Year 3 Equivalent capacities and volumes (litres and millilitres) worksheets with answers

Download the worksheets

Printing tip: the red answers are in the same file, after the questions. For pupils, print only the pages before the red answers (in Word, choose the pages in the print box). Keep the full file for marking.

Print on A4 portrait: every page carries the sheet twice, side by side, so you can cut down the middle and two pupils each get a half to stick in their books. Every question sits in its own box and pupils write their answers in their book. The answers follow the questions in the file: the same sheet again with every answer in red. It opens in Word, Google Docs, Pages and LibreOffice, so you can change numbers, delete questions or add your own. There is no scaffolded version of this step yet.

Not scaffolded sheet

The same questions without the extra support. For pupils working at the expected standard: eight fluency questions first, then the reasoning questions.

Sample questions from this step

These are real questions from the first set of the sheet (two from the fluency page, two from the reasoning page). Open each one to see the answer.

  2. Complete the statements.
    a) 1,050 ml = ____ l ____ ml

    Is Boba correct? Circle yes or no.
    Circle yes or no.
    Explain how you know.
    Show the answer

    No; There are 1,000 millilitres in 1 litre, so 3 l = 3,000 ml, not 30 ml.

  4. Write <, > or = in each box.
    a) 2 l 50 ml ____ 2,500 ml
    b) 3,000 ml ____ 3 l
    c) 1 l 500 ml ____ 1,050 ml

    <; =; >

What is on each sheet

  • Fluency: eight questions that start easy and get harder, with the key skill of the step practised in different ways.
  • Reasoning: questions with pictures, tables and number lines (spot the mistake, true or false and explain, puzzles with one answer, an open-ended task).
  • Answers in the same file: the sheet again with every answer in red, so there is only one file to download.
  • Boba characters give the instructions in speech bubbles. They are decoration only.
