Properties of Shape - Drawing Lines and Angles Accurately - Planning

The Year 5 summer term lesson on the Properties of Shapes focuses on the precise drawing of lines and angles. Essential tools for the lesson include a ruler and a protractor, alongside supporting worksheets and a presentation. Key vocabulary terms such as angle, degree, right angle, acute angle, obtuse angle, reflex angle, length, centimetre, and millimetre are central to the lesson, with resources available to help students familiarise themselves with these concepts. The lesson begins with a review of converting centimetres to millimetres and understanding the degrees in different types of angles. Students are then challenged to draw lines to the nearest millimetre and use a protractor to measure and draw angles of specified sizes, ensuring precision in their work.

During the class, students engage in practical activities that include drawing lines and comparing their lengths, as well as drawing and summing angles using a protractor, with partner discussions to facilitate learning. A creative group work session involves analysing Kandinsky's artwork through a mathematical lens, identifying geometric properties such as straight, parallel lines and counting acute and obtuse angles. The lesson also addresses common misconceptions related to using rulers and protractors accurately. To consolidate their understanding, students reflect on their learning experience, articulating what they've learned, the skills they've used and found challenging, and the support that aided them. Differentiated worksheets cater to varying levels of proficiency, from basic angle and line drawing to more complex tasks requiring greater precision and depth of understanding.
