I have my students start off with measuring things with standard 1 cm cubes. They use this to build a 30 cm ruler, though they don't realize this. We talk about what they notice and what we can do to make it easier to measure. Then I use the orange cuisinare rod, which is 1 dm or 10 cm, and we compare this to the ruler and record our observations. They then have to figure out how many orange rods fit a 1 meter string and then make a strip of paper that measures that distance. Students through exploration find out that the metric system is based around place value of ten.

The next exercise is to use calculators to find rules for multipling and dividing by power of ten. Then I teach them the acronym for the metric system: Kings (Km) Henry's (hm) Daughter (dam) must drink(dm) chocolate (cm) milk (mm)

Hopes this helps.

Hi! Thanks for the suggestions. Are the cuisinare rods the 10 place value rods?

They are different then the tens place rods, they come in different colours and all represent different fraction amounts. At least I think they are different. But you can still use the base ten and the ones it should be the same measurement.
