Pupils respond and participate

STEP 2

CONCEPT

DEVELOPMENT

The teacher

 • Shows the learners the bathroom scale that you have brought from home.

What types of mass you can measure using a bathroom scale. Remember to explain the mathematical

terminology to the class and make sure that they know this terminology well.

• Lets the learners look around the class and see what items they could find the mass of using the bathroom scale, e.g. a heavy school suit bag, a pile of maths books. (Items must be able to balance on the scale and not cover the mass meter.)

• Discusses which items one could not find the mass of using the bathroom scale.

• Asks: Why not? (e.g. Light items, such as a book, since the bathroom scale measures in kilograms.)

CLASS ACTIVITY

The teacher

• Place a range of products that have a mass of 1 kg, 2 kg or 3 kg and some products that have a mass

measured in grams on a table in front of the class. For example:

• Holds up a 1 kg product and a product with a mass of less than 1 kg, e.g. 1 kg Skip and 500 g Omo.

• Shows and reads the mass to the class. Ask Which is lighter – 500 g Omo or 1 kg Skip? Invite a few learners to hold the items and feel the mass.

• Asks Why is the 500 g lighter than the 1 kg? (Even though the number 500 is a bigger number than 1, grams are much smaller than kilograms. 1 000 grams make 1 kg. Therefore 500 g is less than 1 000 g which is the same as 1 kg.)

• Does the same with various other options and combinations, e.g. Provita and Red Label biscuits.

• Asks learners to come up with suggestions of items which can provide a combined mass of 1/2/3 kg. They may use single or multiple items, e.g. 8 packets of Provita have the same mass as a 2 kg packet of Skip.

• Gives learners a selection of products, e.g. Red Label, Iwisa, Ace and Provita. Ask learners to place these in order from lightest to heaviest.

• Does the same with other products also ordering them from heaviest to lightest.

Pupils pay attention and participate

STEP 3

CLASS-WORK

1. Which is the heaviest product above?

2. Which is the lightest product above?

3. Name 2 items that have a combined mass of less than 1 kg.

4. Name 2 items that have a combined mass of 500 g.

Pupils attempt their class work

STEP 4

HOME-WORK

1. Use a bathroom scale to find your mass.

2. Sort these soaps in order of mass from lightest to heaviest.

STEP 5

SUMMARY

The teacher summarizes by reminding the pupils how to Compare, order and record the mass of commercially packaged objects which have their mass stated in

kilograms.

She marks their class works, makes corrections where necessary and commends them positively

CONCEPT

DEVELOPMENT

The teacher

 • Give each group of learners pictures of products on which they can see the capacity, e.g.

• Asks the learners to order the containers from the one that holds the least to the one that holds the most.

CLASS ACTIVITY

The teacher

• Discusses comparisons between pairs of containers (based on pictures that you have brought to class).

For example:

− The capacity of the Sunlight Liquid container is ______. (5 litres)

− The capacity of the milk container is _____. (1 litre)

− The capacity of the Vanish container is ______. (1 litre)
