I have returned the following today for your parent's signature:

1) EDP WS : Chapter 15 Time WS 2
2) EDP WS : Chapter 13 Area & Perimeter WS 1 and WS 2

For finding perimeter of a composite figure, do use the highlighting method for finding sides of same length .

This helps you to add up less sets of numbers and hence reduce the possibility of calculation errors.

 Adding up all the sides of a composite figure to find perimeter.

 

Adding up all the 8 sides separately  may cause calculation errors . 

 Examples of highlighting method: 

Using highlighting method , we only need to add 4 sets of numbers to find teh perimeter compared to 8 sets of numbers. 

Using highlighting method, we added up 4 sets of numbers to find the perimeter compared to adding 8 sets of numbers . 

Another example: We added up 6 sets of numbers ( 2 greens sides, 2 yellow sides and 2 purple sides ) instead of adding up 8 sides.
