Solve the following. Please ESTIMATE your answer before solving by rounding to the nearest ten. :)
136
+428
So, first you would round to the nearest ten. This would be:
140
+430
570
Then, you would actually add:
136
+428

If the "Rule" is "Subtract 6," what would the following numbers be?
In Out
6 ??
10 ??
23 17
?? 20
If the "Rule" is "Subtract 6," what would the following numbers be?
In Out
6 0
10 4

What is 3 x 6?
3 x 6 = 18!!!
Just like Lila has 18 new Fidgets. :)
100
What number model would go with this array?
Technically, there is ONE row of THREE.
So, the correct answer would be 1 x 3 = 3

How could you figure out the answer to 6 x 8?
HINT: You probably know 5 x 8......
So, 5 x 8 = 40 (Count by 5's eight times.)
Then, you just need to add eight!
40 + 8 = 48!
So, 6 x 8 = 48!!

?? 18
?? 25
If the "Rule" is "Add 5," what would the following numbers be?
In Out
3 8

What is 4 x 6?
4 x 6 = 24!!
Like the 24 times Graham talks about Purdue!
200
What would the number model be for this array?
Technically, there are THREE rows of FOUR.
So, the number model would be:
3 x 4 = 12!
200
How could you figure out the answer to 7 x 7?
Hint: Do you know what 5 x 7 is?
So, 5 x 7 = 35 (Count by 5's seven times.)
Now, we just need those last two seven's!
7 + 7= 14, so then we just need to add 35 + 14!
So, 7 x7 = 49. :)

-118
So, first you would round to the nearest ten. This would be:
430
-120

Then, you would actually subtract:
425
-118

What is 4 x 8?
4 x 8 = 32!!
Like some students need to take 32 bathroom breaks a day!

Make an array for 3 x 5. (THREE rows of FIVE.)
Make sure to not make an array for 5 x 3 because that would be a different array.
Your array should look something like this:
300
Which multiplication square is this array?
a.) 2 x 2
b.) 3 x 3
c.) 4 x 4
d.)5 x 5
Well, since there are FOUR rows of FOUR, that means the number model would have to be 4 x 4!
So, letter "c" is the answer!
If an array is a "multiplication square," that means it has the same number of rows AND columns.
400
Solve the following. Please ESTIMATE your answer before solving by rounding to the nearest ten. :)
732
-549
So, first you would round to the nearest ten. This would be:
730
-550
180
Then, you would actually subtract:

In Out
2 4
3 6
5 10
10 20
What is "THE RULE" for the following table? Come up with your own example.
THE RULE IS....... x by 2!!! (or times by 2)
Examples include:
7 14
100 200
400
What is 6 x 7?
6 x 7 = 42!!
42, the amount of coloring tools Briella has!

Make an array for 2 x 9. (TWO rows of NINE)
Please do not make an array for 9 x 2, as this will be a different array!
Your array should look something like this:
400
Which multiplication square is this array?
a.) 2 x 2
b.) 3 x 3
c.) 4 x 4
d.)5 x 5
Well, since there are THREE rows of THREE, that means the number model would have to be 3 x 3!
So, letter "b" is the answer!
If an array is a "multiplication square," that means it has the same number of rows AND columns.

MAKE TWO ARRAYS!!
One for 4 x 5, and another for 5 x 4!
So, your array for 4 x 5 (or FOUR rows of FIVE) should look like this:
And, your array for 5 x 4 (or FIVE rows of FOUR) should look like this:
500
4 x 4 Explain how these two arrays are related:
1.)
2.)
Well, the arrays both have EIGHT (8) total dots.
And, they are really the same array but are FLIPPED.
The top array is 2 x 4 (or TWO rows of FOUR.)
The bottom array is 4 x 2 (or FOUR rows of TWO.)
