Measuring Length

Lina`s Family (Measurement) Class 1 Notes MathsMohit and Meeta are placing their pencils along the edge of the table top to measure the length of the table.
Mohit: Length of the table is the same as 10 pencils.
Meeta: Length of the table is the same as 14 pencils.
Their measurement is different because Meeta's pencil is shorter than Mohit's pencil.
For correct measurement, Mohit and Meeta both should have used pencils of the same length.

Edurev Tips: If two people measure the length of the same object using the same ‘standard length’, their measurement will be the same or nearly same.
