A B UNIT Lesson Plan Fractions and Place value and conversion of decimals to fractions T: Can you remember the place value table? Can you tell me the headings we use? Ps:... hundreds, tens, units, tenths, hundredths, thousandths,... T: Right. Now, I'll say some decimals, and you have to write them on the table. Then someone can volunteer to put them in order, smallest first. T says, volunteer Ps write into table: 9 thousandths tenths hundredths Hundreds Tens Units tenths hundredths thousandths 0 0 0 0 0 9 0 0 0 0 0 0 0 0 0 0 P: 0. 009 < 0. 0 < 0. Converting fractions to decimals T: What other way can you write tenths? (As a fraction) T: So, can you write it in this form? P (writes on BB): 9 T: And the other two numbers? (, ) 0 T: How do we write these numbers as decimals? (0., 0.009, 0.0) T: Can you think of yet another way to say tenths? (e.g. 00 thousandths, since T: And what about (T writes on BB): 0. Ps dictate, T writes on BB: 0 tenths hundredths = + = + = = hundredths T: Let's do the same with 0.06. Ps dictate, T writes on BB: 00 = ) 0 6 00 6 tenths 6 thousandths = + = + 0 0 0 = 06 0 Conversion of Decimals and Fractions T makes Ps recall their knowledge of decimals, and find the connection with fractions. T sketches a table on BB; Ps say the numbers aloud and volunteer Ps write them on the table. Another volunteer P writes these numbers on BB in order of size. Ps write in Ex.Bs. Agreement. T and Ps revisit the concept of improper fractions and mixed numbers. T: If the decimal is larger than, will that give us any problems? Ps dictate, T writes on BB: units tenths = 0 = + = = tenths mins
UNIT Fractions and Lesson Plan Practice converting decimals to fractions T: Did you realise how easy it was to convert decimals to fractions? Now you can try some for yourselves, like this: Someone comes to the front and writes a decimal on BB. They call another person to read it out and write it as a fraction. Then this person will write a decimal on the BB, call another person, and so on. Are you ready? Let's start with decimals smaller than. Who'd like to write the first one? e.g. P writes on BB: 0. and chooses P. P (says): hundredths (writes):, etc. Converting fractions to decimals Can you do this in reverse? We'll see. OS., Q Q Q8 Q Q Q Q6 Q T: But what about 9 69 0 6 0 0 = 09. = 0. 69 = 6. = 00. = 0. 00 = 0. = 0. 0 =. 0 mins? We'll look at this one later. 0 8 mins Decimals to fractions OS. T: Look at question. Why do you think the second equals sign and fraction line are there? (Because the fractions can be written in several forms) T: For example? ( 8 = 80 6 = 800 0 = = 0, etc.) T: Why is it that a fraction can be written in several forms? (Because its value stays the same if we multiply or divide both its numerator and denominator by the same non-zero number) Conversion of Decimals and Fractions P who wrote the number on BB decides if answer is correct, T and other Ps agree or not. Correct solution is written in Ex.Bs. After about decimals have been converted, T asks Ps to now choose decimals larger than. When all Ps have had a turn, T ends the activity. Praises Ps. Brief whole class activity; Ps should find this straightforward after the previous work. Problems appear on OHP. For the first few fractions, volunteer Ps come to front, explain and write solutions on OS; other Ps write in Ex.Bs. The remaining problems are worked on individually in Ex.Bs, monitored, helped. Checking at OHP; T points to P, P answers. Agreement, feedback, T writes solution on OS self-correction. T encourages more and more Ps to give examples, writes them. on BB, then makes Ps recall the rule using correct mathematical language.
T: Which form do you prefer to work with? UNIT Lesson Plan Fractions and T: Why aren't we given another fraction line in question? ( 00. =, and this is its simplest form) T: Right. Now, write the other decimals as fractions and find their simplest forms.

P answers in two steps; other Ps agree/disagree correct answer. T writes solution on BB; praises. A mins Looking at denominators T: On the BB you can see some decimals converted into fractions, written in their simplest forms. What do you notice about the denominators of the simplest form fractions? What kind of numbers can or cannot be denominators of fractions written in their simplest forms? Why? Ps dictate, T writes on BB (Ps in Ex.Bs): = 0 = 00 = 0 = 0 = 0 0 = 00 = 0 8 = 0 Work remains on BB from homework and, and now Ps examine the denominators in the answers. T questions Ps and arrives at reasons why numbers such as sevenths and thirds cannot be denominators after simplification of fractions derived from converting decimals. Finally Ps give the pairs of multipliers that give, or 0 as a product.
A B UNIT Fractions and Lesson Plan T: So, can we write as a decimal? (Yes, we can convert it into tenths) T: How do we do that? ( 6 = = 06. ) T: And what about?

Never mind, we can use what we have learnt in this unit to check the answer. Volunteer P at BB: 68 = = 68. T: This method is much quicker. Which method will you choose to convert the next fraction? Ps: We'll divide. T: OK, it's up to you. P at OHP:. (a)... (b) 8 = (.6) T: Who'd like to show the other method? Ps:? T (encouraging): Can you get, or 0 by multiplying 8 by a whole number?

They all discuss what they have discovered about these fractions, that they have decimal forms, but without an end. Ps realise that, after some decimal places, the digits are repeated. When calculating, P must be encouraged to continue until the repetitions are obvious. Finally T tells Ps that they will deal with this problem later, and, until then, it will be enough to determine the first or nonzero digits after the decimal point, depending on the requirements of the task.

In today's society, most countries think in hundredths when speaking about changes. What other name do we give to these hundredths? Some Ps:. T: Yes, we call them percentages. The word comes from two Latin words, per meaning 'through' and centum meaning 'hundred'. What is the symbol we use for 'percent'? Volunteer P at BB: (%) T: Good.

For the first question, T suggests that Ps think carefully which method is the quicker and whether it helps to simplify the fraction. When P has given all the method () solutions, T calls another P to give solutions by method (), at BB. Agreement. Finally, after discussion T and Ps decide that as a general rule, the % of a quantity can be calculated by dividing the quantity by and then multiplying the quotient by x.
