Here's another one:
Set it up:
Remember, the DMS loop!
Division, then
multiplication, then subtraction... and we do this until we run out of
numbers!
Division:
We want to see how many times
3 will go into 7...
Hmm... It doesn't go in cleanly does it?
From our times tables, we know that 3
goes into 6 and 3
goes into 9. But, 3
doesn't go into 7. That's OK.
So, what does
3 go into that's a little less than
7? SIX!
Three
goes into 6 two times.
| So, 3
goes into 7 two
times... with a little left over. Put that
2 right above the
7: |
 |
OK, that was a little freaky, but it won't get
any worse. You'll get it! Let's keep going!
| Multiplication:
Multiply the 2
and the 3 and put the
answer right under the
7: |
 |
|
Subtraction: Do the
subtraction...
That's 7
- 6
= 1 |
 |
Hey, we just finished the
first chunk of steps! And it wasn't that bad!
DMS!
Division, multiplication, subtraction.
OK, now we're going to do the
exact same thing, but with a different number...
The first thing is to set it up:
Drag the 5 down.
That makes it a 15... |
 |
Now, let's go back into our
DMS loop
using the 15!
| Division:
We want to see how
many times 3 will go into
15... 3
goes into 15 five
times... So, we put that 5
right above the 5: |
 |
| Multiplication:
Multiply the 5
and the 3 and put the
answer right under the
15: |
 |
| Subtraction:
That's 15
- 15
= 0
We've use all the numbers...
the 7 and the 5... and we got a 0 at the end...
DONE! Woo hoo!
The answer is 25. |
 |
Check it!!
25 x
3 should =
75! Yep!
