INTRODUCTION TO CAPACITY MEASURES
The quantity of liquid a container can hold is known as capacity of the container. For example the amount of water a keg or gallon can hold is the capacity of the keg.

CONVERSION OF UNITS OF CAPACITY
There are various units for measuring the capacity or volume of liquid. The basic ones are the liters (l) and the Milliliter (ml).
Great capacities are measured in liters while small capacities are measure in cubic centimeter (cm³) or milliliters
TABLE OF CAPACITY MEASURES
10 milliliters (ml) = 1 centiliter (cl)
10 cl = 1 deciliter (dl)
10 dl = 1 liter (l)
1000 ml = 1 liter
100 cl = 1 liter
1000 l = 1 kiloliter (kl)

STARTER
Begin the lesson by showing the pupils various containers and asking them which one will hold more liquid.

PLENARY
Pupils should be able to define capacity and know various units of measuring capacity.

EXERCISE
Group work : share them into two groups and give each a 50cl bottle and ask them number of 50cl bottles that will fill one and half litre bottle.

Seat work: convert 1000l, 2500l, 350l to cl, ml and kl repectively.
Convert the following to litre
i. 950ml
ii. 100cl
iii.10ml
iv. 2000ml
v. 500cl

Tuesday
Perform Arithmetic operation of adding capacity unit.

Addition of capacity is similar to the basic addition problems, but when carrying the extra you should remember that:
10ml = 1cl
100cl = 1l
1000ml = 1l
Examples
1. 2cl 6ml + 4cl 15ml
Solution
cl          ml
2          6
+    4          15
7            1

2. Add 2l 35cl 3ml to 3l 75cl 8ml
Solution
l           cl             ml
2          35            3
+   3           75           8
6            11          1

STARTER
Start the lesson by asking them questions on units of capacity and perform basic addition operation.

PLENARY
Pupils should be able  to add various units of capacity together.

SUBTRACTION OF CAPACITY MEASURES
Subtraction of capacity is similar to the basic subtraction problems, but when borrowing you should remember that:
10ml = 1cl
100cl = 1l
1000ml = 1l
EXAMPLES
1. 4cl 2ml - 2cl 7ml
Solution
cl           ml
4            2
-      2             7
1            5

2. Subtract 7ml 58cl 9ml from 9l 48cl 5ml
Solution
l            cl            ml
9            48           5
-       7            58          9
1            89          6

STARTER
Begin the lesson by doing the first example for them.

PLENARY
Pupils should be able  to subtract various units of capacity.

MULTIPLICATION OF CAPACITY MEASURES

EXAMPLE
1. 6l 27cl 4ml × 6
Solution
l              cl               ml
6             27               4
×                                 6
37            64                 4

DIVISION OF CAPACITY MEASURE
EXAMPLE

2. 9l 70cl 4ml ÷ 4

Solution
l               cl              ml
4 | 9              70              4
2              42             6

STARTER
Begin the lesson by doing the first example for them.

PLENARY
Pupils should be able to multiply and divide various units of capacity.
