### How to Find the Halfway Point

The whole numbers that are between 7 and 13 are: 8, 9, 10, 11 and, 12.

The difference between 13 and 7 is 6.

Half the difference is 3. 6 divided by 2=3

The number 10 is halfway between 7 and 13.

To find this out you can either add half the difference to the smaller number or subtract half the difference from the larger number.

The second way is to use a number line.

The third way is to add both of the numbers together and divide the sum by two. 13+7=20 20 divided by 2=10

1.) a. What are the whole numbers between 68 and 72? They are 69, 70, 71.
b. What are the whole numbers between 108.3 and 111.6? They are 109, 110, 111.

2.) a. What is the halfway point between 70 and 170? It is 120.
b. What is the halfway point between 1801 and 1813? It is 1807.
c. What is the halfway point between 18.4 and 6.2? It is 12.3

Sorry, I couldn't get the video to work so here is the link to get to the video. This video can help you if you have trouble dividing the difference. http://www.youtube.com/user/yourteachermathhelp#p/search/2/dcOOYtiGQJk

1. Great Job Emily, I like the pictureas and link that you put, next time you need to read how to do the blog so the video goes on properly, but other than that Great Job!

2. Great Post Emily!I especially liked the link and picture. I'm sorry the video couldn't work just try it again next time.Other than that the blog was very well done.

3. Great scribe post, Emily! The link really helped me and I liked the picture that you put on to show the numberline. You should read the notes for how to do the blog so you can put the video on properly. Other than that, great job!

4. I really like your post Emily. I think the links were good, and I like the way you changed the font on the important words, expectantly in
REMEMBER TO DO DO YOUR HOMEWORK.
Thanks for the reminder, I almost forgot. Again, great post.

5. Excellent post Emily! It was very neat and it help me understood finding the halfway point. There is nothing much I could say about this, except maybe you should list the homework we have just in case people forgot to write it down.

6. Nice post Emily. I like how you used a different color in some important words. I agree with Marie, you should write down the homework for some people who weren't there. I think Nikki wasn't there, but other than that, great post.

7. Nice post Emily!! Great job! i like how ou used different colors for the important words.Next time you should write down what was for homework so students that forgot and comment know that it was for homework,other then that great post!

8. Great post Emily!! It really helped me learn about what you did in class because I was not there. But I think that you should have included what the Homework was for people who are away.

9. Thanks for the helpful comments. For some reason when I tried to put the video in in the correct spot it wouldn't actually show the video so I had to put it as a link. Next time I post again I will try to put the homework on.

10. I was away today and do not know what the Homework is. Can some one please tell me?

12. Sorry guys!! I didn't really know how to word the question for the homework but a asked someone and I understand it now.
Here are the homework questions:
1. Is 38 closer to 30 or 40?
2. Is 3.4 closer to 6.6 or 0.6?
3. Is 0.732 closer to 0.641 or 0.891?
4. Is 78.22 closer to 77.77 or 78.68?

13. Great Post, Emily! I liked how you highlighted the important words, also the picture helps me too. The only problem i saw was the video, it couldn't work. But everything else was perfect!

GOOD JOB!

14. Good job Emily!but you could have looked before you posted the video.and thanks for
Telling us we had.but everything else was good.

15. Nice job Emily, i like the pictures you put and thank you for putting our homework.

16. Nice post Emily! I like how you used a different color for the important words and the reminder to do our homework. Also the link and the video looks fine. Next time you should put what's for homework but other than that everything looks fantastic!

17. Good job Emily,I liked the way you put the pictures and video to help us uderstand more about halfway points and how to find them. But I wished you put more space in your blog and thank you for puting our homework in the comment.Other then that everything was very well done.

18. Emily, you did a good job on the blog only one thing you could do next time is instead of putting " REMEMBER TO DO YOUR HOMEWORK", You could have put the homework your self. Last thing was you put that you couldn't put the video instead of not putting a video at all But overall Everything was fine. Great Job!

19. Nice post Emily, I liked your pictures showing us different ways to find the half way point. But next time try to space it out a bit more and write down what the homework was.

20. Great job Emily, I like how you changed the font on some of the words, maybe next time you should write what the homework was, but besides that great job!

21. Good job, Emily. I like how you changed the colour of the important words. It would be nice if you wrote the homework down. Other than that, it was really well done.

22. Thanks for all the comments guys!!!! I just read most of them and I will be sure to do the things you said to improve next time I post a blog.

23. If you have any questions about my post be sure to ask me.

24. Good job Emily! Everthing was good. But you should tell people what was home work.

25. Good job Emily you did a good job.

26. Great Post Emily! I liked how you changed the color for the important words. Next time you should put what the homework is.
