Division

Miss Lewis is headed to HEB to buy Coco some dog food Miss Lewis is headed to HEB to buy Coco some dog food. Coco eats 3 cups of dog food per day. The label explains that there are 27 cups in the bag. How long will a bag of dog food last Coco? Work with your table group to help solve Miss Lewis’s problem.

How would you solve this? Will Coco eat the whole bag or about the whole bag? Will there be any food remaining in the bag? Could you solve this a different way?

How many groups of 3 will it take to fill up the red strip? Miss Lewis is headed to HEB to buy Coco some dog food. Coco eats 3 cups of dog food per day. The label explains that there are 27 cups in the bag. How long will a bag of dog food last Coco? 27 cups of dog food 3 cups How many groups of 3 will it take to fill up the red strip?

Mathematicians show this as an “equation”……a math sentence 27 cups of dog food 3 cups Mathematicians show this as an “equation”……a math sentence whole ÷ part = part dividend ÷ divisor= quotient

dividend ÷ divisor= quotient 27 ÷ 3= d d=9 27 cups of dog food 3 cups whole ÷ part = part dividend ÷ divisor= quotient 27 ÷ 3= d d=9 Mathematicians show division 3 different ways: 27 ÷ 3= 9 9 27 3 =9

Practice Problems: Draw a strip diagram for each problem Practice Problems: Draw a strip diagram for each problem. Then, write an equation to justify your strip diagram. Lastly, solve your problem. Blake has 28 marbles. He puts them into 4 bags. He puts the same number of marbles in each bag. How many marbles are in each bag? Wendy has 36 books. She has a bookshelf with 6 shelves on it. If Wendy puts the same number of books on each shelf, how will be on each shelf? Jesse has 45 toys and 5 boxes. If he puts the same number of toys in each box, how many toys will be in each box?

The next month Miss Lewis found a bag that had a capacity of 225 cups The next month Miss Lewis found a bag that had a capacity of 225 cups. If Coco still consumes 3 cups per day, how many days will the bag last? Discuss with your group how you could solve this problem?
