repeated with different pairs, such as a deer and a mountain hare, and an ostrich and a giraffe, to reinforce the comparative language.

Further activities guide students to apply the same comparative language to lengths. They compare the lengths of pencils and crayons, determining which is longer or shorter. In another task, students are challenged to compare vehicles, exploring various ways to construct sentences using words like 'longer', 'taller', 'shorter', and 'same'. The lesson also includes reasoning exercises that encourage critical thinking. For instance, students are asked to improve inaccurate sentences comparing the height of two individuals and to devise methods to verify if two pencils are of the same length. Independent work and group discussions provide opportunities for students to practice their new skills, ensuring they understand how to use appropriate terminology when comparing lengths and heights in different contexts.
