Geometry Odd One Out

The "Odd One Out" activity is a thought-provoking exercise tailored for Year 5 students studying Geometry. Each slide in the presentation features a selection of images and terms that are relevant to the Geometry curriculum. The objective is for pupils to identify the item that does not belong with the others and to articulate their reasoning behind their choice. This process is not only about finding the correct answer but also about fostering a deeper understanding of geometric concepts through discussion. The activity encourages the use of precise mathematical vocabulary and serves as an excellent tool for either kickstarting the lesson as a starter activity or wrapping it up as a plenary.

For example, one of the slides presents four different types of angles: acute angle, obtuse angle, right angle, and left angle. Students are tasked with determining which term is the odd one out and explaining why. Another slide offers the words parallel, perpendicular, parallelogram, prism, and diagonal, prompting a discussion on the properties that distinguish these terms from one another. The activity is designed to be open-ended, with several potential correct answers, allowing for a variety of perspectives and explanations. This flexibility in the activity ensures that students are actively engaged and applying their knowledge of Geometry in a meaningful way.
