Year 3 Measure perimeter worksheets with answers

Measure the sides of shapes with a ruler and add them to find the perimeter. A free editable Word sheet with eight fluency and six reasoning questions. The answers follow the questions: the same sheet again with every answer in red.

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.

    Is Mia correct? Circle yes or no.
    Circle yes or no.

    No; No. 12 × 4 = 48 is the area, not the perimeter. The perimeter is 12 + 4 + 12 + 4 = 32 cm.

  4. Rectangles have sides that are whole numbers of centimetres. A 2 cm by 5 cm rectangle is the same as a 5 cm by 2 cm rectangle.
    How many different rectangles have a perimeter of 14 cm?

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.
