Do you remember the fate of poor King Henry? In the space below, see if you can type the phrase we learned - or as much of it as you remember.

Open Ended

So far, we have looked at the following units of measurement:

millimetre, centimetre, decimetre, metre, kilometre

What do all of their names have in common?

Multiple Choice

When we look at the measurement model (with King Henry), what unit was in the middle?

• kilometre

• speedometre

• decimetre

• metre

We're going to watch a short video on "The Meter". Have a look at our Meet screen.

Learning Goal

I am learning about the meaning of metric prefixes and the relative size of different metric units.

Some text here about the topic of discussion

Fill in the Blank

The prefix "milli" means one-thousandth.

How many millimetres are in one metre?

Fill in the Blank

The prefix "centi" means one-hundredth.

How many centimetres are in one metre?

Fill in the Blank

The prefix "deci" means one-tenth.

How many decimetres are in one metre?

Fill in the Blank

The prefix "deca" means ten.

How many decametres are in one metre?

Fill in the Blank

The prefix "hecto" means hundred.

How many hectometres are in one metre?

Fill in the Blank

The prefix "kilo" means thousand.

How many kilometres are in one metre?

We can think of this in terms of place value

Some text here about the topic of discussion

​kilo	hecto	deca	METRE	deci	centi	milli
​1000	100	10	1	1/10	1/100	1/1000

cent = 100 = centi

mille = 1000 = milli
