What is 17 x 5?
17 x 5 = 85
10 x 5 = 50
7 x 5 = 35
50 + 35 = 85
If we have the equation 8 x 36 = n, what is another way to write that equation?
A. n = 8 + 36
B. n = 8 x 42
C. n = 36 + 36 + 36 + 36 + 36 + 36 + 36 + 36
D. n = 42 + 50 + 36 + 16
Another way to write the equation 8 x 36 = n is:
C. n = 36 + 36 + 36 + 36 + 36 + 36 + 36 + 36
Student Council is making Thanksgiving Day cards with for a local nursing home. They are making them in batches of 70 and 80. If they make 6 batches of 70 cards, how many cards to they make?
Student Council would make 420 cards.
6 x 70 = 420
There are 9 friends in a Lego Creations Club. They shared 150 Legos equally for their creations. How many Legos were left over?
There are 6 Legos left over.
150 ÷ 9 = 16 R6
16 x 9 = (10 x 9) + (6 x 9)
16 x 9 = 144
144 + 6 (the remainder) = 150
What is 52 ÷ 4 ?
What is 52 ÷ 4 = 13
4 x 10 = 40
4 x 3 = 12
40 + 12 = 52
What equation represents the larger array made by these two smaller arrays?
A. 36 x 6 = 216
B. 30 x 8 = 240
C. 36 x 5 = 180
D. 30 x 10 = 300
The equation for the larger array made by these two smaller arrays is:
C. 36 x 5 = 180
Let's say that there are 92 fourth graders. If there are 4 fourth grade teachers, how many students would be in each class?
There would be 23 fourth graders in each of the 4 classrooms.
92 ÷ 4 = 23
23 x 4 = 92
20 x 4 = 80
3 x 4 = 12 80 + 12 = 92
There are 103 fourth graders signed up to go to the state museum. Parents with minivans are providing the transportation. If each minivan holds 7 students, how many minivans will they need to go to the museum?
They would need 15 minivans to take the trip to the state museum.
103 ÷ 7 = 14 R5
We wouldn't tell the 5 remaining students that they couldn't go on the trip, so another van would be needed to take all of the fourth graders.
What is 3 x 35?
3 x 35 = 105
3 x 30 = 90
3 x 5 = 15
90 + 15 = 105
Choose the TWO equations that can be used to find 6 x 81
A. 6 x 81 = 6 x (80 + 1)
B. 6 x 81 = 6 + (80 + 1)
C. 6 x 81 = (6 x 80) + 1
D. 6 x 81 = (6 x 80) + (6 x 1)
The TWO equations that can be used to find 6 x 81 are:
A. 6 x 81 = 6 x (80 + 1)
and
D. 6 x 81 = (6 x 80) + (6 x 1)
Thomas is training for a marathon. He runs/jogs 97 miles each month. How many miles does Thomas run/jog in 6 months?
Thomas would run/jog 582 miles in 6 months.
97 x 6 = 582
90 x 6 = 540
7 x 6 = 42
540 + 42 = 582
Sam is making a SEVERAL batches of bright blue slime. He needs 4 cups of glue for the recipe that he is using. How many batches can he make if he has a total of 35 cups of glue?
Sam can make 8 batches of bright blue slime.
35 ÷ 4 = 8 R3
With this problem, we need to ignore the remainder, because he doesn't have enough glue to make another batch of slime.
What is 15 x 12 ?
15 x 12 = 180
10 x 12 = 120
5 x 12 = 60
120 + 60 = 180
There are 37 fourth graders entering a poetry writing contest. Each student writes 4 poems. Which expression shows how to find the total number of poems that were written?
A. (4 x 30) + 7
B. (4 x 30) + (4 x 7)
C. 4 + (4 x 30)
D. 4 x 30 x 7
The expression that shows how to find the total number of poems that were written by the 37 fourth graders is:
B. (4 x 30) + (4 x 7)
Three friends are sharing 51 new Emoji pencils. How many pencils will each person get?
Each of the three friends will get 17 Emoji pencils.
51 ÷ 3 = 17
17 x 3 = 51
10 x 3 = 30
7 x 3 = 21 30 + 21 = 51
Sarah is packaging 29 muffins into boxes for a bake sale. Each box holds 6 muffins. How many boxes does Sarah need to hold ALL of the muffins?
Sarah would need 5 boxes to hold ALL of the muffins.
29 ÷ 6 = 4 R5
Based on this question, she would need that extra box for the remaining 5 muffins. She wants ALL of the muffins in boxes.
