Activity 1.9:
Aim: To make a link between making estimation and taking the actual measurement
Materials and Apparatus: Pencil and ruler
Instruction
1. Measure the length of a pencil (p cm).
2. Measure and record the length of a table using the pencil.
Length of table = number of pencil × p cm.
3. Measure and record the length of the table using a ruler.
Question
What is the difference between the length of the table measured using a pencil (estimated measurement) and the length of the table measured using a ruler (actual measurement)?
Answer:
The length measured by a ruler is more precise compared to the length measured by a pencil.
