Grade 9 Mathematics (Measurement)

The purpose of the following assessment is to test your knowledge based on measurement in the subject Mathematics.

Measurement is a very important part of the subject mathematics. It is something we make use of in real life situations and our everyday lives.

What is Measurement?

It is a number that shows the size or amount of something in real life situations. Usually the number is in reference to some standard  measurement, such as meters, kilograms, gram, litres, etc

Why is measurement important?

This part of mathematics is important, because it helps us to quantify the world around us.

An understanding of the processes of measurement, the concept of a unit , and a familiarity with the tools and common units of measurement, are all critical for you as learners to develop an understanding of the world around yourselves.

NB: Students are required to work individually 

Have fun !

Question 1

The following picture is an example of a rectangular prism

Find the:

a) Volume of this rectangular prism based on the following measurements                                                                                     (4)

Question 2

Caster Semenya is an athlete that specialises in the 800m middle distance race 

She wants to improve her personal bests and that is why she decided to train with the best middle distance on this globe in Kenya. On her way there she must go visit her aunt in Windhoek, the capital city of Namibia first before she leaves for Kenya.

h) After their warm up session they do a speed session that consists of 5x 200m and 5x 400m.

    When they completed that they do another warm down jog for about 1,5km.

    Calculate the total amount of distance they cover for one day                                                                                                    (3)

i) Calculate The total amount of distance they cover for the week. Convert your final answer to miles                                          (3)

b) She needs 750 ml of milk, but the object she measures with only states the measurements for gallons. 

    Convert 750ml to gallons                                                                                                                                                             (4)

Step 1

Please note that this assessment counts 50% of your term 2 mark, due to the Covid-19 pandemic

Try to complete the test individual without the help of others. 

The the link to submit this assessment will be available from 12pm- 2pm

Complete all answers.

Step 2

Go through your previous notes that was given based on the topic measurement

Important content to remember:

• Gallon - Litre
• Kilometres - Miles
• Kg - Lbs
• Meters - Feet 
• What is measurement?
• Why do we make use of measurement?
• How can we relate to it in our everyday lives?

Formulas you can make use of:

• = (amount of days x distance) 
• A = Length x breadth
• V = Length x Breadth x Height 
• formula / (1'c x 9/5) + 32
• P = (Length x 2) + (breadth x2)
• = formula/ 1 millilitre = 0,000264172
• = (Cape Town to Windhoek) + (Windhoek to Nairobi)

Step 3

NB: Submit this assessment on google classroom when you are done

Rubric

'Not all of us has mathematics as a favourite subject. 

This activity was to test your knowledge on how good  you understand the topic measurement.

Not everyone is always up for individual work, but this is to show that we need to try stuff on our own as well without the help of others. This way helps you to learn and be  responsible.

Discovering what your strongest ability is and using it to it's full potential will have a great outcome on anything you will do.

Ask yourself what you have learn and how you will apply these knowledge in real life?

A quote of motivation to my learners:

" You have brains in your head and a calculator in your hands. So why not combine the two and solve whatever you have to do :)"

                                                                                                 - Mr Kannemeyer

My name is Reinholdt Kannemeyer. 

I have always had a battle of choosing a specific career choice. My love for teaching stared when a few learners with me in school or evens in the younger grades always asked me for help, to help them solve their Mathematics problems. I am currently a final year student at the Cape Peninsula University of Technology. My major subjects is Mathematics and Afrikaans. I am planning on continuing my studies at the University of Cape Town the following year to focus more on Mathematical content wile doing my Honours Degree. As a 22 year old, I have seen the importance of Mathematics in Education and how it comes handy in our everyday lives.

I think that we are supposed to be there for each other in the Educational field. We all learn from one another this way. I give permission to who ever wants to use this WebQuest in the teaching and learning environment to use it if it will be beneficial to him/her as long as the person that is using it gives me credit for my work and ideas.

I created this WebQuest to see how good you understand this topic in mathematics.

I also made use of this since it can be very much relatable to real life content and situations
