Length and Perimeter - Measure length - Starter

In the provided material for Year 3 students, the focus is on revising and strengthening their understanding of basic mathematical concepts, including length, perimeter, and properties of shapes. The lesson starts with a 'Fluent in Four' activity, which aims to build fluency in arithmetic through quick-fire questions. For instance, pupils are tasked with adding numbers represented in tens and ones, such as '30 tens and 8 ones', and then calculating a number that is '4 less than 5 hundreds'. These exercises help students practice their addition and understand the value of numbers in different forms.

Further activities require students to compare lengths using the symbols for less than (<), greater than (>), or equal to (=). They are presented with pairs of measurements, such as '42 cm' and '24 cm', and must determine the correct relational symbol to use between them. Additionally, they work on completing number sequences, enhancing their ability to identify patterns and predict subsequent numbers. The lesson also includes a task where students must fill in a table with the names of shapes and their corresponding number of edges, faces, and vertices. This part of the lesson is designed to familiarise students with geometric vocabulary and the properties of common 3D shapes, such as cuboids and cubes, and a square-based pyramid.
