* Estimating decimal sums

* Adding decimals

* Estimating decimal differences

* Subtracting decimals

* Solving decimal word problems

The second Unit on More on Decimals consists of 13 lessons on the following topics:

* Multiplying decimals by whole numbers

* Multiplying decimals by decimals

* Dividing decimals by whole numbers

* Rounding decimal quotients

* Dividing decimals by decimals

* Solving decimal word problems

My favorite part is the text rollovers at the top of the page in the second lesson.
