Length and height - Measure length 2 - Presentation

The "Measure Length (2)" lesson plan, aimed at enhancing students' understanding of measuring length and height, encourages the use of standard measures. The term 'standard measure' is discussed, prompting students to think about its meaning and the importance of using consistent units of measurement such as centimetres. The lesson includes a series of activities where students are asked to measure various objects, such as building blocks, toy trains, and chocolate bars, using a ruler. They explore the significance of the numbers on the ruler and the correct starting point for measuring an object to ensure accuracy.

Further activities challenge the students to compare lengths and heights by measuring different coloured straws and strings, determining which is the tallest or shortest. The lesson also includes reasoning tasks, such as evaluating whether a peer, Malachi, has measured the length of a crayon correctly, and deducing the possible length of a lost ribbon based on comparisons with others. Independent work reinforces the skills learned, as students use rulers to measure the lengths of various objects and engage in true or false questions to demonstrate their understanding. The lesson concludes with a discussion on how rulers, akin to number lines, facilitate the comparison of object sizes and the practical application of measuring skills.
