Division Word Problems

This week we worked on creating and solving division word problems. Mrs. Griswold started with a great problem for us to solve!

Mrs. Griswold went to the store and bought a package of 20 Harry Potter silly bandz for her 12 students. How many silly bandz would each student receive?

After the students easily solved this problem and discovered that each student would get 1 silly band with a remainder of 8, she posed another problem to the class:

Mrs. Griswold doesn't want to have any remainders after giving her students the silly bandz. How many packages would Mrs. Griswold need to buy, with there being 20 in a package, so that each student received the same amount without having any leftovers? How many silly bandz would each student receive?

The students collaborated to find out that Mrs. Griswold would need to buy 3 packages, which would equal 60 silly bandz. Each student would receive 5 silly bandz and there would be no remainders. Even more exciting than solving the puzzle, was when they found out that they were really going to receive 5 silly bandz each!!

After solving the problems, the students had to explain how the solved it. Then each student, or pair of students, created a division word problem and wrote the explanation of how to solve it!



Ian
Word Problem: Ian bought a container of legos for his class. It had 500 pieces and there were 8 people in his class including him. How many containers would Ian have to buy for everyone to have the same amount. 
Step-by-step explanation of how to solve the problem:
1.) Start with 100 divide among 8 people. Each person should get 12 legos with a remainder of 4.
2.) Then multiply 12 x 5 and you should have 60 legos for each person. Then the remainder should be 20.
3.) Divide the reminder up and each person should get two more legos. Then it should be 62.
