Properties of shape - Parallel and Perpendicular​ - Starter

In this Year 3 mathematics lesson, students are introduced to the concept of parallel and perpendicular lines. The lesson begins with a 'Fluent in Four' revision exercise, where students are encouraged to practice their mental arithmetic by solving a series of quick-fire maths problems. For example, they are asked to complete equations like '748 = 437 + ___' and compare numbers to determine which is greater, equal, or less by inserting symbols like '<', '=', or '>'. This activity helps to warm up their mathematical thinking and prepares them for the day's learning.

As part of the lesson, students are tasked with identifying horizontal and vertical lines in various images, reinforcing their understanding of these key geometric concepts. They are also challenged to label these lines correctly and to use their knowledge to solve problems involving number sentences and comparisons. Additionally, students explore fractions by determining what fraction of a shape is shaded, further enhancing their numerical skills. The lesson includes practical exercises such as breaking down numbers into hundreds, tens, and ones, and combining these to form new numbers, as well as working with addition to find the sum of numbers with specific conditions, such as '6 less than 3 hundreds add 8 more than 56 tens ='. These activities are designed to strengthen students' grasp of number properties and spatial awareness in a fun and engaging way.
