Adding Fractions Worksheet

2/19/2015

Finally managed to get this one up after I had to correct a few mistakes that we found during the lesson! Adding and subtracting fractions worksheet! Now I am only human so please let me know if you find any mistakes this was a nightmare to put together.. took hours!

This worksheet actually formed the base of my lesson on adding fractions, I used it to break the lesson up into chunks of learning, so we started by looking at the first section and then re-directing to the worksheet. Those that wanted the extra challenge could continue down the worksheet but eventually we all got the the last few sections in the 'could' section.

Now I can't take all the credit for this one as it was created after a lengthy discussion with Mel from www.justmaths.co.uk @Just_Maths so thanks to Mel also for helping me design this :-)

I've made this worksheet so that each line progresses in difficulty. There are very slight changes moving up in the questions showing the progression of this topic. I hope you like it! :-)

Students also have all the answers so there was no need for any hands up! If the answer was't there then it was wrong! (Apart from the one I got wrong that my two 'mistake hunters' found for me)

Using fraction worksheets is very helpful when adding or subtracting fractions. It would help the students to familiarized the correct answer. Let me also share my idea on dealing with fractions.

To add and subtract fractions successfully is to make the rules stick to your memory.

Rules are:
Same denominator:
Add both numerators then reduce. The result would be the final answer.
Different denominator (4 steps):
1. Multiply the numerator of first fraction to the denominator of second fraction. The result is the new numerator of first fraction.
2. Multiply the numerator of the second fraction to the denominator of first fraction. The result is the new numerator of second fraction.
3. Multiply both denominators. The result is the common denominator for two fractions.
4. Add the two new numerators. The result is the answer.

To make it stick to your memory:
Rules for subtraction:
Same denominator:
Subtract second numerator from first then reduce. The result would be the final answer.
Different denominator (4 steps):
1. Multiply the numerator of first fraction to the denominator of second fraction. The result is the new numerator of first fraction.
2. Multiply the numerator of the second fraction to the denominator of first fraction. The result is the new numerator of second fraction.
3. Multiply both denominators. The result is the common denominator for two fractions.
4. Subtract new second numerator from first new numerator. The result is now the answer.

To make it stick to your memory:
Same numerator:
Add two fractions 50 times.
Subtract two fractions 50 times.
Different denominator:
Add two fractions 100 times.
Subtract two fractions 100 times.

To check if your answer is right and your step by step solution is correct:
Use fraction calculator with button from http://www.fractioncalc.com. It is important that you follow the correct steps in adding unlike fraction. Unlike fractions are those fractions with different denominator.

The key here is to make the rules implanted into the minds of the students so that they will never forget.

To solve fraction without a thorough understanding of basic fraction is hard at the beginning. This is so true even in the higher grade levels. Student should understand first how to add, subtract, multiply, and divide fractions. They should have a deep understanding of LCM so that they can decide when to use it or use the butterfly method. They should also have the understanding of equivalent fractions, mixed fraction, and improper fractions. By having a depth understanding, student may find it easy and even fun to deal with fractions.
