Distributive Property for Division

The distributive property for division basically means you can split your quantity up into smaller chunks that are easier to divide.

Let’s take 176 ÷ 8 as an example. It’s easier for students to consider questions in context, so think of putting 176 apples into bags of 8.

If we take the first 80 apples, then it’s easier to see that would be split up into 10 apples into each bag.  80 ÷ 8 is a much easier question.

The next 80 apples are divided up, adding another 10 to each bag.

That leaves 16 apples, which when divided up into 8 bags makes 2 each.

So what we’ve done is split 176 ÷ 8 into

80 ÷ 8

80  ÷8

16 ÷ 8

 

Once students have done this with various contexts, they can practice with numerical situations.  Daily oral / mental math time is perfect for this.  Some questions should have remainders.

  6. Hi. I see that you don’t update your page too often. I know
    that writing content is boring and time consuming.
    But did you know that there is a tool that allows you
    to create new articles using existing content (from article directories or other pages from
    your niche)? And it does it very well. The new articles
    are unique and pass the copyscape test. You should try miftolo’s tools

  7. I have noticed you don’t monetize your page, don’t waste your traffic, you can earn extra cash
    every month. You can use the best adsense alternative for any type of website (they approve all websites), for more details simply search in gooogle: boorfe’s tips monetize your website
