Year 5: Monday 30th March – LBQ Fractions Questions Recap

Hello Year 5’s, welcome to Week 2! Last week you completed an LBQ task of 45 questions based on fractions. When looking at your results, there were a series of questions that children struggled with, which they got wrong a few times or skipped. That is fine, this is what learning is all about!

I have hand picked some of these difficult questions again for you to have a look at. I will be writing a steps to success guide for each question for you to read and then use to solve the questions. Please give it your best shot! Lay out each question nicely in your book and label them 1), 2) etc, so you can show all your working out.

1. Success Criteria: The two bar models show a 1/2 and 1/8. Looking at the first bar model, think about your total whole and how many equal parts are shaded in. What is your fraction? Use this information (if your denominators are the same) and add them together. Remember they have only written ‘a half’ because if you simplified your fraction to its most basic form this is what you would get! It is an equivalent fraction!

2. Success Criteria: There are two methods you can use to do this question. Firstly, if you count the whole you will get 6 and notice 15 equal parts are shaded in, giving an improper fraction of 15/6. They have already subtracted for you by taking away the number of equal parts. Use this to figure out how many ‘sixths’ are left.

Secondly, remember you need to make both denominators the same! Find the LCM for both 6 and 3. Then use your common denominator to multiply the fractions so they are equivalent. From here, you will be able to subtract.

Success Criteria: Remember when you are doing sequencing it is simply a number pattern! It is no different from going 2, 4, 6, 8, 10 or 10, 20, 30, 40, 50. The only difference is this is counting in fractions. Also, do not forget 1 whole in this question would be (3/3). Top Tip: Convert them all into improper fractions, this will save you having to count in mixed numbers and you will be able to see the clear pattern! Have a go at converting 2 and 1/3 into a mixed number and use this to identify the next fraction.

Success Criteria: Remember you need to make the denominators the same! This time, rather than making two denominators the same, you need to make three the same because they have given you three fractions! The method does not change. Find the common denominator of 14, 28 and 7. Then use your common denominator to multiply the fractions so they are equivalent. From here, you will be able to subtract.

Do not forget: When you subtract, start with the largest fraction first, otherwise you will end up with a negative! You cannot subtract a larger fraction from a smaller fraction.

Success Criteria: There are two parts to solve this question clearly. Remember break the question down. How you lay it out and present the work is so important. Firstly, I would add just the whole numbers because this makes your life easier! (2+1) and then come back to this later.

After, I would find the LCM for 4, 8 and 16, multiply them to make them equivalent fractions Using this information, I would then add the whole numbers from before and the proper fractions together. Remember a whole number and a proper fraction makes a mixed number!

Success Criteria: Remember you need to make the denominators the same! This time, rather than making two denominators the same, you need to make three the same because they have given you three fractions! The method does not change. Find the common denominator of 4, 8 and 16. Then use your common denominator to multiply the fractions so they are equivalent. From here, you will be able to add your fractions.

Success Criteria for comparing fractions. This time, they have done the hard work for you! They have told you the LCM and common denominator between all of these fractions is 8. Use this information to convert all of these fractions into equivalent fractions of 8. Once they are all the same, see if you can order them in ascending order, then descending order.

  5. Mohammed I.

    I have done it in my homework book.

  6. Lakeysha M.

    I did this on my homework book. I found this easy.

  7. Zavian K.

    what shall I do because I don’t have my homework book

  8. Rifath A.

    1) 1/2 + 1/8 = 5/8

    2) 15/6 – 8/6= 7/6=1 whole and 1/6

    3) 1/3 , 1 whole , 5/3 , 2 wholes 1/3 , 3 wholes

    4) I think it’s 5/27

    5) 3 wholes and 15/16

    6) = 63/16= 3 wholes and 15/16

    7) 5/8 = 5/8 , 3/4= 6/8 , 1/4 = 2/8 , 1/2=4/8
