P6 Numeracy 11th February

Perimeter Lesson 1

Let's revise our P4 and P5 learning as we practise measuring the distance around the outside of a shape.

Warm-up activity

Let's begin by practising adding and subtracting decimals! 

Download the "Division addition and subtraction warm-up" and do your best to complete each calculation.  If you're writing out the questions on a page, remember to keep your decimal points in a straight line and don't forget to place a decimal point in each answer please.

Main activity

Last week we were learning about area.  Area measures the amount of surface covered by a shape.


Today we are going to revise perimeter. Perimeter measures the distance around the outside of a shape.


Watch today's video where Mrs Bell reminds us how to find the perimeter of a rectangle or square and then have a go at today's written activities.

Extension task

Download the "Squared page template".  Using a ruler, can you draw three different rectangles which each have a perimeter of 30cm? Remember, (length + breadth) X 2 = perimeter.


Once you've drawn your three rectangles, calculate the area of each rectangle.  Remember, area = length X breadth.  Do all three rectangles have the same area or are they different?

Reasoning task
