Measuring Metric Length and Distance By Moira Whitehouse PhD, *Edited by Janet Hooks – Syms Middle School

Some of the tools used to measure length and distance are a metric ruler, a meter stick and a metric tape measure. Write the NAMES of each measuring tool in your notebook!

From SMALLEST to LARGEST, the METRIC units used to measure length & distance are: -millimeter (mm) --tiny things (eyelashes, ants) -centimeter (cm) –small things (pencil, bike, person) -meter (m) -- large things (rooms, buses, buildings) -kilometer (Km) -- HUGE distances (like miles, but not) Wagner T. Cassimiro "Aranha"' Write the abbreviations for each unit in your notebook!

It is important to know that: -10 millimeters (mm) = 1 centimeter (cm) -100 centimeters (cm) = 1 meter (m) *Every meter stick has 100 cm! -1,000 meters (m) = 1 Kilometer (Km) *So, 1,000 meter sticks would add up to 1 Kilometer!

18 mm1.8 cm We will start by measuring distance, first by finding the correct millimeter and then stating the answer in centimeters for “A” through “G”. First, “A”. Stated as centimeters
