KS3 Algebra Starter Linear Equations - PowerPoint
A 5-10 minute KS3 starter to revise the solution of simple linear equations in one variable (with and without brackets). The solution to a riddle is given by solving 7 equations. Remember, before you put the riddle slide on the board, to tell the class not to shout out the answer, hands up only. This stops anyone who’s heard the riddle before spoiling the exercise.
