Class 4 Maths Fractions and Measurement Worksheet with Answers

Equivalent fractions are where the Class 3 idea of equal parts either pays off or collapses. A child who believes 1/3 is bigger than 1/2 because three is bigger than two will not accept that 1/2 and 2/4 are the same amount - so if that comes up here, the fix is a real object cut up rather than more written practice.

Equivalent fractions are where the Class 3 idea of equal parts either pays off or collapses. A child who believes 1/3 is bigger than 1/2 because three is bigger than two will not accept that 1/2 and 2/4 are the same amount - so if that comes up here, the fix is a real object cut up rather than more written practice.

  • Recognise and write equivalent fractions.
  • Compare two fractions with the same denominator or the same numerator.
  • Convert between metres and centimetres, kilograms and grams, litres and millilitres.

Here’s one done for you

1/2 = ___/4. The bottom went from 2 to 4, which is doubling. So the top must double too: 1 becomes 2. Whatever you do to the bottom, do to the top - the fraction stays the same amount because you have cut the same thing into more pieces.

  1. 1)1/2 = ___/4
  2. 2)1/3 = 2/___
  3. 3)2/5 = 4/___

Here’s one done for you

1/2 ___ 1/4 → >. Same top number, so look at the bottom: the MORE pieces you cut a whole into, the SMALLER each piece is. Quarters are smaller than halves, so 1/2 is bigger. This is the rule children find hardest to believe - cut a real roti to prove it.

Here’s one done for you

2/5 of 40: divide by the bottom, multiply by the top. 40 ÷ 5 = 8, then 8 × 2 = 16. Divide first, multiply second - doing it the other way round gives bigger numbers to handle for no reason.

Here’s one done for you

3 m = ___ cm → 300. There are 100 cm in a metre, so multiply by 100. Going the other way (cm to m) you divide. The rule: converting to a smaller unit multiplies, converting to a bigger unit divides - because it takes more small things to make the same amount.

While your child works

  • If your child thinks 1/3 is bigger than 1/2, stop and cut something. A roti into halves and another into thirds, side by side - it takes a minute and it prevents a misconception that otherwise damages every fraction topic through to Class 8.
  • For fraction of a number, divide first and multiply second. Doing it the other way round works but produces unnecessarily large numbers to handle.
  • For conversions, the rule is directional: to a smaller unit multiply, to a bigger unit divide. Children who memorise 'x100' without the direction end up dividing when they should multiply.

The same topic at other levels

Most of these topics are taught over several years rather than in one. If this sheet is too hard or too easy, the same idea at another level is usually the fix.

Questions parents ask

About this worksheet

What are equivalent fractions?

Different fractions that are the same amount - 1/2, 2/4 and 4/8 are all half. The rule is that whatever you do to the bottom number you do to the top, because you are cutting the same whole into more pieces and taking proportionally more of them.

My child thinks 1/3 is bigger than 1/2. How do I fix it?

With a real object, not a worksheet. Cut one roti into halves and another into thirds and put the pieces side by side. More pieces means smaller pieces. This misconception damages every fraction topic through to Class 8 if left, and it takes about a minute to fix physically.

Are answers and worked steps included?

Yes - every exercise has a worked example showing the method, and the word-problem answers show the working rather than just the final number.

Does this Class 4 Maths worksheet come with answers?

Yes. Every exercise has a full answer key, and it prints on its own page at the end rather than beside the questions - so you can hand your child the sheet and keep the answers back. Some exercises also show one question already worked out, with the method rather than just the result, which is the part most answer keys leave out.

Is there a free printable PDF?

Yes, and there is no sign-up, no email and no account. The download button at the top of the sheet gives you the whole thing - all 56 questions across 5 exercises, plus the answer key - laid out to print on A4.

How long does this worksheet take?

About 30 minutes for 56 questions, though that is a guide rather than a target. It is designed to be split: the exercises are ordered so stopping halfway still leaves a complete piece of work, which matters more than finishing at this age.

Can I use it if my child is in a different class?

Often, yes - these topics are taught across several years and schools vary in when they arrive. Judge by the questions rather than the class on the label. If the first exercise is a struggle the level below is the better start, and the same topic at other levels is linked further up this page.
