Stretch Worksheet on Area & Perimeter

Hi 4A,

This post is for Question 1 of our Area & Perimeter Stretch Worksheet.

Method 1 solution :

To visualise by removing  the concrete path and rejoining the remaining park.

Hence the length became : 30m - 3m = 27m

Area  covered by grass =  Length x Breadth
                                      =   30 m x 27 m
                                        = 540 square metres 

Some of you came up with the alternative solution of finding the area of the concrete path.

Method 2 solution: 

 Area of concrete path = 3 x 20 = 60 square metres
Area of Park = 30 x 20 = 600 square metres
Area covered by grass = 600 - 60 = 540 square metres

For this solution , we need to find the area of 2 parallelograms first ( which is also Length x breadth)

Watch this video to help you visualise.

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.

Ordering of Fractions - Best Practices

Best practices for ordering of fractions.

Step 1 : Converted to equivalent fractions of the same denominator

Step 2 : Label "greatest, middle and smallest' by their sides.

Step 3 : Circle the original fractions as given in teh questions.

Step 4 : Transfer the fractions into your  answer space in increasing or decreasing order as required    
              by the question.

Step 3 is important to remind yourself to express your final answer following the fractions given in the questions and NOT the equivalent fraction you have converted.  Many of you made the mistake of writing your final answers as the converted fractions.

Decimals

Here are some photos of our class learning decimals.

Getting them familiar with the place value of decimals.
