Mathematics- representing decimal numbers…

Back in term 2 we related decimal numbers to fractions and even percentages. We compared them by placing them on a number line too. Today students represented them by using base 10 blocks we are all familiar with. The problem with base 10 MAB blocks is that they only go as small as one unit. Which is equal to a centi-cube. so what do we do?

We re name the ones we have. Students investigated and renamed one thousand block as the new unit (or ones), the old hundred block is now a tenth 1/10, the old ten stick is now a hundredth 1/100 and the old unit cube is now a thousandth 1/1000.
