Solving simultaneous equations mastery style using bar models L2

This is the second lesson in a series of lessons designed as a visual introduction to simultaneous equations. This lesson is an leads on from the 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 the signs are different. (Positive ones and ones with different coefficients will be added as different resources in my library). The lesson includes fully animated examples to make concepts clear, a true/false task and looks to link in some decimals and fractions within the main task. 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. 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 the presentation 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.
