This is a series of lessons designed as a visual introduction to simultaneous equations. The bundle of lessons consists of four lessons and a mini assessment at the end. The lessons are structured as follows: Lesson 1 - Positive coefficients which are the same Lesson 2 - Negative and positive coefficients that re the same Lesson 3 - Different coefficients Lesson 4 - A summary with mixed questions and problem solving The lessons includes fully animated examples to make concepts clear, true/false tasks and looks to link in some decimals and fractions within the main tasks. The lesson has taken inspiration from a mastery style and starts off heavily focusing on using visual bar models to represent the simultaneous equations and later on looks at how we can write this algebraically. The bar models are used to make concepts clear to students but gradually removed and the links between the diagrams and algebraic methods are made explicit. There is a plenary review all of the topics covered. A mention must be given to Pixi Maths as there are two slides at the beginning of L1 which were excellent and borrowed from a Pixi Maths PPT. Hope this is useful, please leave a review if it is or any constructive criticism.
