Worksheet 1

MEASUREMENT OF LENGTH  

A. Objective

1.    Students can use instrument of measurement

2.    Students capable to measure the length of the objects in around using standard unit and nonstandard unit.

B.  Introduction

Did you ever measure the length of the table using the span of your hand? Then what happens if the measurement is done by more than one person?

Did you ever measure the table using a ruler? Then what happens if the measurement is done by others?

It’s will we discuss in this observations "Measurement of Length”
