Presentation transcript:

Interpreting Division I can decide whether a division question is asking “how many groups?” or “how many in each group?”. I can create a diagram or write an equation that represents division and multiplication questions.

Draw a diagram and write a multiplication equation to represent each of the following situations. Then answer the question. Mai had 4 jars. In each jar, she put 2 1 2 cups of homemade blueberry jam. Altogether, how many cups of jam are in the jars? Priya filled 5 jars, using a total of 7 1 2 cups of strawberry jam. How many cups of jam are in each jar? Han had some jars. He put 3 4 cup of grape jam in each jar, using a total of 6 3 4 cups. How many jars did he fill?

To make 1 batch of granola, Kiran needs 26 ounces of oats To make 1 batch of granola, Kiran needs 26 ounces of oats. The only measuring tool he has is a 4-ounce scoop. How many scoops will it take to measure 26 ounces of oats? Will the answer be more than 1 or less than 1? Write a multiplication equation and a division equation that represent this situation. Use “?” to represent the unknown quantity. Find the unknown quantity. If you get stuck, draw a diagram.

The recipe calls for 14 ounces of mixed nuts The recipe calls for 14 ounces of mixed nuts. To get that amount, Kiran uses 4 bags of mixed nuts. Write a mathematical question that might be asked about this situation. What might the equation 14÷4=? represent in Kiran’s situation? Find the quotient. Show your reasoning. If you get stuck, draw a diagram.

I can use diagrams and multiplication and division equations to represent “how many groups?” questions. I can find how many groups there are when the amount in each group is not a whole number.

Write a multiplication equation and a division equation for each statement or diagram. Eight $5 bills are worth $40. There are 9 thirds in 3 ones.

For each situation, draw a diagram for the relationship of the quantities to help you answer the question. Then write a multiplication equation or a division equation for the relationship. Be prepared to share your reasoning. The distance around a park is 32 miles. Noah rode his bicycle around the park for a total of 3 miles. How many times around the park did he ride? You need 34 yard of ribbon for one gift box. You have 3 yards of ribbon. How many gift boxes do you have ribbon for? The water hose fills a bucket at 13 gallon per minute. How many minutes does it take to fill a 2-gallon bucket?
