The number of simultaneous measures complicates our perception. Visually, we can easily draw a conclusion with a single linear measure. Secondly, comparing area requires experience to play and learn from different attempts and comparisons. Finally Volume, requires us to imagine (abstractly) even more. If students don’t regularly bake or manage liquid volumes how can they compare without experience?
Developmentally, I know Kindergarten kids love their sandboxes and filling cups. Too often the toys and tools are left in the primary classes and too quickly substituted with paper and pencil in higher grades.
When I am shopping, it drives me nuts trying to compare produces in various jars. Even when I read the volume label I have to fight my instinct not to grab the ‘taller’ jar. Marketers use so many games to mess with our perceptions.
