You can also represent these types of problems with cubes or money manipulatives if you need a concrete example. Since the story said Brent has 3 time more, draw 3 bars equal to the size of Joe’s bars. Since Joe’s bar is and the bars by Brent’s name are equal in size, all of Brent’s bars should be labeled with . To find out how much Brent has, solve by repeated addition or multiplication. IF the question was slightly different (How much do Joe and Brent have all together?), then the above steps would have to be followed by 1 more step (adding the two amounts together).
If you have seen my fraction posts, I teach children to divide the bar in half, then divide each half in half to get four equal parts. Aliyah’s amount is equal to the size of of the Shayla’s sections (one fourth). Solve by thinking of this: 4 of the same amount = 28. So he/she is closer now, and most likely would try 6 or 7 next.
This method allows a child to even do it by trial and error if they don’t know their facts well yet.
Like with addition / subtraction comparison problems, I will show some ways to use double bars to illustrate these. pdf showing the pictures of the problems shown below – get it now Equal groups comparison problem pics) Notice some of the questions associated with these stories.
They sound a lot like questions used in other story structures — this is why I advise statements like, “If it asks how many in all, add the numbers together.” Notice how this method guides a student as they go from pictorial to abstract.
We use division or multiplication when the problem involves equal parts of a whole.
The following diagram shows how to use division to find unknown size of parts or groups or to find unknown number of parts or groups. How to solve multiplication and division problems by drawing a diagram?
Example 1: If it takes 5/6 yards of fabric to make a dress, then how many yards will it take to make 8 dresses?
Analysis: To solve this problem, we will convert the whole number to an improper fraction. Solution: Answer: It will take 6 and 2/3 yards of fabric to make 8 dresses.
But first we must convert each mixed number to an improper fraction.
Solution: Answer: The area of the classroom is 9 and 7/20 square meters. If it is divided into pieces that are 3/8 of an inch long, then how many pieces is that?
