Linear Measurement: Centimetres and Metres
Standard measurement arrives in Grade 2: centimetres and metres. Students who spent Grade 1 discovering why uniform units are needed now learn the units that the whole world has agreed to use. A centimetre is small and precise; a metre is large and practical. Estimation before measurement is not a formality: it is a skill that develops number sense and catches errors. A student who estimates 45 cm and measures 3 m has not just made an error, they have demonstrated that estimation is not yet connected to measurement.
