Class 4 Maths Chapter 6, Measuring Length, transitions from non-standard handspans to standard centimetre (cm) scales and metre (m) tapes — measuring small objects, converting between metres and centimetres (1 m = 100 cm), and finding perimeters in Fencing and Lacing.
What Class 4 Mathematics Chapter 6 Covers
Centimetre Scale & Measuring Small Objects reads a 15 cm / 30 cm ruler accurately (including starting from a broken mark), estimates and measures fingers, pencils, leaves, and crayons in centimetres.
Metres, Centimetres (1 m = 100 cm) & Fencing/Lacing Boundaries measures student heights and classroom lengths with a metre tape, relates 1 metre = 100 centimetres (half metre = 50 cm, quarter metre = 25 cm), and calculates total boundary length for fencing gardens and lacing tablecloths.

FAQ
How many centimetres are there in 1 metre, half a metre, and a quarter metre?
1 metre = 100 centimetres (cm); half a metre (1/2 m) = 50 cm; and a quarter metre (1/4 m) = 25 cm.
How do you measure an object with a ruler if the ‘0’ mark is broken?
Place one end of the object at a clear whole-number mark (such as 2 cm), read the mark at the other end, and subtract 2 cm from that reading.
