Solving simultaneous equations introduction - mastery style using bar models

This is a lesson designed as a visual introduction to simultaneous equations. This lesson is an introduction and looks to master the skill of solving simultaneous equations when the equations have a set of variables with the same coefficient and when both variables are positive. (Negative ones and ones with different coefficients will be added as different resources in my library). The lesson includes examples, a true/false task and looks to link in some decimals and fractions within the topic. The lesson has taken inspiration from a mastery style and starts off heavily focusing on using bar models to represent the simultaneous equations and later on looks at how we can write this algebraically. A plenary review all of the topics covered. A mention must be given to Pixi Maths as there are a few slides at the beginning of the presentation which were excellent and borrowed from a Pixi Maths PPT and also to MathsPad where 3 scale type questions were borrowed.

Hope this is useful, please leave a review if it is or any constructive criticism.
