# Estimating Lengths and Comparing Measurements (Primary 4)

MATHEMATICS

ASEI PDSI

THIRD TERM

WEEK 1

PRIMARY 4

THEME: MEASUREMENT AND GEOMETRY

PREVIOUS LESSON – SECOND TERM EXAMINATION MATHEMATICS BASIC 4

TOPIC: Estimating Lengths and Comparing Measurements

LEARNING AREA

Lesson One – Introduction to Measurement – Estimate and Measure the Length of Objects

Lesson Two – Conversion of Metres and Kilometres

Lesson Three – Addition and Substation in Metres and Kilometres

Lesson Four – Revision/Test/Quantitative Reasoning

TIME – 40 Minutes each.

LEARNING OUTCOME

By the end of the lesson, pupils should be able to:

1. estimate distances in kilometers and length in meters or centimeters and compare with measurements.

2. convert metres to kilometres.

3. convert kilometres to metres.

4. add and subtract length.

RATIONALE

Estimation is the decision made based on the available information or data. That’s, give an approximate or find something close to the correct answer. The object of measurement determines the object’s length (its comparison) and standard to the ruler or measuring tape.

The concept of Estimating Lengths and Comparing Measurements is to help students begin to see that using the same unit of measurement allows us to estimate, and estimation helps us give information to another person.

LEARNING MATERIALS

The teacher will teach the lesson with the aid of:

Tape

Meter rule, etc.

PREVIOUS KNOWLEDGE

Measurement and Estimation are part of our everyday routine. In the class (measuring and drawing of length), at home (measuring cups of rice, etc.), construction site (measuring length, width and height), in the market (yards of cloth materials), etc.
