Properties of Shape - Horizontal and Vertical - Starter

In a mathematics lesson designed for Year 4 students, they are presented with a variety of tasks aimed at revising their understanding of numbers and shapes. The 'Fluent in Four' revision segment begins with a subtraction problem that challenges students to calculate 3 thousands, six hundreds, 7 ones and four tens minus a number that is 2 less than seventy-seven tens. This arithmetic exercise helps reinforce their understanding of place value and subtraction. In another task, students are asked to identify which images are reflections, fostering their visual recognition skills and understanding of symmetry.

Additionally, the lesson includes activities that require filling in missing numbers to complete sequences, further enhancing their numerical fluency and pattern recognition. A more geometric aspect of the lesson involves ordering three different shapes by their perimeters, starting with the shape that has the greatest perimeter. Shape C is identified as a square, and students must compare it with two other shapes, which are not drawn to scale, to determine the correct order based on their perimeters. This exercise not only helps students practice measuring and comparing lengths but also solidifies their grasp of geometric properties and spatial awareness.
