Lesson Planning of Conversion of Units of Capacity
Subject Mathematics
Grade 4^{th}
Students` Learning Outcomes
 Convert liter into millilitres and vice versa.
Information for Teachers
 Capacity can be measured by using millilitres and liter.
 Liter is denoted as L and millilitre as ml.
 The liter was introduced in France in 1795 as “unit of measurement” which is derived from a French unit ‘litron’.
 One liter of liquid water has a mass of almost exactly one kilogram.
 Mill means 1000^{th} part which is used for measuring small quantities.
 1 liter = 1000 millilitres.
 Liters can be converted into millilitres by multiplying liters with 1000, so, ml = L x 1000.
 Milliners can be converted into liters by dividing millilitre with 1000 so, L = ml/1000.
 During this lesson the teacher should consult with textbook at each level wherein and whenever it is required.
Material / Resources
Writing board, chalk/marker, duster, plastic bottles of different sizes, a medicine dropper, water glass, syringe, a cup of tea, syrup, note book and textbook
Introduction
 Ask the students: have you ever noticed how much water your bottle contains?
 Show them label of the bottle that it can hold 1 liter or 1000 millilitre of water in it.
 A cup of tea can hold about 500 ml of tea.
 A glass of water can hold about 250 ml of water in it.
Development
Activity 1 Conversion from Liter to Millilitre:

Activity 2 Conversion from Millilitre to Liter:

Sum up / Conclusion
 Repeat the key points that you discussed during this lesson.
 Capacity can be measured in liter and millilitres.
 Liter is used to measure capacity of large whereas millilitre to measure small products.
 Mill means 1000^{th} part.
 Liters can be converted into millilitres by multiplying liters with 1000 so, ml = L x 1000 ml.
 Millilitres can be converted into liters by dividing millilitre with 1000 so, L = ml /1000.
 Satisfy the students if still someone have problem in understanding the concept.
Assessment
 Convert the following capacities in the given capacities: as;
 18. 3 L = ________ml,
 215 ml = ________L,
 29 L = ________ml,
 33.3 L = ________ml,
 55 ml = ________L
Follow up
 Assign homework to further strengthen their concepts, as;
 Three students gifted three bottles of juice to their teachers of 1.5 litters, 1 litter and 500 ml. calculate the total quantity and convert the total juice in ml.
