The Half and Differences between Numbers


The whole numbers that are between 7 and 13 are 8, 9, 10, 11 and 12.
The difference between 13 and 7 is 6.
13 - 7 = 6
Half of this difference is 3.
6 divided by 2 equals 3.
The number 10 is halfway between 7 and 13.
Like this:

7 + 3 = 10
Or...
13 - 3 = 10

Finding a halfway between numbers.

You can add the given numbers and divide it by two.
Like this..

70 and
170
70 + 170 = 240
And divide it by two. It equals
120.


And:





If you don't get it still, look at these examples we did during class...

1. What are the whole numbers between these given numbers?
68 and 72: The answer would be 69, 70, 71.
108.3 and 111.6: The answer would be 109 and 110

How? If you think of it as the alphabet, like, A B C, you know that
B is in between A and C.

  4. NICE POST MAYA!!! I liked the colours you chose because they weren't too bright, but the font should've been a little bigger. The picture was nice and clear but I think that you could've explained it because some of us weren't in class the day you were given the notes so it would've definently helped us understand the topic more. I also think that the website you gave us at the bottom wasn't that good becuase it didn't really have to do with the topic.

  7. Great job! I really understood what you did in class that day. I really liked how you showed the methods of how to find halfway numbers, and your link really helped! Did you do the green and red on purpose? Because it DOES seem appropriate for Christmas... :) However, please note that 7+13 does not equal 10. That is all.

  8. Great job! The post clearly explained what we did in math yesterday. It should help anyone who didn't get it to get it now. I liked how you included the different methods we talked about. I surely think you know that 7+13 does not equal 10. Through it all, awesome post!

  15. Maya, I think that you did a good job but I think you should have put in everything that we did in class. Also, I think you should separate your work out a like bit more so it is a little bit easier to read. On the other hand, I liked how you changed the color of your answers, other than keeping it the same color as you questions. Good job!
