Here is the worksheet that I found on education.com. I completed the first 7 problems on the worksheet. I completed this at a 4th grade level.
https://www.education.com/worksheet/article/fraction-math-addition-subtraction-2/ is the link for the worksheet.
This was a lot more difficult then I thought! I forgot what it was like to simplify fractions. I think that is where my biggest struggle was. But after doing this I can say that I am getting better at finding the common divisor, and dividing both numbers by it, and arriving at a simplified final answer.
Here is my work:
1. 2/3 – 1/3 =1/3
First I had to subtract 2-1/3 and that is how I came to my
final answer of 1/3
2.
6/12 + 5/12= 11/12
I had to add 6+5 =11/12 and that is the
simplified answer as 1 is the greatest common divisor of 11 and 12.3. 7/16 – 3/16=1/4
First I had to subtract 7-3/16=4/16. Then I had to simplify
4/16 into it’s lowest terms.
( 4 ÷ 4 ) over ( 16 ÷ 4 ) =1/4
Final answer. I arrived at this answer as you can see by diving 4 and 16 by
it’s common divisor of 4.
4.
8/10 – 2/10= 3/5
First I had to subtract 8-2/10= 6/10
Then 6 ÷ 2 and 10 ÷ 2 = 3/5. 2 was the common divisor.
5.
7/8 + 3/8= 1 ¼
First I had to add 7+3/8=10/8
Then simplify 108 = ( 10 ÷ 2 ) and ( 8 ÷ 2 )
=5/4
Then I had to convert an improper fraction to a mixed
number.
5 ÷ 4 = 1 remainder 1 = 1 ¼
6.
6/9 – 6/9 =0/9
First subtract 6-6/9=0/9 so final answer is 0.
7.
4/16 + 4/16=1/2
First add 4+4/16=8/16
Then simplify and 8 is the common divisor of both so 8 ÷ 8 16 ÷ 8
=
1/2
What a great first step reviewing fractions. Describing anyone’s mathematical thought process can be tricky, but you did a wonderful job. I urge you to use parentheses (e.g., (7+3)/8=10/8=1 1/4) to help denote the addition of numerators, but your written expanlations were precise and detailed. What might be your next exploration with fractions? What about other operations? -Dr. Moldavan
ReplyDeleteThanks. It was difficult because I was on my laptop and I didn't have access to a scanner, so I had to type or write out everything. This week I am dividing fractions and have access to a scanner to show the work.
DeleteHi, Kassandra J, it's great how you explained everything so simple and understandable, it looks easy to do, thanks! As soon as I got how to simplify the numbers, (kind of reducing numbers) it begun easy to find the right answer. Thank you!
ReplyDeleteThank you Kassandra for this step into fractions! Fractions can be such struggle. I was reviewing them as well for my PLP in hopes of being able to more effectively process and pose ways to engage students to not be intimidated by them as I have been. I like your approach to just bringing the reality of and measurable proof for: practice may not make it perfect, but it can make it more permanent! Thank you!
ReplyDeleteNice feedback everyone.
