Alternative: To convert mL into L, just write the last 3 digits as mL and the remaining
digit or digits as L.

As, 9950 mL = 9 L 950 mL

Project Experiential Learning

Find out how much water your family uses each day. You can begin by
checking one activity, like bathing.

♦ Take your bathing mug and find its capacity in L and mL.
♦ How much water do you use while bathing?

♦ Who in your family uses the most water for bathing?
♦ Who uses the least amount of water for bathing?

♦ Compare their water usage and write down the difference.

1. Fill in the blanks with the most suitable unit (mL or L) to measure the capacity of
the following.

(a) Water in your water bottle = 500 ___ (b) Tea in a cup = 200 ____
(c) 3 pouches of milk = 3 ____ (d) Pulses in a pressure cooker = 2 ____

(e) Lemon soda in a glass = 300 ____ (f) Sanitizer in a bottle = 50 ____

2. Convert litres into millilitres.

(a) 2 L (b) 5 L (c) 7 L (d) 9 L

Teacher’s Use real-life examples to discuss how when we change a bigger unit into a smaller unit, we multiply; and when
Tip we change a smaller unit into a bigger unit, we divide.
