4 Choosing an Appropriate Unit

Choose centimetres, metres, or kilometres to measure

Goal lengths and order lengths with different units.

At-Home Help

Sometimes lengths can be

measured using different units.

For example, you can measure

the height of a door in metres or

centimetres. Often, it is better to

measure in one unit than

another. Part of estimating and

measuring lengths is deciding

which unit or units to use.

1. Complete each statement using centimetres, metres, or kilometres.

a) An oak tree might be about 20 metres tall.

b) A forest might be about 4 kilometres long.

c) The trunk of an oak tree might about be 2 metres around.

d) An oak tree branch might be about 6 metres long.

e) An oak leaf is about 5 centimetres wide.

f ) An acorn is about 3 centimetres long.

2. Name 2 objects or distances that might have each length.

Answers will vary.

a) 3 km a hiking trail

distance to a shopping mall

b) 3 m length of a room

length of a wall unit

c) 3 cm width of a ruler

width of a cellular phone
