Michiko breaks apart the equation 3 x 6. She writes: (3 x 2) + (3 x ___). What is the missing number?
4 (Because 2 + 4 = 6)
In the equation 6 x 7 = 42, is 42 a factor or a multiple of 6?
multiple
If you put the number 4 in the blank, is this equation true: 36 / ___ = 9?
True
Jami has 30 apples. She puts an equal number of apples into 5 bowls. Does this word problem represent 30 - 5, 30 x 5, or 30 / 5?
30 / 5 (Division)
Solve for the blank: 36 / ____ = 4
9
You need to multiply 6 x 5 x 2. According to the Associative Property, you can group 5 x 2 first. What is 5 x 2, and what do you multiply that answer by?
5 x 2 = 10. Then multiply 10 x 6 = 60
In the equation 6 x 7 = 42, is 7 a factor or a multiple of 42?
factor
25 is a factor of 5
False (5 is a factor of 25; 25 is a multiple of 5)
Marlon practices piano for 4 weeks. He practices 2 days each week, and 3 hours each day. What is the total number of hours he practices?
24 Hours. (Step 1: 4 weeks x 2 days= 8 days. Step 2: 8 days x 3 hours = 24).
Find the value of the question mark. Note: The question mark is the same number in both equations.
40 \ 8 = ?
8 x ? = 40
? = 5
Rafa has 7 plates with 9 cherries each. He splits them into two groups: 4 plates and 3 plates. Which expression matches this?
A) (4 + 9) + (3 + 9)
B) (4 x 9) + (3 x 9)
B
True or False: 25 is a factor of 5
False. (5 is a factor of 25. 25 is a multiple of 5)
The expression (3 x 5) + (3 x 4) is equivalent to 3 x 9
True (Because 5 + 4 = 9)
Patrick knows there are 10 tables with 4 students at each (10 x 4). He wants to use the Commutative Property to solve it a different way. What equation should he use?
4 x 10 = 40
True or False? If you put the number 4 in the blank, is this equation true?
28 / 7 = ___
True (28 / 7 = 4)
Combine this "broken" equation back into one simple multiplication fact: (8 x 2) + (8 x 4) = ?
8 x 6 (Add the 2 and 4 to get 6)
Explain how to solve 42 / 6 using multiplication.
Ask yourself: "6 times what equals 42?" (6 x 7 = 42)
5 is a factor of 40
True (Because 5 x 8 = 40)
Opal found 4 groups of animals with 5 animals in each group (4 x 5 = 20). If Opal finds 2 more groups of animals (Amphibians and Insects) that also have 5 animals each, how many animals would she have in total?
30 animals
Look at these three equations. If you put the number 4 in every blank, only TWO of them will be true. Which one is FALSE?
1. 36 / ___ = 9
2. 28 / 7 = ___
3. ___ x 8 = 24
Equation #3 is false
Which of these expressions is NOT equivalent to 3 x 9?
A) (3 x 5) + (3 x 4)
B) 3 x (4 + 5)
C) (3 x 3) + (3 x 3)
C is NOT equivalent
True or False: For every factor of 5 (which are 1 and 5), 5 is a multiple of that number.
True
The expression 3 x 4 + 5 is equivalent to 3 x 9
False!
