We will have about 1.5 weeks working with dividing decimals. If the students remember how to do regular long division, then dividing decimals is simple! You can go to the CoolMath.com page here to see the details and for more examples, but an example of the expectations for our students is below.
Dividing by Powers of Ten
To divide by 10, 100, or 1000, simply move the decimal point to the left as many spaces as there are zeros. Here is a video with examples:

Estimation & Decimal Placement
Students can use estimation to determine the placement of a decimal in an answer. For example, in the problem 11.95 ÷ 1.9 = 6 2 8 9, where should the decimal be placed? If you round to 12 and 2, you can use 12 ÷ 2 = 6 to determine that it should be placed between the 6 and 2 to make 11.95 ÷ 1.9 = 6 . 2 8 9.
