Length and Perimeter - Calculate perimeter - Starter

The 'Fluent in Four - Revision' exercises for Year 3 students, as part of their Spring Term curriculum in Week 10, are designed to bolster their understanding of basic arithmetic and geometry. On Day 1, students are challenged with a numerical problem that requires them to combine different place values: 1 less than 38 tens plus 4 hundreds and 97 ones, which equates to the sum of 379 and 497. They are tasked to determine the number represented by a visual representation of tens and ones, enhancing their grasp of the base-ten number system. Additionally, students are asked to order shapes based on the number of vertices they have and identify which images allow them to find the perimeter, applying their knowledge of shape properties and measurement.

Progressing to Day 2, the exercises continue to focus on numerical operations, such as addition, with students adding together ones and tens to find a total. They also practice subtraction by calculating 8 hundreds, six tens, and 1 one minus a number that is 4 more than 580. To develop their understanding of fractions, students are asked to identify whether a fraction has been coloured in equally and to mark with a cross if not. The lesson further delves into the practical application of mathematics by requiring students to calculate the perimeter of squares using two different methods, thus reinforcing their understanding of perimeter as the total distance around the edge of a two-dimensional shape.
