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.
OK, that was a little freaky, but it won't get any worse. You'll get it! Let's keep going!
Hey, we just finished the first chunk of steps! And it wasn't that bad! DMS! OK, now we're going to do the exact same thing, but with a different number...
Now, let's go back into our DMS loop using the 15!
Check it!! 25 x 3 should = 75! Yep! Go to the next page for another one! |
