How do you break up the numbers in this problem using the area model? 43 x 7
(40 + 3) x 7
100
Without using numbers, describe what goes in the YELLOW box? 
The answer, or product
100
What is this?
A multiplication table
100
How many DIGITS will be behind the decimal as you find the product to 3.4 x 5.1?
2 digits
100
When dividing with decimals, I can think of the numbers as whole numbers once I....do what?
Bring "up" the decimal directly above where it is in the "house."
200
It is the answer to double 12.
24
200
What is the original problem represented in the area model below?
17 x 14
200
What NUMBER goes in the RED box? 
1, or really a 100
200
Which property of multiplication do you apply as you use the Partial Product Method of multiplication?
Distributive
200
How many DIGITS will be behind the decimal as you find the product to 0.08 x 798.023?
5 digits
200
What are the first TWO steps to solving this problem? 
1) bring up decimal, 2) ask "how many times does 4 fit into 4?"/ put a 1 above the 4 in the quotient spot
300
It is the answer to double 8 plus double 8.
32

What product should go in the RED LINED section? 
40
300
What number goes in the BLUE box? 
A zero
300
What are the 5 properties of multiplication (that we know)?
Associative, Distributive, Commutative, Identity, Zero, OPTIONAL: Inverse
300
What is the product of 0.3 x 0.5?
0.15
300
What do you need to do BEFORE solving this division problem? 
"whoop" the decimal in the divisor spot (1.7) over one PV spot, aka multiply it by 10; then do the SAME to the 9.01. New problem is 90.1 divided by 17.
400
It is the answer to 5 squared minus 4
21
400
What is the ORIGINAL PROBLEM represented in this area model?
36 x 43
400
Why is there a zero in the blue box?
Because it's a place holder telling you that 2 is not really a 2, but a 20
400
What is the INVERSE of 3?
1/3
400
What is the original problem depicted in this image? 
4 tenths of 4 tenths
400
How do you eliminate the decimal in the divisor spot? 
Whoop it over TWO place value spots; you MUST do the same to the dividend. New problem is 1,001.1 divided by 235
500
Using estimation, what is a reasonable product? 5,497 x 70
350,000
500
What is the PRODUCT? 
1, 548
500
What's the product? Write on PAPER or WHITEBOARD and hold up to show your process. 
2, 046

500
What is the product? 
0.16
500
Is 9.01 divided by 1.7 equivalent to 90.1 divided by 17? Why/why not? 
YES, because you multiply BOTH the 9.01 and 1.7 by ten, or "whoop" the decimal one PV spot, to get 90.1 and 17
