Raj is solving 238 ÷ 17. Here are his steps so far:
170 ÷ 17 = 10
238 - 170 = 68
68 ÷ 17 = 4
What is Raj's next step?

Aliza has a set of 125 friendship bracelets. She decides to split them equally between 4 of her closest friends and keep the leftovers for herself.
How many bracelets will she get to keep?
Aliza keeps 1 bracelet for herself.
125 ÷ 4 = 31 r 1.
Anita is solving 72 x 47. Here are her steps so far.
70 x 40 = 2,800
70 x 7 = 490
2 x 40 = 80
Complete her last step and solve the problem.
Her last step is 2 x 7 = 14
2,800 + 490 + 80 + 14 = 3,384
Add parentheses to make the equation true.
5 x 2 + 7 ÷ 3 = 15
5 x [(2 + 7) ÷ 3] = 15
42 ÷ (7 + 7) x 5

Choose 2 equations whose products that are greater than the product of 30 x 900.
1,000 x 20
70 x 400
1,500 x 20
13 x 2,000
70 x 400 = 28,000
1,500 x 20 = 30,000
(30 x 900 = 27,000)
Ms. Puche is sorting Aria's 544 Bark Box toys (yes, she's spoiled) into piles. If she puts 16 toys in each pile, how many piles will there be?
Bryson is solving 54 x 64. Here are his steps
50 x 60 = 3,000
4 x 4 = 16
3,000 + 16 = 3,016
Is Bryson correct? If he is not, solve the problem correctly.
Bryson forgot two steps:
50 x 4 = 200
4 x 60 = 240
If you add his four products, 3,000 + 200 + 240 + 16 = 3,456
Which travels faster: heat or cold?
Heat, because you can catch a cold!
Write an expression that matches the sentence, then solve.
28 plus the product of 6 and 12

A girl is sitting in a house at night. There are no lights on at all. There is no lamp, no candle, nothing, yet she is reading. How is this possible?
She is blind and reading Braille.
Daisy wants to solve 322 ÷ 14 by breaking 322 apart into smaller pieces that are easier to divide by 14.
Write out the steps she can take to solve this problem. You can draw a picture if it helps.
280 ÷ 14 = 20
322 - 280 = 42
42 ÷ 14 = 3
20 + 3 = 23
(If you broke 280 into 140 and 140, you are still correct!)

Add these 4 symbols anywhere between the numbers to make the equation true. You cannot rearrange the numbers.
+ + + -
98 - 76 + 54 + 3 + 21 = 100
I am solving the problem 66 x 44.
Write down two equations with a LARGER product, two equations with a SMALLER product, and two equations with an EQUAL product to the product of 66 x 44.
Then, solve 66 x 44 using the method of your choice.
Answers for larger and smaller will vary.
Answer for equal could include 33 x 88 and 132 x 22
