 Know a decimal number
 Define decimal as a fraction whose denominator is 10 or a power of 10.
 as an alternative way of writing a fraction.
Information for Teachers
 A decimal number is a number that has a decimal point somewhere in number could look like these: show fraction with a dot (ֺ▪)
 Ashraf`s house is 3.429 km from school. The parts of this distance can be shown like this: as;
 We can say that Ashraf’s house is 3.429 meters from school. We can also say that Ashraf’s house is 3 km and 429 meters from school.
 The best way to write the distance is 3.429 km away. This means we are using decimals and have to understand what the decimal parts mean, as;
0.8 In table form
1.123 In table form
3.429 In table form
0.124 In table form
666.666 In table form
1234.224 In table form
Material / Resources
Writing board, chalk/marker, duster, mud balls one per group (playing dough / plasticize can also be used in place of mud balls if available, graph paper, textbook
Introduction
 Ask the students:
 Have you seen the electricity bill, petrol prices, telephone bill or mobile bill “free sms bundle offer!”
 Ask the students to describe places where they have seen decimals. List their responses on the board.
 Ask somebody to define factors, collect responses on board. Now conclude the discussion on “parts of whole”.
 Announce that today we are going to look at fractions in another way that is called: Decimals” [parts of a whole].
Development
Activity 1
Group Work:
0.04 (Red) 0.06(Green) 0.08 (Blue) 0.12 (pink)

Activity 2
:Fraction are also represented by decimals, as; 
Activity 3 Teachers in put (Continue to explain)

Activity 4 Working in Pairs:

Sum up / Conclusion
 A decimal number is a number that has a decimal point, as; 3.592.
 Decimals are another way of showing fractions
 Decimal numbers when converted into fractions then in the denominator always 10, 100, 1000, come according to the number of digits after the decimal.
Assessment
 If I have three boxes full of pencils (10 in each) and another half, what would be fraction (let them answer) 3 and half, in decimals what will we call 3.5 (half of 10 is 5)
 Ask students to give one similar example.
 Have 5 o 10 examples from the whole group.
 Plot fractions on number line, they learnt before, help them visualize decimals on number line.
 Let`s do decimal counting:
 With the teacher whole class read counting aloud.
 The whole class does it together, 1, .1, 1.2, 1.3. 1.9, 2.0, 2.1, 2.9, 3.0
 Change the following decimal numbers into fractions.
 Fill in the box with suitable number.
Follow up
 Note the unit cost of electricity bill at home.
 Ask the per liter cost of petrol (parents)
 Change the following fractions and mixed numbers into decimals.
