Are you dreading teaching your students the different strategies for dividing decimals? There are so many types of decimal division problems!

Well, I’m breaking it down for you in easy-to-teach mini-lessons for each type of division problem.

**Types of Dividing Decimals Problems**

#### Dividing Decimals…

- by whole numbers
- dividing whole numbers by decimals
- by decimals
- with the same number of decimal digits in both the dividend and divisor
- with a different number of decimal digits in both the dividend and divisor
- annexing zeros

- with visual models

# How I Teach it In the Classroom

**How You Can Teach it Digitally**

Is your school remote or using a hybrid model?

* You can do everything above digitally*. To intervene with students, you can meet with small groups virtually to re-teach.

Each of the mini-lessons, including their practice activities and exit tickets, as well as the quiz, are also available in a digital form. Mini-lessons and practice activities are provided in Google Slides. In addition, a tutorial video is included in each mini-lesson that takes students step-by-step through the example problem from the guided notes. Parents will find it helpful to have a clear guide to each of the problems along with the video (especially for the visual models!).

# Common Misconceptions

When there’s a decimal in the divisor, students sometimes will:

- not move the decimal in the divisor
- forget to place the decimal straight up into their answer (after moving the decimal in the divisor and dividend)
- move the decimal in the divisor, but not the dividend
- move the decimal in the dividend, but not the divisor,
- move the decimal point a different number of times in the dividend and divisor to make them each a whole number
- have trouble understanding that they’re really increasing both the dividend and the divisor by the same power of ten, as opposed to thinking of it as “moving the decimal” – this is important to clarify as you’re teaching

**Need More Help?**

I even have a PDF that you can e-mail out to parents with links to the tutorial videos. If they’re struggling to help their child at home, the videos will provide step-by-step directions to solve each type of decimal division problem.

Watch the tutorial videos to see two dividing decimals examples (with visual models and the standard algorithm – tenths and hundredths).
