Algebra - Substitution - Starter

The Year 6 mathematics session for Spring Term, Week 5, Day 4, encompasses a variety of algebraic and geometric challenges to bolster students' proficiency in substitution, calculation of areas, and angle determination. The 'Fluent in Four' revision section encourages pupils to engage in arithmetic exercises such as dividing 856 by 8 and finding a quarter of 16, alongside decoding numerical phrases into standard numerical form. These activities are designed to warm up the students' mathematical thinking and prepare them for the more complex tasks ahead.

During this session, learners are introduced to two-step function machines, which require them to write algebraic expressions that represent the transformation of an input to an output by applying a series of operations. For example, multiplying the input by 3 and then adding 3 to find the output. The lesson also delves into geometry, where students are tasked with finding the area of a composite shape. They must draw a line to divide the shape into two parts, label them, and then calculate the area of each part before summing them to find the total area. Additionally, the lesson includes exercises on calculating missing angles in various geometric figures, reinforcing the students' understanding of angle properties and relationships. The hands-on approach to these problems helps to solidify the students' grasp of mathematical concepts through practical application.
