Numerical quantities, calculations, and measurements can be estimated or analyzed by using appropriate strategies and tools.
Measurement attributes can be quantified, and estimated using customary and non- customary units of measure.
What does it mean to estimate or analyze numerical quantities?
When is it is appropriate to estimate versus calculate?
What makes a tool and/or strategy appropriate for a given task?
Why does “what” we measure influence “how” we measure?
In what ways are the mathematical attributes of objects or processes measured, calculated and/or interpreted?
How precise do measurements and calculations need to be?
