This lesson plan for 2nd graders focuses on measurement concepts, including units for length and weight, and how to measure objects accurately using various standard and nonstandard units. Students will learn to use body parts for nonstandard measurements like handspan and foot span, as well as standard units like meters and grams. The lesson aims to familiarize students with the tools and methods for measuring length and weight correctly.

1. UNIT 3-LESSON 1 :
Measurement:How
Heavy and How
Long?
Prepared by: T. Jessica
2nd Grade

2. 01 Identify the different standard units of
measurement.
02 Choose the proper unit to measure the
length and weight of an object.
03 Measure the length and weight of an
object correctly using the proper units and
instrument.
OBJECTIVES
At the end of this lesson, students will be able to:

3. What are the
different words
that are related
to measurement?

4. MEASUREMENT
●Measurement is a system to
measure the height, weight,
length, capacity or even amount
of certain objects. We can
measure how long things are or
how tall or how far two things are.

5. Nonstandard
and Standard
Units of
Measurement

6. Nonstandard Unit of
Measurement
●The measurement using the body
parts of the person
●The body parts like arms, hands,
feet, and elbows are used for this.

7. Nonstandard Unit of
Measurement

8. Handspan Measurement
Handspan measurement is
done using the palm of the
hand. The distance between
the tips of the thumb and the
tips of the little finger on an
open palm is taken into
account.

9. Cubit Measurement
The cubit length or the length from the
elbow to the tip of the fingers can be
used to measure length. The cubit
measurement can be used to measure
objects like clothes, tables, beds and
chairs but cannot be used for the longer
distances of large objects like walls.

10. Foot Span Measurement
The foot span measurement is done by
the tip of the toe and the heel of the
foot. The floor can be measured using
this type of measurement but it would
be very time-consuming. The length of
the foot is different for every person and
the measurement done using this can
vary.

11. Pace Measurement
Pace measurement or stride measurement is
taken by placing the right foot forward followed
by the left foot. The footsteps can be counted
easily and large distances like the distance from
school to home can be measured using pace
measurement. But if there is a change in the
length of the pace being followed, then it could
lead to a wrong calculation of the distance.

12. Arm Span Measurement
Arm span or wingspan or written arm span is
the physical length measured from one end of
an individual's arms (measured at the fingertips)
to the other when lifted parallel to the ground at
shoulder height at a 90 angle.
We'll use our arm span as a reference to
measure the length of the fabric. When
determining height, the arm span is sometimes
used.

13. ESTIMATION
Finding a number that is close to
the correct answer

15. Standard
Units of
Measurement

16. Standard Unit of
Measurement
●The length measured using the metric
system or using the defined units
comes under the standard way of
measurement.
●In these units like meter, kilometer,
centimeter, decagram, and
milligram are used.

17. Measuring
Tools

18. MEASURING LENGTH
 Length tells you how
long or short an object is

19. MEASURING LENGTH
 marked in
centimeters (cm)
and inches (in)
 Centimeters (cm) is
the unit of length
RULER

20. Steps to measure the correct
length using a RULER
1. Place the object on a flat surface.
2. Place the zero mark of the ruler at one
end of the object.
3. Place the object along the edge of the
ruler.
4. Check the other end of the object.
5. Read the mark where it ends.

21. MEASURING LENGTH
 marked in
centimeters (cm)
 One (1) meterstick
= one (1) meter
METERSTICK

22. MEASURED IN CENTIMETERS OR
METERS?

23. MEASURED IN CENTIMETERS OR
METERS?

24. MEASURED IN CENTIMETERS OR
METERS?

25. MEASURED IN CENTIMETERS OR
METERS?

26. MEASURED IN CENTIMETERS OR
METERS?

27. MEASURING WEIGHT
 Weight tells you how
heavy or how light an
object is

28. Which is heavy? Which is light?

29. MEASURING WEIGHT
 The common units for
weight are gram (g) and
kilogram (kg)

30. MEASURING WEIGHT
SCALE
 A scale or balance can
be used to determine
the weight of an
object.

31. Steps in using the SCALE
1. Clean the top of the scale with a piece of
cloth.
2. Place the object to be measured on top of the
scale.
3. Read the measurement in the scale.

32. MEASURED IN GRAMS OR
KILOGRAMS?

33. MEASURED IN GRAMS OR
KILOGRAMS?

34. MEASURED IN GRAMS OR
KILOGRAMS?

35. MEASURED IN GRAMS OR
KILOGRAMS?

36. MEASURED IN GRAMS OR
KILOGRAMS?
