Chapter 11.1 (Mathematics 5)

Millilitre

Millilitre as a unit of measuring capacity

Group Activity 1

In groups of five:

  1. Get a transparent straw and close one end.
  2. Fill a spoon with water.
  3. Put the water into the straw.
  4. Mark the height of the water in the straw.
  5. Divide the height of the water in the straw into five equal parts.
  6. If the spoon holds 5 millilitres of water, discuss:
    1. the amount of water in the straw.
    2. the amount of water in one of the five equal parts of the straw.
  7. Discuss and share the results with other groups.

Note

The millilitre is a small unit of measuring capacity.

Millilitre in short is written as ‘ml’.

Measuring capacity in millilitres

Group Activity 2

In group of four:

  1. Fill a 5 ml spoon with water and pour the water into a small transparent bottle.
  2. Mark the level of the water and write 5 ml.
  3. Continue pouring one spoonful of water into the bottle and labelling after every one spoonful as shown.
  1. Repeat the activity using a cylinder marked in millilitres.
  2. Use the marked bottle to measure capacity of other small containers.
  3. Discuss your results and share with other groups.
  1. A small bottle  ml
  2. A glass  ml
  1. A bottle  ml
  2. A cup  ml

Group Activity 3

In groups of five:

  1. Get three small containers of different sizes and shapes.
  2. Label the containers 1, 2 and 3 using a pen or a pencil.
  3. Estimate and record the capacity of each container. Measure the capacity of each container. Record your results in the table shown.
