What’s the perimeter?

Posted by on October 17, 2016

We’ve had the metre sticks and rulers out in Year 3 this week.  We have been measuring the perimeter of large shapes in the hall and small shapes in the classroom.  Have a go at these questions at home.

 

Challenge: Can you write the instructions of how to work out the perimeter of a shape?

    4cm + 4cm + 2cm + 2cm = 12 cm 3cm + 3cm + 3cm + 3cm = 12 cm 4cm + 4cm + 3cm + 3cm = 14cm 6cm + 6cm + 2cm+ 2cm = 16cm

      Well done for realising you had forgotten to write cm and correcting your answers.

    you work your perimter by measiring all sides and then adding them up and you get the perimter because thats the total
