Hi Zoe!

12

X12

------

If you are writing this problem out by hand, be sure that your numbers are lined up, like above. This will help you in making sure that you solve each step of your problem properly.

First, start with the 12. Multiply 12 by the "2" in the one's place, in the second number:

12

X 2

-----

Begin by multiplying 2 X 2 first, in the "ones" column.

Do you have 2X2=4? Great! Put the 4 in the ones column, where your answer would go.

Next, multiply 2 times the 1 digit. The 1 is actually a 10, because it is in the "tens" column.

2 X10=20

Place your 2 in the "tens" column--It should look like this...

12

X 2

-----

24

Since you are finished with the "ones" place, now you will work with the tens column.

put a zero under the 4 in 24.

then continue like this

12

X12

-----

24

120 because 12 X10=120

------

144 If you add 24 +120, you should have 144.

If you have a slightly different way of doing this problem, that's OK. The point is to get the correct answer.

If you have a times table, you can check yourself.

12 X12=144

Have a great week, Zoe!

Hi Zoe--

It's 144, but do you know why? Check this out:

Take a piece of lined paper, like writing paper for school.

On one line, write 12 letter Z's, like this:

then for the next 11 lines under it, do the exact same thing--12 Z's

So when you're done, you've made **12 Z's** **12 TIMES.**

It's going to look like this:

Now, carefully count them all--you can even circle each one as you go.

Did you get 144? Good--go show mom that you know it. :-)

All best,

Matt in NY

Hello Zoe!

well, let's try this by writing it out

12

x12

-----

24 - we know this is 24 because we multiplied the 2 on the bottom right to both of the top numbers

120 - we know this is 120 because we put a 0 to hold our place then we multiplied 1 on the bottom left to the top numbers

-----

144 - we know this is 144 because we added 24 + 120 = 144

So 12 x 12 = 144

Hi Zoe,

12 x 12 = 144
