Aim: How can the metric system help us make uniform

measurements?

Do Now: The smart board needs a new cover. What can we use to measure the smart board

with if we don’t have a tool?

Why do we measure?

• We cannot rely on observations made with only our senses. They aren’t accurate.

• Measurements help us gather information. • Exact measurements are important to

scientists.

What do we measure?

• Length• Mass• Volume

How do we measure?

Customary• Difficult to convert

between measurements.
