Best Value for Money - the Unitary Method WORKSHEET

This worksheet will guide your learners through comparing prices using unit scaling beginning with using direct proportion to find the cost of 1 unit when m units cost £n in section A.

Section B sees pupils scaling prices down to 1 unit and then scaling up to another amount.

The price comparisons start in section C and in section D special offers such as ‘buy one get one-half price’ are introduced

Students will work with volumes and mass as well as currency conversions throughout and will have to consider when rounding to the nearest penny is appropriate or not.
