Read, write, and compare decimals

Yesterday and today, I worked on chapter seven: Read, Write, and Compare Decimals of my current project, How to Help Your Child with Fifth Grade Mathematics.

I will publish this chapter in the next version on July 5, 2013.

In the meantime, I want to point out a couple of websites that you might find helpful.

I have already added this to to my blogroll, but it’s worth mentioning. It is called A Maths Dictionary for Kids. It does use Flash, so it doesn’t work on my iPad, but I use it all the time on my laptop.

Specifically, click where it says “Enter Dictionary Here”. From there, click on the letter “E”, which will show all the dictionary entries that begin with that letter. Then click on “expanded notation”.  In the entry itself, there is a box where you can type in whole numbers and it will show you what they look like in expanded notation. FYI: expanded notation is the same as expanded form.

It won’t work for decimals, which your child in fifth grade will have to do, but it’s still helpful.

The other page is called Convert numbers into words. It gives you many options, including:

  • Convert Dollars and Cents into words
  • Convert Cardinal Numbers (integers) into words
  • Convert Decimal Numbers into words
  • Convert Ordinal Numbers into words

These are all useful, but “Convert Decimal Numbers into words” is perfect for working with this Common Core Standard for Mathematics.
