LESSON 4
READING SIMPLE METERS
In Lesson 3, you practiced telling time. Did
you know that you were reading a simple meter
Meters are devices used to measure things. You
could say a clock measures time. You may not
realize it, but you probably read other meters all
the time. We have to read rulers, timers, scales,
speedometers, and a number of things that
measure using numbers.
A common meter is the scale. Scales are
instruments or machines used for weighing. The
instruments must have a part that has marks to
show expected measures and a pointer. For
instance, the scales in a doctor’s office might look
something like this:
2 4 6 8 10 12 14 16 18 20
You never know when
you might need to
read a meter.
20 40 60 80 100 120 140 160 180 200 220 240 260 280 300
