The Value of the "Place"

It's the place that matters! We have been working on decimals which are part of our base-ten number system. The students were asked to represent mixed numbers as decimals using the base-ten blocks. In this case, the "flat" was used to represent one whole. We used the sticks and cubes for tenths and hundredths. The number below shows 3.6 (three and six-tenths). The students also wrote the numbers in expanded form below the block representation.

Our essential questions for this unit are:

How are fractions and decimals related?

How do we write and show decimals?

How do we write decimals in expanded form?
