AZ Teaching Standard: S4C4 PO2. Apply measurement skills to measure length, mass, and capacity using metric units.
Lesson Outcome: TSW estimate and accurately measure given objects and drawn lines using appropriate metric units.
Evidence: TSW estimate and confirm by accurately complete a table by measuring 6 objects and 4 drawn lines using metric units.
Big Idea: Accuracy of measurement affects decisions.
Materials: meter sticks, metric tapes, & metric rulers, various objects to measure (books, supplies, door, window, teacher)
