This lesson explores how well students can solve and create linear equations, determining whether each side of the equation is equal. The lesson involves students creating their own equations and trying to solve the value of x. Students work collaboratively in attempting to solve the equation, deciding if there is always a solution. This involves the process of establishing and utilising rules. The lesson is accompanied by downloadable resources for teacher use.
