This was inspired by a task from Don Steward: https://donsteward.blogspot.com/2014/12/algebraic-product-puzzles.html
I wanted some similar puzzles on Quadratics that were more accessible to weaker students, without any negative terms, so that’s what I created!
Students have to fill in each blank cell with a bracket so that every row and column multiplies to make the quadratic expression at the end. Of course this could be done by random trial and error, but it makes much more sense to factorise the Quadratics!
An example is given on the sheet to help students understand how the puzzles work.
