Reply To: Lesson 3 – Why The Unit Of Measure Matters – Discussion

[Lauren Teather]

In an earlier reflection I shared about a project where students are designing a conservation area for endangered species and how student completely misjudged the size of their designs because of the unit. They were using the grid squares on their maps to design without paying attention to the scale – 1 grid square = 20 m…. this caused a lot of confusion because the unit of measure matters. This ties perfectly into spatial reasoning and the idea that students need a conceptual understanding of measurement in order to make sense of unitizing! Great lesson!
