A small presentation explaining different units of measures and at the end there will be an exercise to check the understanding of the explanation

1. DISTANCES, SIZES AND MEASUREMENTS

2. Distance is the space, considered from a linear perspective, between
one person or thing and another.
The main units of distance are the centimeter, meter, and kilometer.
For example, it is the separation between one place and
another.
DISTANCES

3. The meter is the fundamental unit of length.
The meter in short form is written as a “m”.
For example, we use the meter to know how
much we measure (1.80m) or to measure
distances (the bakery is in 10m).
METER (m)

4. The kilometer is a unit of length widely used
to measure distances on the earth's surface.
One kilometer equals 1000 meters.
This unit can be abbreviated by the symbol
km.
For example, we use km to measure long
distances (A Coruña is 150 km away).
KILOMETER (km)

5. The centimeter is a very common unit
of length that is defined as one
hundredth of a meter. That is, 100
centimeters are equal to 1 meter.
We use the cm to measure very small
distances such as tables, pencils or
even our height as well as the meter
(John is 170 cm).
CENTIMETER (km)

6. The liter is the unit for
capacity, its symbol is “l”.
Like the meter, it has
other units such as the
kiloliter or the centiliter.
OTHER UNITS OF MEASURE
The kilogram is the
fundamental unit of
mass, its symbol is “kg”.
Like the meter, it has
other units such as the
gram or the centigram.
LITTER KILOGRAM

7. ● If we have 1 kg of wood to which unit does it correspond: distance, weight or capacity?
● Which is bigger than 100 centimeters or 1 meter?
● 1 liter of milk is the same as 1 liter of water?
● To tell the distance from my house to the school, what unit do I use?
● What weighs more 1 kg of straw or 1 kg of steel?
