Place value with decimals review

I want to take a few minutes to review some of the strategies we have explored this week in our unit on decimals.


First, let's talk about reading a decimal:

1) Label the numbers and your decimal

2) Put a 1 under the decimal point and put zeros under all digits to the right of the decimal

3) Add the letters THS to the end of the last zero

4) Read the number starting at the top, then read the bottom line.


This strategy can also be used to check your answer when changing from word form to standard form.


Next, let's talk about comparing and ordering decimals:

1) Line up your decimal points (stack 'em up)

2) Compare starting all the way to the left ( the highest place)

3) Pay attention to what you are being asked for ( greatest to least or least to greatest)

The only difference between comparing and ordering decimals is that comparing only deals with two numbers while ordering deals with more than two.

In my next post, I will review the strategies for working with whole numbers in preparation for our unit test on Friday.
