The purpose of this activity is to support students in recognising that scaling can be applied to comparisons where one amount is less than another. For example, a 3-stack of cubes is “four times less” than a 12-stack. The use of “times” in such situations might seem counter-intuitive for students who believe that "multiplication makes bigger".
